Trachinotus falcatus (Linnaeus). 



Plate z3-

Head 2% ; depth 1V7; D- I, VI, I, 20, i; A. II, I, 18, i; snout 

 4 in head; eye 3; maxillary 3; interorbital space 2^; fourth 

 dorsal spine 3^; second dorsal ray i^; second anal spine 4; 

 second anal ray i Ys ; lower caudal lobe i ; least depth of caudal 

 peduncle 32/^; pectoral i^ ; ventral 2. Body deep, ovate, well 

 compressed, and upper profile nearly straight from interorbital 

 space to procumbent dorsal spine. Head deep, compressed, and 

 blunt. Snout blunt, short, so that upper profile line of head would 

 form an obtuse angle at front of interorbital space. Eye circu- 

 lar, well anterior. Mouth a little inclined, and upper jaw pro- 

 jecting a little beyond lower. Maxillary reaching in vertical a 

 little beyond front rim of orbit, but not quite to that of pupil. 

 Teeth minute, in bands in jaws. Interorbital space a little con- 

 vex. Gill-rakers 6+12, slender, longest about jA, diameter of 

 pupil. Scales minute and .smooth. Base of first erect dorsal 

 spine about first quarter of pectoral, spines well freed, and fourth 

 longest. Rayed dorsal inserted about midway between posterior 

 margin or orbit and base of caudal, anteriorly elevated with a 

 small lobe. Rayed anal inserted a little beyond origin of rayed 

 dorsal, also with a slight anterior lobe. Second anal spine long- 

 est, joined to third by membrane. Caudal deeply forked, lobes 

 pointed and slender, and lower longer. Pectoral short, reaching 

 base of third anal spine. Ventral inserted a little behind origin 

 of pectoral or a little before that of spinous dorsal. Color silvery-
