RAYMOND HALL and KEITH R. KELSON In preparing maps showing the geographic distribution of North American mammals we have found in the literature conflicting statements and questionable identifications, which have led us to examine the specimens concerned with results as set forth below. Our studies have been aided by a contract (NR 161-791) between the Office of Naval Research, Department of the Navy, and the University of Kansas. Grateful acknowledgment is made to the persons in charge of the several collections of mammals consulted for permission to examine and study the specimens therein. ~Didelphis marsupialis californica~ Bennett From Cuernavaca, Morelos, Hooper (Jour. Mamm., 28:43, February 1, 1947) lists a specimen, as he says, on purely geographic grounds, as of the subspecies _Didelphis mesamericana tabascensis_. We have examined this specimen, an unsexed skull-only, which falls within the range of individual variation of _Didelphis marsupialis californica_ and refer the specimen to that subspecies. ~Didelphis marsupialis etensis~ J. A. Allen From El Muñeco, Costa Rica, Harris (Occas. Papers, Mus. Zool. Univ. Michigan, no. 476:7, October 8, 1943) lists as _Didelphis richmondi_ a specimen ([Male], No. 67550 U.M.). Our examination of the specimen shows it to be within the range of individual variation of populations that have been referred to _D. m. etensis_ from adjoining areas. We identify the specimen as _Didelphis marsupialis etensis_. ~Didelphis marsupialis tabascensis~ J. A. Allen From Minatitlán, Veracruz, J. A. Allen (Bull. Amer. Mus. Nat. Hist., 14:168, June 15) listed a specimen under the name _Didelphis marsupialis_ [in the trinomial sense] instead of under the name _Didelphis marsupialis tabascensis_, which would be expected, on geographic grounds, to apply. The specimen is No. 78123, U.S. Nat. Mus., Biol. Surv. Coll. Our examination of the specimen reveals that it is within the range of individual variation of _Didelphis marsupialis tabascensis_ and we identify the specimen as of that subspecies. From Yaruca, Honduras, Bangs (Bull. Mus. Comp. Zool., 39:157, July, 1903) doubtfully listed as _Didelphis yucatanensis_ a specimen, No. 10611, M.C.Z. Our examination of the specimen indicates that it is within the range of variation expectable in _Didelphis marsupialis tabascensis_, known from surrounding areas, and we identify the specimen as _Didelphis marsupialis tabascensis_. ~Didelphis marsupialis virginiana~ Kerr J. A. Allen (Bull. Amer. Mus. Nat. Hist., 14:166, May 28, 1901) and A. H. Howell (N. Amer. Fauna, 45:20, October 28, 1921) have identified four skulls from Sylacuga, Alabama, as _Didelphis virginiana pigra_. The two subspecies _virginiana_ and _pigra_ are not known to differ cranially. We have, however, examined the skulls which are Nos. 44057-44060 in the U.S. Nat. Mus., Biol. Surv. Coll. Because they are from a place north of other localities (Auburn and Greensboro, Alabama) from which the subspecies _virginiana_ has been recorded, and within the geographic range of _virginiana_, we identify the specimens as _Didelphis marsupialis virginiana_. Sycamore Creek (synonymous with Fort Worth), Texas, is a place from which J. A. Allen (_op. cit._:173) recorded a specimen as _Didelphis marsupialis texensis_. This specimen (No. 24359/31765 U. S. Nat. Mus., Biol. Surv. Coll.) is in the black color-phase. There are only a few white hairs on the hind feet, and the basal fourth of the tail is black. The black phase occurs all through the range of the species _D. marsupialis_ and our examination of the specimen reveals no characters by which it can be distinguished from _D. m. virginiana_ of the surrounding region and we accordingly identify the specimen as _Didelphis marsupialis virginiana_. ~Didelphis marsupialis pigra~ Bangs Davis (Jour. Mamm., 25:375, December 12, 1944) was one writer who presented evidence that _Didelphis virginiana_ (through its subspecies _virginiana_ or _pigra_ or both) was only subspecifically distinct from the species _Didelphis mesembrinus_ (= _D. marsupialis_) through the subspecies _texensis_. Davis, however, did not actually employ a name combination that would enforce his conclusion and he remarked that he had not seen specimens which showed actual intergradation in the color of the toes. As the remarks below will show, Davis (_loc. cit._) was correct in his supposition that J. A. Allen had seen such specimens. Deming Station, Matagordo, and Velasco, Texas, are three places from which J. A. Allen (Bull. Amer. Mus. Nat. Hist., 14:162, May 28, 1901) listed specimens as _Didelphis virginiana_. The specimens concerned are in the Biological Surveys Collection of the U.S. Nat. Museum and bear catalogue numbers as follows: Deming Station, 32430/44266, 32432/44268, 32433/44269; Matagordo, 32431/44267; Velasco, 32812/44833. In each specimen the tail is shorter than the head and body. The specimen from Velasco is semi-black, has the basal tenth of the tail black and there is no white on the ears or tail. The specimen from Matagordo is grayish, has the basal fifth of the tail black, ears black, the right hind foot black, but there is some white on the toes of the left hind foot and on each of the forefeet. Of the three specimens from Deming Station, all are in the gray color-phase. The first has the tail black only as far from the base as there is hair and there is considerable whitish on the hind toes. The second specimen has the basal fifth of the tail black and a slight amount of whitish on the hind toes. The third specimen has the basal third of the tail black and the toes are all black. In the sum total of their characters the specimens mentioned above are referable to _Didelphis marsupialis pigra_. These five specimens, and indeed the three from Deming Station alone, show intergradation in coloration of the feet between _Didelphis marsupialis texensis_ and _Didelphis virginiana pigra_. Probably there is three-way intergradation here at Deming Station in that _D. v. virginiana_ immediately to the north is involved. The specimens mentioned above, along with the information recorded by Davis (_loc. cit._) and other authors (for example, J. A. Allen, _loc. cit._, and Bull. Amer. Mus. Nat. Hist., 16:249-279, August 18, 1902), give basis for arranging the North American _Didelphis_ as follows: _Didelphis marsupialis virginiana_ Kerr. 1792. _Didelphis virginiana_ Kerr, Animal Kingdom, p. 193, type locality Virginia. _Didelphis marsupialis pigra_ Bangs. 1898. _Didelphis virginiana pigra_ Bangs, Proc.

