"' In every cold stream of northern Europe, nortliern .\sia, and northern America species of thi.s perms 

 abound, hirkinp on the bottom and devouring the egns of trout which inhabit the sanio waters. The 

 species are ill difTerentiated and like those of trout subject to much individual variation. Those of the 

 t'nited .<tate-s and Canada are not yet well known and the number of s[)ccies has probalily been unduly 

 expanded Efforts to subdivide the groui) have not been very successful and we place allthc .\uioricnti 

 forms in a single genus, C'ollnx. Western species, allies of C'nthis nsper, termed Cottop.iin , are in general 

 larger in size, more prickly, with well-developed palatine teeth and the ventral rays I, 4. Those of the 

 middle west allied to Cnttim bairdi, called /'otamncnltiix, show similar characters but are for the most part 

 smaller anrl smoother, the colors more mottled. Rafinesfpie's I'cqeilirtit ictnlopx, the "Cat's-eye Spring 

 fish," seems to us a CnltuH described rarelcssly or more likely from memory. In New England and south 

 to Pennsylvania the allies of Cnttiif gracilli called Uranidea are small, smooth, without palatine teeth and 

 the ventral rays I, .'!. Hut all these traits are subject to interi;rading. A few species in dcper waters in 

 Lake .Michigan and f'anada. allies of CMnx ricei called Taiirilea, are more or less rou^ii and liuve the 

 preoijcrculur spine larger, huukeU and somewhat spiral, otherwise much as in C'uUopain.
