tubular scales 29 in upper arch of lateral line aud 15 pores in hori- 
zontal section, of which last one on caudal base; 47 scales between 
suprascapula and caudal base; 7 scales above lateral line to spinous 
dorsal origin, 13 below to spinous anal origin; 18 predorsal scales; 
head width, 1% in its length; head depth about equals its length; 
snout, 44; eye, 3; maxillary, 24; interorbital, 3; first dorsal spine, 
32; tenth, 2; fourth dorsal ray, 13; second anal spine, 24; fifth anal 
ray, 2; least depth of caudal peduncle, 24; caudal, 1; pectoral, 14; 
ventral, 14. 
Body elongately ellipsoid, deepest about midway in its length, well 
compressed and edges convexly rounded. Caudal peduncle well com- 
pressed and least depth about equals its length. 
Head moderate, rather robust, well compressed, flattened sides 
very slightly converging below, profiles ahke. Snout convex over 
surface and in profile, length three-fifths its width. Eye large, cir- 
cular, little elevated and hind pupil edge nearly midway in head 
length. Mouth moderately wide, gape short, oblique, closed jaws 
about even. Lips fleshy, rather narrow. Maxillary large, well in- 
clined and exposed, reaches well beyond front eye edge, only narrow 
upper edge slipping below little differentiated preorbital. Teeth 
moderately small, uniserial, somewhat compressed, pointed and not 
forming cutting edge, also slightly larger in front of jaws. Greater 
portion of maxillary edge with finer similar teeth. No teeth on 
mouth roof or tongue. Inner buccal folds moderately wide. Tongue 
depressed, moderate, free. Nostril small pore little behind middle 
in eye. Pseudobranchiae slightly less than gill-filaments. Branchi- 
narrow, width little less than that of maxillary. Hind preopercle 
edge roughly serrate. Opercle with two spines, lower little more 
backward. 
Gill-opening extends forward about opposite front eye edge. Gill- 
rakers, 8-+-19, lanceolate, slightly shorter than gill-filaments or 24 
in eye. Pseudobranchiae slightly less than gill-filaments. Branchi- 
ostegal membrane short, forms very short fold across narrow con- 
stricted isthmus. 
Scales finely ctenoid, become little smaller about body edges and 
in lengthwise rows parallel with lateral line. All larger scales rather
