NEW COTTID FISHES FROM JAPAN AND BERING SEA 



By Rolf L. Bolin 



HopTcins Marine Station of Stanford University, Pacific Grove, Calif. 



Among the cottid fishes collected by the United States Bureau of 

 Fisheries steamer Alhatross, and kindly submitted to me for study by 

 Dr. G. S. Myers, of the United States National Museum, are three 

 new forms obtained during the cruise of 1906. The figures of these 

 were drawn by the late William S. Atkinson under the direction of 

 the late Dr. Charles Henry Gilbert. The fourth new cottid described 

 herein was taken by the Albatross in Bering Sea in 1900.

 so great a degree of relationship to the type species that I choose to 

 include it in this genus. At the same time, the dissimilarities are so 

 marked that it seems advisable to establish a new subgenus for its 

 reception and to recharacterize the genus itself. 



Description. — Head and body compressed throughout, deepest un- 

 der anterior third of first dorsal. Maxillary extending to slightly 

 beyond posterior margin of pupil. Anterior and posterior nostrils 

 both in short tubes about 0.5 as long as nasal spines. Four shorty

 spine directed upward and backward, second spine backward and
