thalma; gill rakers 80; scutes 20 + 14 or 15; vertebrae 46; teeth on tongue and 

 palatines similar to those in the other species, but weaker. 



Three fish, each about 75 mm. long, were included in refuse from the Bird 

 Key tern rookery; 6, 50 to 63 mm. long, were seined at Long Key or at Garden 

 Key, with Harengula, ]en\insia, and Anchoviella, and had scutes 18 to 20 + 14 

 or 15, gill rakers 48 to 53, vertebrae 45 to 47; and scores of colorless young, up to 

 32 mm. in length, with 22 or 23 gill rakers and 46 or 47 vertebrae, caught about a 

 night light in Bird Key harbor, are believed to be of this species.

Harengula Cuvier and Valenciennes, 1847 



The West Indian species of this genus are two, though for nearly a century 

 more have commonly been recognized. 



Key to the Species 

 a. Compressed, greatest thickness contained 2.2 to 2.7 times in depth; 

 scales adherent; eye moderate, in diameter not exceeding its vertical 

 distance above ventral contour of head; gill rakers 29 to 36; ventral 



scutes usually 17 -f- 14; vertebrae 41 to 43 macrophthalma 



aa. Less compressed, greatest thickness contained about 2.2 times in 

 greatest depth; scales only moderately adherent; eye large, its diam- 

 eter exceeding its vertical distance above ventral outline of head; gill 

 rakers 27 to 29; ventral scutes usually 17 + 10; vertebrae 40 . . . maculosa