In listing the subspecific names given immediately above we are aware of the possibility that a thorough study of the geographic variation in _Didelphis marsupialis_ may contract or expand the list of recognizable subspecies. We are aware also that Hershkovitz (Fieldiana: Zoology, 31 (No. 47):548, July 10, 1951) has arranged several of the subspecific names listed immediately above as synonyms of _Didelphis marsupialis californica_ Bennett. We have not employed his arrangement because he has not given proof that the currently recognized subspecies are indistinguishable. ~Caluromys derbianus canus~ (Matschie) Matschie (Sitzungsberichte der Gesellschaft Naturforschender Freunde zu Berlin, Jahrgang 1917, p. 284 (for April), September, 1917) applied the name _Micoureus canus_ to a specimen on which the locality was no more precise than Nicaragua. Comparison of Matschie's description with specimens in the United States National Museum (including the holotype of _Philander centralis_ Hollister and referred specimens of _Philander laniger pallidus_ Thomas) reveals that Matschie's specimen was intermediate in coloration between the other two kinds of woolly opossums named above and that there is nothing distinctive, in the specific sense, in the cranial measurements which Matschie published (_op. cit._). _M. canus_, therefore, may be merely an intergrade between the two previously named woolly opossums (_C. d. centralis_ and _C. d. pallidus_), an individual variant of a previously named kind, say, _C. d. pallidus_, or a valid subspecies. If it is a recognizable subspecies, it probably comes from somewhere in the eastern half of Nicaragua. As a means of handling the name, _Micoureus canus_ Matschie, we tentatively place it as a subspecies of the species _Caluromys derbianus_. The name may, therefore, stand as _Caluromys derbianus canus_ (Matschie), with type locality in Guatemala. ~Caluromys derbianus fervidus~ (Thomas) Elliott (Field Columb. Mus. Nat. Hist., Publ. No. 115, Zool. Ser., 8:5, 1907) lists as _Caluromys laniger pallidus_ a specimen from Honduras that was acquired for the Field Columbian Museum (= Chicago Natural History Museum) by purchase from Ward's Natural Science Establishment of Rochester, New York. On August 4, 1951, in the Chicago Natural History Museum, we found in the catalogue of the collection of Recent mammals an entry for a male _Caluromys_ bearing catalogue number 6 and listed as from "San Pedro Sula [Honduras]. From Wards. Mounted". In the collection of study specimens there is no specimen from Honduras that was purchased from Ward's, mounted or unmounted. In the sealed, glass-fronted, exhibit cases of mammals on display there is one, and only one, _Caluromys_. It is presumed to be specimen No. 6. This specimen is not _C. d. pallidus_ because it is too dark. It could be _Caluromys derbianus fervidus_ and we tentatively refer it to that subspecies. ~Caluromys derbianus pallidus~ (Thomas) From Puntarenas, Costa Rica, Harris (Occas. Papers Mus. Zool. Univ. Michigan, 476:7, October 8, 1943) listed as _Caluromys laniger centralis_ a female, skull and skin, No. 62702 in the Museum of Zoology of the University of Michigan. We have examined this specimen, the color of which is darker than in some other specimens of _C. d. pallidus_ but lighter than that of specimens of _C. d. centralis_ (for example, specimens from Turrialba, Costa Rica) and on basis of color we refer No. 62702 to _Caluromys derbianus pallidus_. ~Scalopus aquaticus aereus~ (Bangs) Bangs' (Proc. Biol. Soc. Washington, 10:138, December 28, 1896) name _S. a. aereus_ was based on a single specimen that shows more than an average amount of coppery color. Jackson (N. Amer. Fauna, 38:52, September 30, 1915) and subsequent authors accord full specific rank to the specimen under the name _Scalopus aereus_. Blair (Amer. Midland Nat., 22:98, July, 1939) recorded, from the type locality of _Scalopus aereus_, normally colored individuals of _Scalopus aquaticus pulcher_ Jackson. Previously, Scheffer (Kansas State Agric. College, Exp. Bull., 168:4, August 1, 1910) reported that in his examination of 100 individuals of _Scalops_ [= _Scalopus_] _aquaticus_ from Manhattan, Kansas, there were two individuals "that were suffused all over with rich golden brown." Because our examination of the type specimen of _Scalops texanus aereus_ Bangs reveals no features additional to coppery color that differentiate _aereus_ from other individuals of _Scalopus aquaticus pulcher_ Jackson (Proc. Biol. Soc. Washington, 27:19, February 2, 1914) we conclude that Jackson's name and Bangs' name (_Scalops texanus aereus_) apply to the same subspecies. Bangs' name has priority and the correct name, therefore, for the populations of moles that in recent years have been designated as _Scalopus aereus_ Bangs and _Scalopus aquaticus pulcher_ Jackson will be _Scalopus aquaticus aereus_ (Bangs). This name combination was previously used by Miller (U.S. Nat. Mus. Bull., 79:8, December 31, 1912). ~Scalopus aquaticus australis~ (Chapman) Quay (Jour. Mamm., 30:66, February 14, 1949) recorded _Scalopus aquaticus_ from Springhill Plantation, 10 miles south-southwest of Thomasville, Georgia. He stated that the specimens were intermediate between the subspecies _S. a. australis_ and _S. a. howelli_, but did not refer the specimens to either subspecies. The locality whence the material was obtained is approximately half way between the geographic