 the following i)oints: The skin was only sparsely j)rovided with straight si)ineh'ts 
 .anteriorly, but this was considered to bi- due to the coinparatively pnc.r state of

 trout; lake at Hernard harbour. C.V.E. Station oOg, April, 19Ui. 
 
 Only one specimen was found in the material from Station HOi/, which other- 
 wise belonged to Aliothriiini cnismiin. Kchinorlnjuchns naliiliiii and K. vorrgoiii. 
 and, while unihnibtedly belonging to f. amcriranus, was in many n.-spects much 
 larger than any of those formerly studied. Consequently I submit the above 
 partly emended specific diagnosis to cover this case. The most striking anatom- 
 ical feature presentecl by this si)eeimen is the comp.'iratively large sphinet<'r 
 muscle surrounding the aperture of the fen:ale genital atrium, a structure which 
 1 have also been a' '.<• to find on re-examination of the material upon which the 
 original description of the species was based.

 Specific diagno-iis. With the characters of the genus. Small cestoiles up 
 to .")0 mm. in length and 2-8 in width. Scolex almost spherical, 0-4S to 0-72 
 mm. hmg. ()-.">0 to 0!S4 wid(^ and 0-GO to 1-0 thick. Hothria heinijpherieal, 
 their apertures ordinarily not fused to form a single terminal opening. Stiobiht 
 uniform in width fr(jm a short distance behind the scolex to the po.«terior end; 
 0-4 to 0-G mm. in thickness; slightly more convex ventrally than dorsally. 
 
 Cuticula, ") to 10m ill thickness. Nerve strands 12 to 20^ in diameter; 
 each divides into two branches sagitally before entering the scolex; transverse 
 commissure diffuse. Four main excretory trunks in ripe proidottides. six farther 
 forward passing into the scolex; all in the medullary parenchyma. 
 
 Reproductive organs begin 0-3 to 1-5 mm. from the scolex; ;ip to 1(50 in 
 number. Weak sphincter around the common female cloaca. \ agina opens 
 close behind the uterine pore which is not quite in the median line.
