lateral line to soft dorsal origin, 8 below to spinous anal origin; 6 pre- 
dorsal scales; head width 2^ in its length; head depth at occiput 1^; 
snout 4|; eye 3; ma.xillary 2; interorbital 4|; third dorsal spine 3;

Body moderately deep, compressed, deepest at spinous dorsal origin, 
back not elevated, and edges rounded. Caudal peduncle compressed, 
least depth about 1^ its length. 
Head large, elongate, well compressed, surfaces evenly sloping above 
and below, lower profile more inclined than upper, which is nearly 
straight from snout to spinous dorsal origin. Snout short, surface 
convex, length about f its width. Eye large, circular, close to upper 
profile, and center near first | in head length. Mouth large, well 
inclined, and lower jaw slightly included when jaws close. Maxil- 
lary large, well inclined, slightly curved up, and reaches about oppo-

Teeth in bands in jaws, small, short, simple, and even. Narrow row

side of snout above, anterior near middle of its length, and posterior 
close before eye. Interorbital depressed, or very slightly concave. 
Hind preopercle edge finely serrate, though several serrations just 
above angle slightly enlarged. Opercle with single small spine.
