782(c). STOLEPHORUS NASO, Gilbert & Pierson, new species. 



Head 3.3 to 3.5; depth 4.7 to 5.8; eye 4 to 5 in head. D. 14 or 15; A. 

 22 to 24; lateral line about 35 (?). Dorsal and ventral outlines weakly 

 arched; body slender, its greatest depth 1.5 in head, compressed; belly 

 carinated in front of ventrals, and sometimes behind them in larger speci- 

 mens. Head long and slender, its greatest width 1.5 to 1.7 in its length, 

 the lower profile much more oblique than the upper. Snout long, com- 

 pressed, bluntly rounded, its length exceeding the small eye. Cheek with 

 a very acute posterior angle. Opercle narrow, oblique. Maxillary rather 

 bluntly pointed, failing to reach gill opening by about \ diameter of pupil. 

 Teeth on the maxillary quite prominent and directed forward. Gill 

 rakers short, 17 -f 20 in number, the longest 1.5 in eye. Scales large, thin, 

 deciduous, only a few scattering ones remaining in our specimens. Dorsal 

 fin inserted midway between front or middle of orbit and base of median 

 caudal rays. Origin of anal under or slightly behind middle of dorsal; 

 length of anal base about equal to the distance from front of orbit to base 

 of ventral fin ; pectorals not reaching ventrals, their length about \ length 

 of head. Length of ventrals equaling or slightly exceeding distance from 

 tip of snout to middle of pupil. Color light olive, with the usual bright 

 reflections; a large dark patch of brown dots on occiput; a double series 

 of dots along median line posterior to dorsal, this absent in some speci- 

 mens ; large specimens with a bright, well-defined silvery streak, slightly 

 narrowing anteriorly and on caudal peduncle, its greatest width about 

 equaling diameter of eye ; in the young, this band is fainter and narrower ; 

 a conspicuous series of black dots at base of anal. Characterized by the 

 slender form, well-defined silvery streak, sharply carinated breast, the 

 small eye, and th'e very long, compressed, deep, and rather bluntly rounded 

 snout. Most closely resembling S. starksi, from which it differs in the 

 smaller eye, longer snout, and slightly longer anal. Length 2 to 2 inches. 

 Panama; common. (Gilbert & Pierson.) (naso, long-nosed.)

732(d). STOLEPHORUS STARKSI, Gilbert & Pierson, new species. 



Head 3.3 to 3.6; depth 4.8 to 5.5 in length, 11 in head; eye 3 to 3.5 in 

 head. D. 15 or 16; A. 17 to 22; scales about 41. Body long and slender, 

 slightly deeper and more compressed than in S. ischanus, which much 

 resembles this species. Dorsal outline very little arched; ventral outline 

 nearly straight from gill opening to insertion of anal fin, the lower profile 

 of head oblique, nearly straight. Belly compressed, keeled for anterior 

 f of distance anterior to base of ventrals. Head long and pointed, its 

 width 1 times in its length ; maxillary abruptly widened at the maiidib- 

 ular joint, tapering posteriorly to a blunt point, which reaches almost to 

 the gill opening, its length equal to length of base of anal; snout long, 

 sharp, and projecting, abruptly compressed in its terminal portion as seen 

 from above, its length f diameter of orbit, or slightly more. Branchios- 

 tegal membranes united at base for a very short distance. In 4 exam
