Macrourus cinereus Gilbert, Kept. U. S. Fish Comm., 1S93 (1890), p. 457. — 

 Jordan and Gilbert, Kept. Fur Seal Invest., vol. 3, 1898, ]). 487.— Gil-

Two specimens, dredged in 510 fathoms off the southeastern coast 

 of Sagkalin Island at Albatross station 5015, extend the southern 

 range of this species from Kamchatka. C. cinereus is an abundant 

 species in Bering Sea, and comparison of the Japanese specimens 

 with material from Bering Sea has disclosed no constant differences. 



The number of radiating ridges on the strong median rostral 

 tubercle varies from 6 to 10, each ridge being composed of stiff 

 spinides; the tubercle is flat, the lower half vertical, the upper half 

 oblique. 



Pyloric caeca much shorter than the orbit, 5 to 7 in number, as 

 counted on the two Japanese and three Alaskan specimens. 



The distance between the ventral base and the anus is about nine- 

 tenths the distance from the ventral base to the isthmus, which is 

 about equal to the postorbital length of the head. 



The following measurements illustrate the large variation in the 

 length of the filamentous outer ventral ray.