ranges, as previously known, of _S. a. australis_ and _S. a. howelli_ (see Jackson, N. Amer. Fauna, 38, September 30, 1915). The specimens recorded by Quay probably are two females in the Cleveland Museum of Natural History bearing Catalogue Nos. 18136 and 18262 and labeled as from Springhill Plantation, Thomas County, Georgia. We have examined these specimens and find that they resemble _S. a. howelli_ in narrowness across the upper tooth-rows, but that they resemble _S. a. australis_ in length of tail (22, 24), in shortness of maxillary tooth-row (9.5, 9.5), and in convex dorsal outline of the skull. Accordingly, we refer the specimens to _Scalopus aquaticus australis_. ~Sorex cinereus cinereus~ Kerr In his revision of the American long-tailed shrews, Jackson (N. Amer. Fauna, 51, vi + 238, 13 pls., 24 figs., July 24, 1928) referred specimens of _Sorex cinereus_ from Tyonek, Cook Inlet, Alaska, to the subspecies _S. c. cinereus_ (_op. cit._: 46) and one specimen from Chester Creek, Anchorage, Alaska, to the subspecies _S. c. hollisteri_ (_op. cit._: 56). Thus, the geographic ranges of the two subspecies would seem to overlap around the northern shores of Cook Inlet. In an attempt to resolve this seemingly anomalous distribution, we have examined pertinent materials in the Biological Surveys Collection, U.S. National Museum. We agree with Jackson (_op. cit._) that the series of specimens from Tyonek is readily referable to _S. c. cinereus_. To our eye, however, the specimen, No. 232691, from Anchorage is referable to _Sorex cinereus cinereus_, rather than to _S. c. hollisteri_. The reference is made on the basis of the darker color, especially of the underparts. In this specimen, other characters that distinguish the two mentioned subspecies are not apparent, probably because it is relatively young; the teeth show only slight wear. ~Sorex trowbridgii humboldtensis~ Jackson In his account of the long-tailed shrews, Jackson (N. Amer. Fauna, 51:98, July 24, 1928) listed under specimens examined of _Sorex trowbridgii montereyensis_ four specimens from 7 mi. N Hardy, Mendocino Co., California. Under his account of the subspecies _S. t. humboldtensis_, however, he (_op. cit._:97) mentions that specimens (seemingly the same four) from 7 mi. N Hardy "have shorter tails than typical representatives of _humboldtensis_, but in color and cranial characters they are similar to this [_humboltensis_] subspecies." We conclude, therefore, that the specimens mentioned were inadvertently listed as _S. t. montereyensis_ and are _Sorex trowbridgii humboldtensis_. This conclusion is supported by the fact that the locality concerned, 7 mi. N Hardy, is within the geographic range assigned to _S. t. humboldtensis_ by Jackson (_op. cit._:97); his southern records of occurrence of _S. t. humboldtensis_ are Sherwood and Mendocino, both in Mendocino County, California. Our conclusion is further supported by Grinnell's (Univ. California Publ. Zool., 40(2):80, September 26, 1933) statement of the range of _S. t. montereyensis_ as "from southern Mendocino County south...." ~Blarina brevicauda churchi~ Bole and Moulthrop Kellogg (Proc. U.S. Nat. Mus., 86:253, February 14, 1939) tentatively referred specimens of the short-tailed shrew from the mountainous parts of eastern Tennessee to the subspecies _Blarina brevicauda talpoides_, with the remark that they were unlike specimens of that subspecies obtained in eastern and southern West Virginia. Subsequently, Bole and Moulthrop (Sci. Publ. Cleveland Mus. Nat. Hist., 5:109, September 11, 1942) named the subspecies _Blarina brevicauda churchi_ with type locality at Roan Mountain, North Carolina. We have examined the specimens in the U.S. National Museum recorded by Kellogg (_loc. cit._) from the following localities: Shady Valley, 2900 ft. (Catalogue No. 267182); Holston Mtn., 4 mi. NE Shady Valley, 3800 ft. (Nos. 267176-267178, 267180, and 267181); Holston Mtn., 3 mi. NE Shady Valley, 3000 ft. (No. 267179); Roan Mtn., (Nos. 267469-267475); Mt. Guyot, 6300 ft. (No. 267183); 4-1/2 mi. SE Cosby, 3300 and 3400 ft. (Nos. 267184 and 267185); and Snake Den Mtn., 3800 ft. (No. 267186). Among named kinds of _Blarina brevicauda_, we find these specimens to resemble most closely _Blarina brevicauda churchi_ and so refer them. They are readily distinguishable from specimens of _B. b. kirtlandi_, that occurs farther north in the same mountain range, by larger size and longer tail. Incidentally, in the specimens that we have examined, we do not find that _B. b. churchi_ is darker colored than other subspecies of _Blarina brevicauda_; _B. b. churchi_, to us, is indistinguishable in color from _B. b. kirtlandi_. Bole and Moulthrop (_op. cit._) thought that _B. b. churchi_ was notably darker than other subspecies from adjoining areas. ~Blarina brevicauda carolinensis~ (Bachman) Blair (Amer. Midland Nat., 22(1):99, July, 1939) referred specimens of the short-tailed shrew from the Arbuckle Mountain area of Oklahoma to _Blarina brevicauda hulophaga_ and specimens from Mohawk Park, Tulsa County, Oklahoma, to _B. b. carolinensis_. Later Bole and Moulthrop (Sci. Publs. Cleveland Mus. Nat. Hist., 5:108, September 11, 1942) saw two of the specimens from Mohawk Park and assigned them to _B. b. hulophaga_. According to the most recent published account, therefore, _B. b. hulophaga_ would seem to have a peculiarly discontinuous geographic range. We have examined the material seen by Blair and by Bole and Moulthrop (Nos. 75946, 75947, 75643, Mus. Zool. Univ. Michigan) in an attempt to form our own judgment as to their subspecific identity. The teeth of No. 75946 are well worn, whereas the teeth of the other two are scarcely worn. We are unable to distinguish No. 75946 from topotypes of _B. b. carolinensis_ by size, color, or cranial features. The two younger specimens are smaller and paler, but do not agree with the description of _B. b. hulophaga_. The nearly-complete narrow, white girdle of No. 75947 is clearly an individual