TWO NEW COTTID FISHES FROM THE WESTERN PACIFIC, 

 WITH A REVISION OF THE GENUS STLENGIS JORDAN 

 AND STARKS 



By Rolf L. Bolin 



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



The extensive collections made by the United States Bureau of 

 Fisheries steamer Albatross in the northwestern Pacific during the 

 cruise of 1906 contain several new species of cottid fishes, two of 

 which are herein described. The drawings for the plate were made 

 by the late William Sackston Atkinson under the direction of the 

 late Dr. Charles Henry Gilbert. The text figures of scales were 

 drawn by me. I am greatly indebted to Dr. George S. Myers, of 

 the United States National Museum, for detailed information con- 

 cerning the type and only known specimen of Stlengis osensis. 



In their review of the Cottidae of Japan, Jordan and Starks ^ 

 described two rather closely related species under the names Stlengis 

 osensis and Schmidtia misakia. The two new genera to which these 

 fishes were allocated were distinguished from each other by the 

 character of the squamation alone, there being three longitudinal 

 scale bands in Stlengis and one in Schmidtia. Stlengis distoechus, the 

 new species described below, is an intermediate form having two 

 bands of scales. 



While the three fishes show marked differences in squamation, the 

 strong tendency to reduce and modify scales, which is expressed by
