Head 7; depth 7. B. 17; D. 6; A. 12; V. 7; scales 56 (65 in a figure 

 published by Agassiz in Cruise of the Blake}. Dorsal not far backward, 

 its distance from occiput less than length of head, its first ray produced 

 in a long filament nearly length of body ; pectoral fins short ; ventral 

 fins long, longer than head, and much longer than pectorals. About 30 

 luminous dots in a series from the chin to the ventrals. Scales of the 

 body subhexagonal. Head nearly as deep as long. Greenish above ; sides 

 silvery; belly blackish. Length 12 inches. (Gftnther.) Mediterranean

Head 6; eye4; snout 4^. D. 6; A. 11; V. 7; P. 13; scales 56. Longest

 of scales, its first ray 3i to 4i in body, its base 3 in head ; base of adipose

 inserted under seventeenth scale of lateral line. Coast of California to 

 British Columbia, in deep water ; the type taken off Queen Charlotte 

 Islands, in 876 fathoms ; about 4 specimens known ; close to C. sloanei, 

 the head a little longer, the scales perhaps larger ; probably not distinct.