variation. We assign the animals to _Blarina brevicauda carolinensis_ (Bachman) as did Blair (_loc. cit._). ~Blarina brevicauda minima~ Lowery Bailey (N. Amer. Fauna, 25:207, October 24, 1905) identified as _Blarina brevicauda carolinensis_ one specimen from Joaquin and two specimens from Big Thicket, 8 mi. NE Sour Lake, both localities in eastern Texas. Strecker and Williams (Jour. Mamm., 10:259, August 10, 1929) later recorded the specimens again under the same name. The subsequent naming of _B. b. plumbea_ from Aransas National Wildlife Refuge, Aransas County, Texas (Davis, Jour. Mamm., 22(3):317, August 14, 1941) and _B. b. minima_ from Louisiana (Lowery, Occas. Papers Mus. Zool., Louisiana St. Univ., 13:218, November 22, 1943) leaves the identity of the specimens from eastern Texas in doubt. We have examined the following specimens in the Biological Surveys Collection, U.S. National Museum: No. 117372, from Joaquin; No. 136407, from 7 mi. NE Sour Lake; and No. 136788, from 8 mi. NE Sour Lake. We judge these to be the specimens referred to by Bailey (_loc. cit._). We find that they are indistinguishable from specimens of _Blarina brevicauda minima_ and they seem to differ from _B. b. plumbea_ in being chestnut rather than plumbeous in color and in lacking the highly-arched posterior border of the palate. They are easily distinguished from _B. b. carolinensis_ by their chestnut, rather than slaty-black, color and small size. They are distinguishable from _B. b. hulophaga_, to which they might conceivably be referred on geographic grounds, by their color and small size. We refer them to _Blarina brevicauda minima_ Lowery. ~Spilogale angustifrons angustifrons~ A. H. Howell In his "Revision of the skunks of the genus Spilogale" (N. Amer. Fauna, 26, November 24, 1906) A. H. Howell identified certain specimens in the United States National Museum as follows: _Spilogale leucoparia_, [Male] sad. 55585 from Tulancingo, Hidalgo (_op. cit._:21). _Spilogale gracilis_, [Male] sad. 88154 from San Sebastian in Jalisco, [Male] ad. 79017 from Lagos in Jalisco, [Male] ad. 47177 from Pátzcuaro in Michoacán (_op. cit._:23). _Spilogale ambigua_, [Male] ad. 35667/20437 from Barranca Ibarra in Jalisco, [Male] yg. 120101 from Ocotlán in Jalisco (_op. cit._:25). Hall and Villa (Univ. Kansas Publ., Mus. Nat. Hist, 1:448, December 27, 1949) inferred that No. 47177 from Pátzcuaro was instead referable to _Spilogale angustifrons angustifrons_. Our examination of No. 47177 and of each of the other specimens mentioned by catalogue number immediately above leads us to conclude that they all are of one species, and that, among named kinds of _Spilogale_, they should be referred to the subspecies _Spilogale angustifrons angustifrons_ Howell. Our examination of all of the specimens that Howell (_op. cit_.) identified as _Spilogale [angustifrons] angustifrons_ reveals that none of the specimens from the type locality had attained full adult stature; the holotype is a subadult and the other specimens from the type locality are even younger. The small size of these specimens from the type locality seems to have misled Howell into thinking that they were taxonomically distinct from the larger specimens--those from Jalisco, Michoacán and Hidalgo--that he identified as other kinds. ~Spilogale gracilis gracilis~ Merriam In the genus _Spilogale_ four specific names, concerning the status of which we have been uncertain, are listed below in the order of their appearance in the literature. 1890. _Spilogale gracilis_ Merriam, N. Amer. Fauna, 3:83, September 11, type from bottom of canyon, Grand Canyon, Arizona. 1890. _Spilogale leucoparia_ Merriam, N. Amer. Fauna, 4:11, October 8, type from Mason, Mason County, Texas. 1891. _Spilogale phenax arizonae_ Mearns, Bull. Amer. Mus. Nat. Hist., 3:256, June 5, type from near Fort Verde, Yavapai County, Arizona. 1897. _Spilogale ambigua_ Mearns, Preliminary diagnoses of new mammals ... from the Mexican boundary line, p. 3, January 12 [reprinted in Proc. U.S. Nat. Mus., 20:460, December 24, 1897], type from summit of Eagle Cliff Mtn., 2 mi. S of Monument No. 5 of Emory's Survey which, according to Miller (U.S. Nat. Mus. Bull., 128:134, April 29, 1924), is "Eagle Mountain, Chihuahua, Mexico, about four miles south of Dona Ana County, New Mexico." In 1906 (N. Amer. Fauna, 26:1-55, 10 pls., November 24) A. H. Howell's "Revision of the skunks of the genus Spilogale" was published and the four names listed above were retained by him as applying to four species (not subspecies). His map (_op. cit._, pl. 1) showing the geographic distribution of the four kinds looks reasonable enough at first inspection and does not indicate any overlapping of the geographic ranges of the species in question, but if a map be made by plotting the localities of occurrence recorded by Howell (_op. cit._), for specimens examined by him, a notably different geographic distribution is shown. For one thing the geographic ranges of _gracilis_, _leucoparia_, _arizonae_ and _ambigua_ coincide over a considerable part of Arizona. Also, specimens collected in recent years from Arizona and adjoining areas do not readily fit into the "species" recognized by Howell; some specimens are structurally intermediate between two or more of these species and other specimens combine the diagnostic characters ascribed to two or more of the alleged species. For these and other reasons a re-appraisal of the application of the names mentioned above long has been indicated. Before re-appraising the names it is pertinent to recall that Howell's paper in 1906 on _Spilogale_ was only the second revisionary paper that he prepared. It was prepared by a man who at that time lacked much taxonomic experience, and who held to a morphotype concept. Howell worked under the guidance, in the literal sense, of Dr. C. Hart Merriam. The concept of species and subspecies held by Merriam fortunately was recorded by him (Jour. Mamm., 1:6-9, November 28, 1919). Merriam's