p/n'/o/iips from Field, B. C. It differs from both of these 

 in having the mouth and eyes smaller, and from the Field 

 specimen in having a deeper body. 



Here described from four specimens from 2 l /i to 3^ 

 inches in length, collected at Gypsum, Colorado, from 

 the Eagle River, by Jordan, Evermann, Fesler and Davis, 

 Nos. 1305, 1308, 1309 and 1310, L. S. Jr. Univ. Mus. 

 It has hitherto been confounded with Coitus semiscaber , 

 which was taken in abundance at the same place, and 

 recorded in their report as "Cottus bairdii pitnctulatiis." 

 The species is named for Miss Anna Louise Brown, 

 artist of the Hopkins Laboratory. 



We may here note that Cottus philonips is very doubtfully 

 distinct from Cottics beldingi, the only difference we can 

 find being in the deeper body of the latter, which is a 

 widely distributed species. Of Cottus philonips only the 

 types are yet known, the Alaskan specimens referred to 

 it being quite distinct.
