This species is full}' described by Mr. Cramer in Jordan and Eyer- 

 mann\s work. 



A large dried specimen lOi inches long was found at Hakodate, and 

 three smaller ones were loaned by the Sapporo Museum, taken at 

 Tomakomaki, near Mororan. They agree yery well with a specimen 

 from Iturup Island, from which Cramers description was made, 

 except that they show a greater yariation in fin rays. The specimen 

 from Hakodate has the dorsal rays VIII, 8; and the anal, 13. • The 

 other three are as follows: Dorsal IX, 7; anal, 11; dorsal VIII, 7; 

 anal, 12; dorsal IX, 8; anal, 13.

 a beak, but because its head and snout are more contracted than in 

 the others.")
