Very common in the Bering Sea to depths of 25 to 104 meters (less often to 

 130 meters) . Usually found on rocky or gravel bottoms and in a wide range of 

 temperatures -1.7° to 3.8° (usually a little above 0°). In the Chukchi Sea rare-- 

 among my material (DALNEVOSTOTCHNIK, 1932 and KRASNOARMEIETZ, 1933) 

 we found only one young from Cape Unimark . The considerable material available 

 shows much variation in the snout, depth of the caudal peduncle, number of lateral 

 folds and in a number of other characters. Among variations of this species I
