 distinct dark vertical l)liitches, one under spinous dorsal, 2 under soft dorsal and 1 on caudal peduncle; 

 under parts yellowish-white, profusely covered with minute Ijrown punctulations; spinous dorsal dusky, 

 each ray with 1 or 2 black spots, the eighth spine almost entirely black, edge of fin creamy white; soft 

 dorsal dusky, with numerous irregular black blotches, the edge somewhat creamy; anal pale, punctate' 

 with dark; caudal yellowish-white, crossed by 4 or 5 irregular, dark, vertical bars; pectoral similar to

 seen from an examination of the following table;

This species seems to be related to Cottus bddingi and to Cottus spilotus. From the former it may be 

 distinguished by the much larger eye, the nan-ower interorbital. the blunter head, the fewer anal rays, 

 and the coloration; from Cottus sjnlolus it would seem to differ in the shorter anal, the more complete 

 lateral line, in coloration and in other respects. 



The collection contains217specimens,w-hichwe refer to this species. They vary in length from less 

 than 1 inch to 2.9 inches. The collector's label, which should have accompanied these specimens, 

 has been lost, but it is certain that they came from fresh water at Loring. Alaska, and that they were 

 collected by Mr. F. M. Chamberlain in 1903.

We take pleasure in naming this .species for our friend and associate, Mr. Fred. M. Chamberlain, 

 naturalist of the steamer Albatross, wlio collected the type.
