Head 2i; depth 2^; D. X, 13 ; A. Ill, 8 ; P. ii, 14 ; V. I, 5 ; scales 50 in a 

 lateral series to base of caudal below lateral line ; 9 scales in a slightly oblique 

 forward series between origin of spinous dorsal and lateral line, and 17 between 

 latter and origin of anal; pores 49 in lateral line to base of caudal; width of head 

 2|- in its length ; depth of head at posterior margin of eye 1^; mandible 2; third 

 dorsal spine 2|; tenth 3^; fifth dorsal ray 2|-; second anal spine 31; first anal ray 

 2-|-; least depth of caudal peduncle 3-1- ; upper caudal lobe 1^; pectoral 1\; ventral 

 1|- ; snout 2 y'lj, from tip of upper jaw ; eye 4-1- ; maxillary 2|- ; interorbital space 5|-. 



Body elongate, compressed, rather slender, and back somewhat elevated, with 

 a more or less curved profile. Caudal peduncle compressed, and its least depth about 

 one and one-quarter in its length. 



Head elongate, pointed, compressed, and upper profile straight from tip of upper 

 jaw to occiput, though well inclined. Snout rather long, convex, profile straight, 

 and upper jaw projecting. Preorbital a little less in width than vertical diameter 

 of eye. Eye a little longer than deep, a little anterior, and high in head. Mouth 

 rather small, slightly inclined horizontally, and curved. Lips thick, rather broad, 

 fleshy, and papillose on their inner edges. Lower jaw projects well beyond upper. 

 Maxillary reaching a trifle bej-ond front of eye, and its distal expanded extremity 

 one and three-quarters in horizontal diameter of orbit. A narrow inner series of 

 fine teeth in jaws, but only in front of lower. An outer series of enlarged sharp 

 pointed conic teeth in each jaw, those on sides and front of mandible enlarged, and 

 a pair of large canines in upper well separated. Minute teeth on vomer, palatines, 

 and tongue, in a V-shaped patch on former. Tongue rather long, rounded, and free 

 in front. Nostrils well separated, anterior with a slightly elevated fleshy rim, much 

 nearer front of eye than tip of snout, and posterior about midway between front of 

 eye and anterior. Interorbital space a trifle convex. Margin of preopercle finely 

 serrated, with a slight excavation below opposite rather obsolete interopcrcular 

 process. Opercle with two broad processes. Opercular flap rather obtuse. 



Gill-opening extending forward nearly opposite posterior nostril. Gill-rakers
