 and two young 30 and 69 mm. m length, the former from Wakanoura 

 and the latter from Tsuruga. 



Head 2% to 2| in body; depth 2; eye 5^ in head; maxillary 2f; 

 snout 2 J, preorbital width 4; interorbital 4J; D, XI, 15; A. Ill, 9.

 between insertions of dorsal and anal, 11 or 12/20. Gill-rakers 6 + 14. 



Body very deep, mouth very low, nearly in line with ventral
