Genus OLIGOPLITES Gill 



Leatherjackets 



Oligoplites Gill, Proc. Acad. Nat. Sci. Philadelphia, 1863, p. 166. (Genotype, 

 Oligoplites inornatus Gill.) 



In an attempt to determine what name should be applied to the 

 Oligoplites inhabiting Lago de Maracaibo I made a study of nearly all 

 the specimens of this genus in the United States National Museum. 

 My results were pubhshed (Schultz, 1945d) and it is not deemed 

 necessary to repeat them here. In all, seven species were recognized, 

 three in the Atlantic and four in the Pacific, all in American waters. 



KEY TO THE SPECIES OF OLIGOPLITES FROM THE WESTERN ATLANTIC 



la. Number of gill rakers on first arch, including rudiments, 5 to 7 + 16 to 20;

 front of snout: teeth on dentary in two distinct rows; dorsal rays IV-I, 20 or 

 21; depth 3 to 3.4; head 1.3 in young, 1.4 to 1.6 in adults; posterior margin
