Plate VIII, Fig. 15. 



Two specimens were taken in shallow water by means of a cast-net. 



Head 4 in length; depth 4; dorsal 16; anal 38; scales 42. Form moderately slender, the 

 dorsal outline ascending in nearly a straight line from snout to front of dorsal, where it reaches the 

 greatest height; thence descending at about the same angle in a straight line to caudal peduncle; ventral 

 outline evenly curved from tip of lower jaw to caudal peduncle. Abdomen somevv hat compressed, 

 not serrated. 



The head is rather long, and has a sharp conical snout. The upper posterior outline of the 

 gill-opening is very oblique. A line drawn from snout to angle of opercle would nearly parallel the 

 oblique maxillary. The subopercle projects beyond the opercle in a triangular process. The eye is 

 placed within the first two-fifths of the head. The maxillary is slender, and not angulated on its upper 

 outline towards its posterior end. It is widest near angle of mouth, and ends in a rather sharp point 

 near lower edge of gill-opening. The teeth are small but sharp. The gill-rakers are slightly shorter 

 than the orbit; about 15+17 in number. 



The origin of the anal is about under the middle of dorsal. The pectorals cxtciul tu or 

 slightly past the middle of the outer ventral rays.
