Habitat. Atlantic and Pacific coasts of tropical America, and 

 the West Indies (Cape San Lucas ; San Domingo ; Jamaica ;

 lan; Key West). 



The numerous specimens examined by us are from Havana and 

 Key West, and range from 1 to 7^ inches in length. Head 3^ ; 

 depth 2f to 2| ; scales 5-45-9 ; Dorsal IX-10 ; A. Ill-t. 



Body elliptical, compressed, back moderately elevated ; anterior 

 profile little convex, not very steep ; snout rather pointed, mouth 

 moderate, maxillary reaching almost to vertical from front of 

 orbit, its length 3 in length of head ; exposed portion of maxil- 

 lary triangular in front, oblong behind, its width 2 in its length, 

 which is 4| in length of head. Preorbital and preopercle entire. 

 Eye not very large, its diameter 3^ in length of head, snout 3i in 

 head. Premaxillary groove long, linear, and naked, Gill-rakers 

 small and weak, t below the angle. 



Dorsal spines weak and flexible, the longest 4| to 2y^o in head ; 

 anal spines rather short, the second the stronger, its length 3^ in 

 length of head ; ventral fins short, their tips reaching about half- 

 way to anal, their length If in head. 



Pectorals slender, their tips reaching about to vent; length of 

 pectorals about equal to head ; ventrals and caudal mostly covered 

 with small scales ; other fins naked, color in life silver}', greenish 

 above ; snout and upper part of caudal dusky ; spinous dorsal 

 punctate at base, usually abruptly black at tip ; the dark areas 

 are separated by a transparent horizontal bar (these markings 

 wanting in some specimens, perhaps females); soft dorsal punc- 

 tate ; caudal with a faint dusky margin ; ventrals pale. 



This species is very common at Kej' West and Havana. There 

 seems to be no difference between the " harengulus " of the East 

 Coast and the West Coast ^'gracilisy