reliance on degree of difference and his disregard of intergradation were naturally (and necessarily, we think, in Howell's work in 1906) adopted by Howell. For example, of six specimens from Point Reyes in west-central California, a place less than ten miles from the type locality of _Spilogale phenax phenax_, Howell (_op. cit._:33) assigned one specimen to the subspecies _Spilogale phenax latifrons_! _S. p. latifrons_ occurs in Oregon and in northern California--no nearer than 200 miles to Point Reyes. Howell's assignment of this specimen to _S. p. latifrons_ was not a _lapsus_, as persons with the modern (geographic) concept of a subspecies would be likely to suppose. Howell's assignment of the one specimen to _S. p. latifrons_ and the other five specimens to _S. p. phenax_ was intentional, as he told one of us (Hall). He explained that he relied upon the morphological characters of the individual animal instead of upon the morphological characters of a population of animals. To him, therefore, there was nothing inconsistent in his procedure in 1906. Also, variation that was the result of difference in age and variation that was the result of individual deviation were not understood, or at least not taken into account, by Howell in 1906, nor by Merriam in 1890. For example, Merriam selected the most extensively white specimen available to him for the holotype of _Spilogale leucoparia_. He, and Howell in 1906, used the extensiveness of the white areas of that particular specimen (see fig. 3, pl. 2, N. Amer. Fauna, 26, 1906) as a character diagnostic of the "species" _S. leucoparia_ although each of the authors had available two other specimens of _S. leucoparia_ from the type locality, and all of the other referred specimens in the United States National Museum, that were less extensively white than the holotype. The _individual specimen_ was the primary basis for the species or subspecies and one selected specimen alone often was used in making comparisons between a given named kind and some other species or subspecies. Also, be it remembered, degree of difference, and not presence or absence of intergradation, was the basis on which subspecific _versus_ specific rank was accorded to a named kind of animal. Howell wrote on the labels of some specimens of _Spilogale_ "not typical" when the individuals differed from the type specimen in features that owe their existence to individual variation, and he wrote the same words on the labels of other specimens that had not yet developed mastoidal crests because the animals were not yet adult. Anyone who examines the specimens that Howell used will do well to bear in mind the circumstances noted above concerning Howell's paper of 1906; otherwise the reasons for Howell's identifications of certain specimens can not be understood. We have examined and compared the holotypes, and other specimens used by Howell. While doing so we have borne in mind the degree of individual variation well shown by each of several series of specimens (for example, that in six adult males, from the Animas Mountains of New Mexico, recorded by V. Bailey, N. Amer. Fauna, 53:339, 1932) and age variation (for example, that shown in specimens of _S. interrupta_ from Douglas County, Kansas). The degree of each of these kinds of variation, although considerable, is not extraordinary. That is to say, the variations are of approximately the same degree as we previously have ascertained to exist in _Mephitis mephitis_ and in _Mustela frenata_, two species that are in the same family, Mustelidae, as _Spilogale_. As a result of our comparisons, we conclude, first that the four names mentioned at the beginning of this account all pertain to one species, and second that the three names _S. gracilis_, _S. p. arizonae_ and _S. ambigua_, and probably also _S. leucoparia_, were based on individual variations in one subspecies. _S. gracilis_ has priority and will apply; the other names are properly to be arranged as synonyms of it, as follows: 1890. _Spilogale gracilis_ Merriam, N. Amer. Fauna, 3:83, September 11. 1890. _Spilogale leucoparia_ Merriam, N. Amer. Fauna, 4:11, October 8. 1891. _Spilogale phenax arizonae_ Mearns, Bull. Amer. Mus. Nat. Hist., 3:256, June 5. 1897. _Spilogale ambigua_ Mearns, Preliminary diagnoses of new mammals ... from the Mexican boundary line, p. 3, January 12. Some information in support of the above arrangement, along with some other observations on _Spilogale_, are as follows: The type specimen of _Spilogale gracilis_ bears on the original skin-label in the handwriting of Vernon Bailey, the collector, the statement that the tail was imperfect. The recorded measurements of 400 for total length and 142 for length of tail, therefore, are presumed to be subject to correction. This presumption and the further circumstance that other specimens from Arizona and New Mexico are as large as specimens of comparable age and sex that we have examined from Nevada and Utah of _Spilogale gracilis saxatilis_ Merriam, indicate that _S. g. saxatilis_ differs less from the allegedly smaller _S. g. gracilis_ than was previously thought. Nevertheless, from north to south (for example, from northern Nevada to southern Arizona) there is an increase in extent of white areas at the expense of black areas of the pelage. As a result, the lateralmost white stripe in _S. g. saxatilis_ averages narrower (and often is wanting) than in _S. g. gracilis_. The absence, or narrowness, of the lateralmost white stripe seems to be the principal basis for recognizing _S. g. saxatilis_, just as the tendency to narrow rostrum in Coloradan specimens seems to be the principal basis for recognizing _Spilogale gracilis tenuis_ A. H. Howell. Both _S. g. saxatilis_ and _S. g. tenuis_ are "poorly" differentiated from _S. g. gracilis_ and from each other. The holotype of _Spilogale ambigua_ Mearns is slightly smaller than other adult males of comparable age, and the braincase, relative to its width, is slightly deeper than