of the fin is very oblique and is about equal to length of caudal pedun- 

 cle ; distance from origin of anal to base of caudal, 2 in distance to tip 

 of snout ; longest anal ray 1^ in head. Caudal broad, 1^ in head. Ven- 

 trals (in ^) reaching anal, 2^ in head. Pectorals long, reaching mid- 

 dle of ventrals, IJ in head. Oviduct not adnate to first anal ray. 



Female specimens have body less deep, fins much lower, and differ- 

 ent coloration ; the depth is 2f to 2| in length, and the longest dorsal 

 ray If in head. 



Head 2-,\ in length ; depth 2 ; D. 9 or 10 j A. 11 or 12 ; V. G ; P. 14 ; 

 B. 5 ; scales 25-10. 



Color: ^, dark green, sides with 10 to 14 narrow bands of bluish- 

 silvery, the first of which is somewhat in front of dorsal; these bands 

 are slightly oblique below, and are a little narrower than the interspaces ; 

 they become wider and farther apart behind ; the interspaces are fre- 

 quently divided by fainter silvery bands; a diffuse, broad, dusky blotch 

 below and behind eye. Lower jaw bright orange; lower side of head 

 and belly yellow.

 Fpots, and sometimes most of them, orange ; anal similarly colored ; 

 caudal wiMi irregular alternately darii; and light bars, and a few white 

 basal spots ; ventrals dusky, tipped with sul[>hur-yellow ; pectoral trans- 

 lucent.

 obtained from the Laguna Grande, at Pensacola, in salt-water.

 and rather slender, its greatest height If in head, its length slightly 

 less than head; mouth very small, ])rotractile forwards, the lower jaw 

 very much projecting in open mouth ; mandible heavy, short, and 

 strongly convex, less than diameter of orbit; teeth small, but firm and 

 strong, conical, in a single series in each jaw, or forming an irregular 

 double series anteriorly; no villiform teeth behind this outer series; 

 eye large, 3 in head, slightly shorter than interorbital width, and greater 

 than length of snout. 



Intestinal canal rather less tlian length of body.
