Postorbital: distance ii. 7-1 3.3. 

 Maxillary: length 15.2— 17.3. 

 Mandible: length 15— 17.2. 

 Anal fin: length of base 13.7— 15.3. 

 Pectoral fin: length 12.2— 14.2. 



Scales: ca. 40—44. 



Gill rakers: 19—23+24—28 (most fre- 

 quently 19—21+ 26 or 27). 



Fin rays : dorsal 12—15; ^"^^ 15-18; pec- 

 toral 14—16. 



Vertebrae: 42—44 (7 specimens). 



Body not strongly compressed, its depth S-S~^-S '^^ ^L. Head 3.9—4.3 in SL, its 

 depth slightly exceeding its postorbital length. Snout much shorter than eye, extending 

 about half of its length beyond mandible, 4.2-5.75 in head. Eye 3.25-4.0 in head, 1.6-

2.0 in postorbital length of head. Postorbital i. 9-2.1 in head. Maxillary slightly 

 expanded and rounded distally, generally extending about an eye's diameter beyond 

 rim of orbit, failing to reach joint of mandible by nearly diameter of pupil, i. 4-1. 55 

 in head. Mandible 1.4— 1.66. Cheek slightly longer than eye, its posterior angle about 

 60°. Gill rakers shorter than eye, broad, not close-set, with short coarse serrations 

 on inner edge. 



Dorsal fin with longest rays reaching to, or more usually beyond, tip of last ray if 

 deflexed, its origin variable, most frequently equidistant between caudal base and tip 

 of snout. Anal originating under or slightly behind base of last dorsal ray, its base 6.^— 

 7.25 in SL. Pelvic inserted nearly an eye's diameter in advance of dorsal and about 

 equidistant between base of pectoral and anal origin, reaching much less than halfway 

 to anal. Pectoral failing to reach pelvic base by about an eye's diameter, 1.7—2.0 in 

 head. Axillary scale of pectoral narrow, failing to reach tip of fin by less than dia- 

 meter of pupil, 1.9-2.3 in head. 



Color. In alcohol, pale. Sides of head silvery. Silvery lateral band distinct, generally 

 nearly as broad as eye; some specimens with dusky punctulations on back extending 

 onto caudal fin. 



Size. A total length of about 105 mm (4.2 in.) is attained. 



Variation. Certain poorly preserved specimens from Melbourne Beach, Key West, 

 Tortugas, and Pensacola, Florida, in the Study Material above, appear to be more or
