ENGRATJLIDID^]. 

 Anchovia clupeoides (Swainson). 



Santo Domingo 1 ; Rio Seco, Porto Rico 1. These both agree with 

 Swainson's account, though likely Stolephorus surinamensis Bleeker 

 may be different. Engraulis product us Poey is evidently a synonym 

 of the present species. 



ANCHOVIELLA subgen. nov. 

 Type Engraulis perfasciatus Poey. 



This differs from the subgenus Anchovia Jordan and Evermann in 

 the fewer gill-rakers, usually much less than 100 or about 35 to 50. 

 Prof. E. C. Starks has kindly examined the gill-rakers of Anchovia 

 macrolepidota (Kner and Steindachner), the typical species of Anchovia, 

 and finds them about 106 + 135. Anchoviella includes the majority 

 of species of Anchovia. 



(Anchoviella, diminutive of Anchovia, as most of the species are of 

 small size.) 



Anchovia perfasciata (Poey).
