877. CHAULIODUS SLOANEI, Bloch k. Schneirtor. 



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 i length of body ; ijectoral 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. (Giinther.) Mediterranean

 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. slotutei,