in the average adult male. These variations, nevertheless, are within the range of individual variation, as also are those characterizing the holotype of _Spilogale phenax arizonae_ Mearns. The latter specimen is an adult male, with much inflated mastoidal bullae, nearly straight dorsal profile on the skull, relatively shallow braincase, and only slightly worn teeth. The holotype of _Spilogale leucoparia_ Merriam, as pointed out above, is an extreme example of the extensiveness of the white areas of the pelage at the expense of the black areas. This feature occurs more often in the southwestern desert areas of the United States than it does farther north. In addition to the extensiveness of the white markings, the other two characters allegedly distinctive of _S. leucoparia_ are broad and much flattened braincase and great degree of inflation of the mastoidal bullae. Although these three mentioned features do distinguish _S. leucoparia_ from _S. indianola_ to the eastward, they seem not to set _S. leucoparia_ apart from _S. gracilis_ to the westward. For example, in Arizona some specimens are extensively white and some others have the braincase flattened and the mastoidal bullae much inflated. V. Bailey (N. Amer. Fauna, 53:339, 1932) refers to a specimen ([Male], No. 147252 USBS) from the head of the Rio Mimbres in New Mexico in which, as our comparisons show, the inflation of the mastoidal bullae exceeds that of any Texan specimen of _S. leucoparia_, the holotype included. Also, at the type locality of _S. leucoparia_, subadult male No. 188467 USNM and adult male No. 188468 USNM are narrower across the mastoidal region than is the holotype. In summary and review, specimens from the eastern part of the range heretofore ascribed to _S. leucoparia_ nearly all have much inflated mastoidal bullae whereas less than half of the specimens of _Spilogale_ from western New Mexico and Arizona have these bullae as greatly inflated; but, in No. 147252 from the head of the Rio Mimbres of New Mexico the inflation of the bullae is more extreme than in any specimen that we know of that has been referred to _S. leucoparia_. If intergradation occurs between _Spilogale gracilis gracilis_ and _Spilogale indianola_ and between one or both of these kinds on the one hand and _Spilogale interrupta_ on the other hand, central Texas would be a logical place to collect intergrades. We suppose that such intergradation will be found to occur and that eventually _Spilogale putorius_ will be the specific name to apply to all of the Recent subspecies of spotted skunks. Until proof of such intergradation is forthcoming we employ current nomenclature. ~Spilogale gracilis microdon~ A. H. Howell A. H. Howell (N. Amer. Fauna, 26:31, November 24, 1906) listed as _Spilogale arizonae martirensis_ one specimen ([Female] sad.-yg., 145886 USBS) from Comondú, which is the type locality of _S. microdon_. Our examination of [Female] No. 145886 convinces us that it is referable to _S. microdon_. Examination of the materials used by Howell (_op. cit._) reveals that there is an increase in size of animal and its skull from within the geographic range of _S. g. martirensis_ southward to Cape St. Lucas which is the type locality of _S. lucasana_. Specimens of _S. microdon_, which so far has been recorded only from Comondú, the type locality, are, as would be expected, intermediate in size between _S. g. martirensis_ and _S. lucasana_. The differential characters of these three named kinds of _Spilogale_ are principally those of size, and we can see no characters judged to be of more than subspecific worth. Consequently the named kinds should stand as: _Spilogale gracilis martirensis_ Elliott; _Spilogale gracilis microdon_ A. H. Howell; _Spilogale gracilis lucasana_ Merriam. ~Spilogale gracilis microrhina~ Hall When Hall (Jour. Mamm., 7:53, February 15, 1926) named as new _Spilogale phenax microrhina_, he did not mention specimens previously recorded by A. H. Howell (N. Amer. Fauna, 26:32, November 24, 1906) as _Spilogale phenax_ from San Bernardino Peak (57026 USBS), La Puerta (99580 USBS), Dulzura (55848, 56173, 56873, 33693/45728, 36291/48656 and 36292/48657) in southern California. On geographic grounds these specimens would be expected to be _S. g. microrhina_ although geographically slightly outside the area that could be delimited by Hall's (_op. cit._) marginal record-stations of occurrence. Our examination of the pertinent specimens reveals that they are _Spilogale gracilis microrhina_. The localities from which the specimens came are, respectively, the northeasternmost, easternmost and southernmost occurrences so far listed for the subspecies. ~Conepatus mesoleucus mearnsi~ Merriam Examination of the holotypes of _Conepatus filipensis_ Merriam, _Conepatus pediculus_ Merriam, _Conepatus sonoriensis_ Merriam, and _Conepatus mesoleucus mearnsi_ Merriam, and other specimens of the two kinds last named, convinces us that all are the same species and that the names should stand as follows: _Conepatus mesoleucus filipensis_ Merriam (type locality, Cerro San Felipe, Oaxaca); _Conepatus mesoleucus pediculus_ Merriam (Sierra Guadalupe, Coahuila); and _Conepatus mesoleucus sonoriensis_ Merriam (Camoa, Río Mayo, Sonora). One method of designating the ages of individuals in _Conepatus_ is to recognize four categories from younger to older, as follows: 1) juvenile--retaining one or more deciduous teeth; 2) young--sutures open and clearly to be seen between bones of the facial part of the skull; 3) subadult--skull of adult form, but lacking sagittal and lambdoidal crests and retaining faint traces of sutures between facial bones; and 4) adult--sutures obliterated, lambdoidal ridge high and temporal ridges (of females) or sagittal crest (of males) prominent. On this basis of designating age, the holotype of _C. pediculus_ is young and nearer the juvenal than the subadult stage. Its small size is partly the result of its youth. Other than its small size we find