anchovies (Engraulidae). These small fish apparently are not fully 

 mature. The proportions and enumerations enclosed in parentheses 

 in each instance apply to the type. 



This species is very close to Odontognathus tropicus Hildebrand 

 (U. S. Xat. Mus. Bull. 189, p. 94, fig, 19, 194O), which was dcscrilxrd 

 from specimens collected in the Gulf of Guayaquil, Puerto Pizarro, 

 Peru, and at Balboa, Canal Zone. It was learned from a comparison 

 of the type material of 0. tropicus with the specimens herein described 

 as A^, cubanus that the two species are congeneric. I'ecause tropicus 

 is represented by larger and more mature specimens than cubanus.
