twice as near to snout as to base of caudal. Ventrals in- 

 serted in front of origin of dorsal. Twelve to 14 upper rays 

 of pectorals produced, reaching first rays of anal or much 

 farther. Anal i' 2 / 3 I 3 /- in length of body, n abdominal keeled 

 spinous scutes, 4 praeventral ones, none of which before pec- 

 torals. About 26 28 gillrakers, as long as the eye. Length 

 140 mm. (Compared with typical specimens of Bleeker in the 

 Leyden Museum).
