Anchovia mundeola. 



87. Anchovia spinifera {Cuvier ct- Valenciennes). 

 Plate VIII, Pig. 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 somewhat 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 extend to or 

 slightly i^ast the middle of the outer ventral rays.
