scales margined with darker; sides with 13 to 15 dark cross-bauds of 

 the color of the back, not extending on the belly, but almost reaching 

 lower median line behind ventrals ; these bands usually approximately 

 parallel, and the anterior ones, at least, narrower thau the interspaces, 

 the widest of which is about two-thirds diameter of orbit; sides poste- 

 riorly to origin of dorsal finely speckled with small pearly spots which 

 cover both bands and interspaces. Dorsal and anal margined with 

 orange anteriorly, the color deeper on front of anal; the two fins tinged 

 with orange and checked with black and pearl color ; caudal light orange, 

 indistinctly barred at base with series of linear blotches; pectorals and 

 ventrals plain orange, the former slightly dusky. 



9 dark above, sides finely dusted with darlt points, pale below, tinged 

 with yellowish; middle of sides with about 13 very narrow, short, dark 

 half bars ; back sometimes with small dark blotches ; dorsal dusky with 

 a very distinct black spot ocellated with white, on its posterior rays ; 

 caudal and anal plaiu dusky; ventrals light yellowish. 



About 15 specimens, the longest about 3 inches long, obtained in 

 Laguna Grande, at Pensacola.

Body very deep and much compressed, with very high caudal j^edun- 

 cle, rapidly tapering head, and ver}" slender, sharp, conical suont; tip 

 of snout on axis with body, the ventral outline somewhat more arched 

 than the dorsal ; profile rising rapidly from tip of snout to origin 

 of dorsal, slightly depressed at nape ; body highest at origin of dorsal 

 fin, where the profile is angulated; depth much greater in adults than 

 in the young; in a male specimen, 2 J' long, the depth ennals one half 

 the length; in younger males the depth is contained 2.^- to 2.;V times in 

 length; greatest depth of caudal peduncle 3;? in length. Head high 

 and narrow; snout conical, pointed; jaws equal, the gape horizontal 

 in closed mouth ; mouth protractile downwards and forAvards ; teeth 

 very small, in a villiform band, the outer series in each jaw enlarged 

 and conical. Eye large, 3 in head, 14^ in tlie narrow interorbital si)ace, 

 equal to length of snout, rather more than length of mandible. Branchi- 

 ostegal membranes broadly joined across throat, united as far back as 

 vertical from preopercular margin. Branchiostegal 5. Opercle joined 

 by membrane to shoulder- girdle, down to a point just above base of 

 pectoral. 



Intestinal canal equaling length of body. 



Dorsal in advance of anal, its origin midway between base of caudal 

 and middle of orbit; the fin much higher than long, the longest rays 

 reaching, in adult males, beyond rudimentary caudal rays; highest dor- 

 sal ray If in head. Anal beginning opposite middle of dorsal base, 

 similar to dorsal, but lower, scarcely reaching base of caudal ; the base
