Bl 
Head, except occiput, naked; scales on occiput cycloid; those on 
bod}^ ctenoid, large and very regular; 5 lateral series on caudal peduncle; 
scales on breast anterior to the ventrals small, concealed in the thick 
epidermis. 
Dorsal fins well separated, short; height of longest dorsal spine al)out 
equal to postorbital part of head; depressed spines not reaching the rays; 
dorsal rays a little longer than the spines; anal inserted below })ase of 
second or third ray of soft dorsal; rays equal in height to those of dorsal; 
both tins when depressed extending an equal distance posteriorly, their 
tips separated from bases of caudal rays a distance equal to length of 
snout. Caudal rounded, almost truncate. Pectoral acutely roiuided, 
extending to a vertical through vent; upper rays without filamentous 
appendages. Ventrals long, not reaching vent, free posteriorly. 
Color in spirits, pale olive gray; the sides with 6 conspicuous brown- 
ish black spots, the first and smallest at angle of opercle, the last at 
base of caudal; each spot, except the first and last, is connected with 
the one on the opposite side by 2 tolerably well-defined dark l^ands 
passing over the back; a narrow dusky band extending forward from 
eye parallel with dorsal outline of snout; cheek with wavy, oblique 
})ars; occipital region with small, closely crowded blotches. Dorsal 
fins with dusky spots arranged in longitudinal rows; 3 rows on the 
first and 4 on the second fin, the outer row being very indistinct. 
Anal slightly tinged with dusky posteriorly. Caudal with a few very 
indistinct vertical wavy bands. Pectoral with a trace of dusky. Ven-