no characters to distinguish it from _C. m. mearnsi_. Unfortunately no young male of _C. m. mearnsi_ of the same age as the holotype of _C. pediculus_ is available. Also, from the general area of the Sierra Guadalupe, Coahuila, only the one specimen of _Conepatus mesoleucus_ (the holotype of _C. m. pediculus_) is known. Consequently, we can not yet prove that some young males of _C. m. mearnsi_ are as small as the holotype of _C. pediculus_. Because of this lack of proof we tentatively recognize the subspecies _Conepatus mesoleucus pediculus_ instead of placing the name _Conepatus pediculus_ in the synonomy of _Conepatus mesoleucus mearnsi_. The holotype of _C. sonoriensis_ is a young female, older than the holotype of _C. pediculus_, and approximately midway between the juvenal and subadult stages. The holotype of _C. filipensis_ is an adult male. We suppose that _C. mesoleucus mesoleucus_ Lichtenstein and _C. mesoleucus mearnsi_ Merriam on the one hand, and _Conepatus leuconotus leuconotus_ Lichtenstein and _C. l. texensis_ Merriam on the other hand will be found to intergrade, in which event the name _Conepatus leuconotus_, having page priority over _Conepatus mesoleucus_, will apply to the species. Proof of complete intergradation is not yet available. The one difference between the two that prevents our uniting them as subspecies of one species is the larger size of _C. l. leuconotus_ and _C. l. texensis_. Measurements of the smallest adult male and female available to us of _C. l. texensis_ and of the largest adult male and female of _C. m. mearnsi_ are given below. Where the geographic ranges of the two species approach one another the only taxonomically significant difference detected by us is in size, _C. leuconotus_ being larger than _C. mesoleucus_. Other characters that are useful in separating the two alleged species now are known to vary geographically in a fashion that indicates only subspecific status for the two kinds. For example, three specimens from Laredo, Texas (previously recorded by V. Bailey, N. Amer. Fauna, 25:205, October 24, 1905--Nos. 24839/32237, 24840/32238 and 24842/32245 USBS), bridge the gap in color pattern between _C. l. texensis_ to the east and _C. m. mearnsi_ to the west. _C. l. texensis_ characteristically has the white stripe terminating anteriorly in an obtuse angle, and on the hinder back the area of white is restricted to a narrow line or is wanting. _C. m. mearnsi_ characteristically has the white stripe truncate anteriorly and approximately as broad on the hinder back as on the shoulders. In the specimens from Laredo, the young female, No. 24842, has the white nearly truncate anteriorly (pointed in the other two specimens, adult females). In No. 24839 the area of white on the hinder back is only slightly restricted in width (noticeably restricted but present in the other two specimens). The proof of intergradation, or the lack of it, between the two alleged species, _Conepatus mearnsi_ and _Conepatus leuconotus_, would seem to be profitably sought by obtaining specimens along the Rio Grande in Texas between the Blocker Ranch ("50 miles southeast of Eagle Pass") and Laredo. Measurements illustrating the size difference between the two alleged species are as follows: TABLE 1. Measurements of _Conepatus_ from Texas Column Heading Legend: Col.

Mamm., 3:40, February 10, 1921) named _C. m. venaticus_ from Arizona he did not mention material which Merriam (Proc. Biol. Soc. Washington, 15:163, August 6, 1902) had recorded from Ft. Verde, Arizona, under the name _Conepatus mesoleucus mearnsi_. This material seems to be specimens in the American Museum of Natural History of which the two oldest specimens are as follows: No. 2486/1921, male, adult, from Box Cañon, 20 mi. S Ft. Verde; No. 2487/1922, female, subadult, from Verde River, Arizona. Pertinent measurements of these specimens are, respectively, as follows: condylobasal length, 72.4, 68.8; zygomatic breadth, 50.0, 44.2; width of braincase at constriction behind zygomata, 36.4, 33.8; mastoidal breadth, 44.3, 38.4. Comparison of these measurements with those given for _C. m. venaticus_ (Goldman, _loc. cit._) reveals that the specimens concerned agree in narrowness of skull with _C. m. venaticus_ (_C. m. mearnsi_ is relatively wider) and it is on this basis that we refer the specimens to _Conepatus mesoleucus venaticus_. ~Urocyon cinereoargenteus costaricensis~ Goodwin J. A. Allen (Bull. Amer. Mus. Nat. Hist., 20:48, February 29, 1904) listed two specimens of gray fox from Pozo Azul, Costa Rica, as _Urocyon guatemalae_. Goodwin, in his "Mammals of Costa Rica" (Bull. Amer. Mus. Nat. Hist., 87(5):271-474, December 31, 1946) did not mention any material from Pozo Azul. We have examined the skull of the adult female (No. 19208 AMNH) taken on July 17, 1902, at Pozo Zul [sic], by M. A. Carriker and find it to be indistinguishable from other specimens of _Urocyon cinereoargenteus costaricensis_ to which subspecies we therefore refer the specimen. ~Canis lupus griseoalbus~ Baird In 1823 Sabine (No. V, Zoological Appendix, p. 654, _In_ Narrative of a journey to the shores of the Polar Sea ... xvi + 768, 30 pls., 4 maps, 1823, London, by John Franklin) applied the name _Canis Lupus-Griseus_ to the gray wolf in the vicinity of Cumberland House, Saskatchewan. On the following page (p. 655) he employed the name _Canis Lupus-Albus_ for a white wolf obtained at Fort Enterprise, Northwest Territories. In 1937 Goldman (Jour. Mamm., 18(1):45, February 14) did not consider the wolves of the Cumberland House region to be sufficiently different from animals from surrounding areas to warrant nominal separation for them and he placed the name _Canis lupus griseus_ Sabine as a synonym of _Canis lupus occidentalis_ Simpson. Anderson (Jour. Mamm., 24(3):386, August 17, 1943) revived Sabine's name _griseus_ and assigned to _Canis lupus griseus_ an extensive geographic range in central Canada. Later, Goldman (Part II, Classification of wolves, p. 