origin; predorsal scales 18, snout 4 in head; eye 3|; maxillary 3j; 

 interorbital 2|; second simple dorsal ray 1|; second simple anal 

 ray ll; pectoral 1^; ventral 1^; least depth of caudal peduncle 

 2j; upper caudal lobe 1. 



Body well compressed, edges rounded, deepest at dorsal origin. 

 Caudal peduncle compressed, least depth 1| its length. 



Head conic, moderately compressed, flattened sides moderately 

 approximated below. Snout wide, conic, length f its width. Eye 

 large, advanced, hind pupil edge nearly midway in head length. 

 Mouth moderate, oblique, jaws even. Maxillary largely concealed, 

 reaches eye. Premaxillaries protractile. Jaw edges moderately 

 trenchant. Lips narrow. Mandible rather shallow and rami little 

 elevated inside mouth. Nostrils together, near last f in snout. 

 Interorbital broadly and evenly convex. 



Gill-opening forward about opposite front pupil edge. Rakers 

 small, weak, obsolete or scarcely evident. Filaments about half of 

 eye. Isthmus narrow, especially forward, where frenum narrow. 

 Pharyngeal teeth 5-4, well hooked, and broad grinding surfaces 

 entire. 



Scales large, well exposed, more or less uniform on trunk and 

 smaller on caudal base, belly and breast. Scales cycloid; basal 

 radiating striae 9; circuli rather coarse, 16 to 20, weak and obsolete 

 apically. Scales disposed in longitudinal rows parallel with 1. 1., 

 which continuous to caudal base and well decurved forward; small 

 tubes simple. 



Dorsal origin about midway between hind eye edge and caudal 

 base, second simple ray longest. Anal rather well developed, like 

 dorsal, inserted little nearer caudal base than pectoral origin. Cau- 

 dal moderate, emarginate behind. Pectoral moderate, not quite 

 reaching ventral. Last inserted well before dorsal, reaches anal. 

 Vent close before anal. 



Color in alcohol faded dull brown, paler or whitish below. Dark 

 lateral band begins at snout tip and extends to caudal base, and on 

 sides forward expanded until much wider than eye. Fins all pale, 

 ventral and anal slightly whitish. Dorsal with dusky blotch for- 

 ward near base. Lateral dark band ends in dusky blotch at caudal 

 base size of pupil, which reflected out on median caudal rays basally. 

 Along back pale longitudinal line separates color from back above. 



Length 36 mm.
