Color bluish above; silvery below; snout and tip of lower jaw dusky; fins mostly more or less

This species is represented in the present collection by a single specimen, 180 millimeters (7 
inches) in length. 
This fish has been recorded only once from Chesapeake Bay, and it was seen only once during 
the present investigation. It is probable that only stragglers enter the bay. The species is reported 
to reach a length of 2 feet. One of us (Hildebrand) observed numerous examples on the coasts of 
Panama, where this fish is common and of some commercial value. The maximum length in that 
vicinity appeared to be only about 15 inches. 
Habitat . — Both coasts of tropical America; stragglers ranging northward on the Atlantic to 
Massachusetts. 
Chesapeake localities. — (a) Previous record: Cape Charles city, Va. ( b ) Specimen in collec- 
tion: Lvnnhaven Roads, Va., taken in a pound net, September 27, 1921.

tongue; lateral line with a long, low arch, unarmed, in a slight keel on caudal peduncle in adult; 
first dorsal with six to eight slender spines/connected by membrane; second dorsal long, more or 
less elevated anteriorly; anal similar to second dorsal, only much shorter; no finlets; ventral fins 
long; pectoral fins broad, shorter than ventrals.