395 and 424, _In_ The Wolves of North America, American Wildlife Institute, May 29, 1944) by implication, again arranged _griseus_ of Sabine as a synonym of _Canis lupus occidentalis_ and pointed out (_op. cit._:395) that, in any event, the name _griseus_ is preoccupied by _[Canis] Griseus_ Boddaert, 1784 [= _Urocyon cinereoargenteus_ (Schreber), 1775]. Still later, Anderson (Bull. 102, Nat. Mus. Canada, p. 54, January 27, 1947) again recognized the subspecies formerly known as _Canis lupus griseus_ Sabine, and, because of Boddaert's prior usage of _[Canis] griseus_, renamed the subspecies _Canis lupus knightii_. It appears, however, that there is an earlier name available for this subspecies. Goldman (_op. cit._, 1943:395) points out that "apparently combining the names _Canis (Lupus) griseus_ and _Canis (Lupus) albus_ of Sabine ... as _Canis occidentalis_ var. _griseo-albus_, Baird [Mammals, Repts. Explor. and Surv. for R. R. to Pacific Ocean, Washington, p. 104, vol. 8, (1857) July 14, 1858] seems to have entertained a somewhat composite concept of a widely ranging race varying in color from 'pure white to grizzled gray.' No type was mentioned and the name does not appear to be valid or clearly assignable to the synonomy of any particular race." We agree with Goldman that Baird's concept was a composite one, but Baird's name, _Canis occidentalis_ var. _griseo-albus_, was clearly based on the primary names of Sabine (_griseus_ and _albus_), of De Kay (_occidentalis_), of Maxmillian (_variabilis_, a synonym of _Canis lupus nubilis_) and of Townsend (_gigas_, a synonym of _Canis lupus fuscus_). Nevertheless, the name _griseo-albus_ was applied to, among others, the subspecies of wolf the type locality of which is at Cumberland House, Saskatchewan, and, by restriction, the name _Canis lupus griseoalbus_ Baird is available for the subspecies and, of course, antedates _Canis lupus knightii_ of Anderson (_op. cit._, 1947:54). It might be argued that Baird did not intend to propose a new name, but that he did so is a _fait accompli_. _Canis lupus albus_ Sabine, 1823, is not available since it is preoccupied by _C[anis]. Lupus albus_ Kerr (Animal Kingdom, Class I, Mammalia, p. 137, 1792), a name applied to the wolf of the Yenisei region of Siberia. The name and synonomy of the wolf of central Canada should stand as follows: ~Canis lupus griseoalbus~ Baird 1858. _Canis occidentalis_, var. _griseo-albus_ Baird, Mammals, Repts. Explor. and Surv. for R. R. to Pacific Ocean, Washington, vol. 8, p. 104 (1857), July 14, 1858, based on _Canis Lupus-Griseus_ Sabine 1823 from the vicinity of Cumberland House, Saskatchewan. 1823. _Canis Lupus-Griseus_ Sabine, No. V, Zool. App. p. 654, _In_ Narrative of a journey to the shores of the Polar Sea ... by John Franklin (_nec [Canis] Griseus_ Boddaert, Elench. Anim. p. 97, 1794, a synonym of _Urocyon cinereaorgenteus_ (Schreber), Säugethiere, p. 92, 1775). 1943. _Canis lupus griseus_, Anderson, Jour. Mamm., 24(3):386, August 17. 1947. _Canis lupus knightii_ Anderson, Bull. 102, Nat. Mus. Canada, p. 54, January 24. (A renaming of _Canis Lupus-Griseus_ Sabine, 1823.) The name _Canis Lupus-Albus_ Sabine, 1823 (_nec C[anis]. Lupus albus_ Kerr, Animal Kingdom, p. 137, 1792) should, of course, be retained as a synonym of _Canis lupus mackenzii_ Anderson as arranged by Anderson (Bull. 102, Nat. Mus. Canada, p. 55, January 24, 1947). When Anderson (_op. cit._:54) recognized the subspecies _Canis lupus knightii_ [= _C. l. griseoalbus_] he made no mention of a specimen of wolf from Norway House, Manitoba, which Goldman (_op. cit._, 1944:427) had referred to _C. l. occidentalis_, but the subspecific identity of which was placed in doubt by Anderson's action. We have examined the specimen, No. 115995, in the Biological Surveys Collection, U.S. National Museum, and have compared it with specimens, including topotypes, of _C. l. occidentalis_ and _C. l. hudsonicus_. The specimen fits the description of _C. l. griseoalbus_ and differs from _C. l. occidentalis_ in its long and narrow incisive foramina, larger skull, more nearly straight frontal profile (not markedly concave), and slightly higher coronoid processes. Other differences alleged to obtain between these two subspecies offer no assistance in the present case. The specimen from Norway House differs from _C. l. hudsonicus_ in larger size of skull and stouter, blunter, postorbital processes, the posterior borders of which turn less abruptly inward. In brief, among currently recognized subspecies, the specimen from Norway House seems best referred to _Canis lupus griseoalbus_ Baird. ~Canis niger rufus~ Audubon and Bachman Goldman (Part II, Classification of wolves, p. 486, _In_ The wolves of North America, American Wildlife Institute, May 29, 1944) referred two specimens of the red wolf from Reeds Spring, Missouri, to the subspecies _C. n. gregoryi_. Leopold and Hall (Jour. Mamm., 26(2):143, July 19, 1945) referred wolves from 5 mi. N Gainesville and from 3 mi. N Thomasville, both localities in Missouri, to _C. n. rufus_. The identification of Leopold and Hall was made on the basis of the small size of their specimens and they did not have the advantage of comparative material. The locations of these and other records of occurrence in Missouri and Arkansas suggest that the specimens from Reeds Spring might be better referred to _C. n. rufus_, the more western subspecies. An examination and comparison of the two specimens from Reeds Spring, Nos. 244127 and 244527, Biological Surveys Collection, discloses that they are intergrades between _C. n. rufus_ and _C. n. gregoryi_. They resemble _C. n. rufus_ in small size and cranial characters, but are more nearly _C. n. gregoryi_ in the darker, less brightly rufescent color of the pelage. Being, in this case, more strongly influenced by the size and cranial features than by the color, we consider the animals from Reeds Spring best referred to _Canis niger rufus_. _Transmitted July 15, 1952._
