Body elono-ate; compressed. Head laro-o; the snout notaldy short 
and ))lunt anteriorly. Eyes small; hi^-h in head; their upper edges 
})rojecting a))ove the dorsal contour; interorbital space very narrow;

Head naked except on upper edge of opercle and on occiput. Body 
with very small cycloid scales. 
Spinous dorsal long and high, the spines var^nng in munber from 
12 to 16; higher anteriorly, growing gradually shorter posteriorly; 
when depressed not reaching insertion of soft dorsal. Kays of soft 
dorsal of about the .same length throughout. Anal inserted on a ver- 
tical passing a little anterior to insertion of soft dorsal, its rays when 
depressed not reaching so far Ywsteriorly as do those of dorsal, both 
falling far short of l)ase of caudal. Pectorals and caudal rounded. 
Ventrals short; partially united l)y a ver}^ thin mem))rane. 
Color in spirits brownish; darker above than below; small dark 
specks scattered over sides and u})per parts. Color of spinous dorsal
