Habitat. — West Indies ; Florida Keys to Brazil. 



Head, 3 (3f ) ; depth, 2f (3i). D. XII, 16. A. IH, 7. Scales 7 or 8- 

 46 to 48-16. Length, 11^ inches. (D. XII, 18, in a second example ; 

 depth, 2| in a third.) 



Body comparatively deep, the back more elevated and more sharply 

 compressed than in any other of our species ', the anterior profile steep 

 and nearly straight from tip of snout to above eye, where a slight angle 

 is formed, the profile thence rising more steeply and forming a somewhat 

 steep curve before the dorsal. In most specimens, especially the 

 larger ones, the concavity above the eye is well marked, not, however, 

 in all. Snout long, pointed, its length 2^ to 2| in head ; ventral outline 

 uearl}^ straight ; caudal peduncle rather long. 



Mouth large, the maxillary extending very nearly to front of eye, its 

 length 2| to 2f in head, lower jaw included. Teeth not very large, in 

 narrow bands, the antrorse teeth of the posterior part of lower jaw less 

 developed than in some other species ; eye small, 5 to 7 in head ; inter- 

 orbital space strongly convex, its width 3f in head ; preorbital deep, its 

 least breadth 4^ in head ; preoi^ercle finely but sharj)ly serrate, the 

 teeth coarser above. In most of the specimens these serrations are dis- 

 tinct, but in one, not otherwise peculiar, they are scarcely distinguisha- 

 ble ; gill-rakers rather small, about 12 below the angle. 



Scales moderate, those above lateral line not enlarged, arranged in 

 very oblique series ; those below more nearly horizontal ; soft parts of 

 dorsal and anal covered with thin translucent scales. 



Dorsal spines rather slender, the fourth highest, about 2} in head ; 

 longest soft rays 5 in head ; caudal lobes subequal, 1^ in head ; anal 

 moderate, its longest rays 4 in head ; second anal spine stronger and 

 longer than third, 3^ in head, reaching past base of the last ray when 

 depressed ; first soft rays when depressed not reaching tips of last 

 rays ; ventrals, 1§ in head ; pectorals, 1^.
