Tlie.se fossil remains iiuve received considerable attention on the part of the members of the (feoiogical Survey of Canada since early in the fifties, and numerous reports and ])ai)ers have appeared from lime to time both in the '■ Jteports of Progress'' publisluMJ by 'Jie Geological Survey of Canada and in the •Caiiitdiau Naturalist and (ii'ologisl."

Jones and others besides the present writer, hav« con- tributed .several reports and articles bearing upon the stratigraphy and paheontology of the district under consideration. it was the purpose of the ])resent writer to prepare for the Trans- actions of the lioyal Sociely an extensive .serie.s of classified lists of the fo.ssil organic remains ol)tained from all the localities examined within the (Ottawa Paheozoic Hasin, from .Montreal Island to Lake Teiiiiscaniing. The.se lists have been carefully prej)ared. but are deemed rather voln- minous, and accordingly a synopsis of the leading paheontological ch. ■ iicter.s of the various formations included in the basin are presented, in the hope that they will serve to illustrate the faunas which existed in those old Paheozoic seas. It is by no means exhaustive, but will include the leading, best known and more truly characteristic sjiecies. The geological formations included in the term Ottawa Pahco/.oic Basin, from which fossil organic remains have been obtained, comprise the following, in ascending order : — . I. Potsdam, II. Calciferous, III. Chazy, IV. Bird's Eye and Black Eiver, V. Trenton, VI. Utica, VII. Lorraine, or " Hudson Eiver " of some geologists. VIII. Niagara. 152 ROYAL SOCIETY OF CANADA Of iIk's.. tlR.

The Cha/y Formation. The fauna of the Chazy is readily distinguished from that of the Calcilerous formation, and corresponds to the nature and conditions of sedimentation in tho.se early Ordovician times. The lower beds of the Chazy are arenaceous, and hold the characteristic fossil Scolithus, prob- ably a new (orm, in great abundance, also an extensive series of tracks and trails of murine organisms, some of which may have been made bv gasteroi.oda, some by trilobites, others by annelids, and othera by various other groups of molluscs.
