Study Material. Type material, 1 1 specimens, about 33-38 mm TL (caudal fins 

 damaged), all from the Gulf of Venezuela. The specimens probably are not full-

grown, but the maxillary, which is shorter and blunter in very young than in adults, 

 probably has acquired the approximate length and shape of a mature fish. At least it 

 is shorter and much more rounded than in specimens of Anchoa parva and A. mitchilli 

 of similar size. 



Distinctive Characters. The long anal fin, the small number of gill rakers, the short 

 head, and the very short, blunt snout distinguish this species from related forms.
