Figures 32-34. — Structural details of two species of Cambarincola. 32, C. shoshone, new 

 species, body profile, drawn to same scale as next figure to show difference between 

 the smallest and largest species in the genus. 33, C. ingens, new species, body in 

 lateral aspect, paratype, Giles Co., Virginia; 34, reproductive systems of the same 

 specimen. 



Woodhead (1950) has published a figure of a branchiobdellid from 

 Michigan identified by him as vitrea, but it is obvious that his species 

 is not even congeneric with Ellis's. 



Ellis emphasized a superficial resemblence in body form between 

 vitrea and Xironodrilus jormosus , in which I concur. He also pointed 

 out, correctly, the distinctive characters of the small, acutely toothed 

 jaws, but curiously enough one of his paratypes from Douglas Lake 

 is a perfectly typical specimen of the new species C. mesochorea, having 

 jaws entirely different in size and shape from the other specimens of 

 the type series! 



The name vitrea was given by EUis with reference to the glassy 

 appearance of the body wall of the type material. This may be a 

 characteristic of the species in life, but in the preserved specimens 

 which I have seen there is nothing unusual about the texture of the 

 integument.
