except a slight depression on snout; snout bluntly rounded, lower jaw included; mouth moderate, 
horizontal; a single row of wide-set, small, conic teeth in each jaw, none on vomer or palatines; 
maxillary not reaching vertical from eye by a distance equal to three-fourths diameter of eye; barbels 
included; maxillary 2.33 in head, terminating between the nostrils; strong, blunt, but conical teeth 
in one series in each jaw, the teeth more or less widely separated; eye 2.75 in snout and 5 in 
head; interorbital space very convex, 3.66 in head; preopercle with upright limb slanting obliquely 
forwards; opercular spine strong; gillrakers 2 in eye, 4.5 in maxillary, about 28 on lower limb of 
arch; barbels two-thirds length of head, reaching posterior margin of subopercle; scales large, 
ctenoid; dorsal fins well developed, third and fourth spines longest, 1.33 in head, twice the height 
of soft dorsal, the last rays of which are scarcely longer than the first; soft dorsal two-thirds as high as. 
long, its length 2 in head; caudal moderate, well forked, upper lobe more rounding, 1.37 in head; 
anal differs from soft dorsal in having its first, branched rays one-fourth longer than the last, the 
unbranched ray also slightly exceeding the last ray; the greatest height of the fin 2.6 in head; 
the membrane of the first soft ray envelops a small spine, which, being thus covered, might 
easily be overlooked; the first articulate ray of anal, as in soft dorsal, not branched; ventral fins 
large, 1.33 in head, about reaching tip of pectoral; air-bladder large. 
Color in spirits, olivaceous, lighter below, the fish as a whole having a smutty appearance; 
exposed part of each scale punctulate with brown; first dorsal and caudal dusky; base of soft dorsal 
dusky, upper half irregularly light and dark; anal with irregular dusky bars; soft dorsal, caudal, and 
anal tipped with black; ventrals yellowish, spine and connecting membrane smutty; pectorals yellow, 
their base, the preorbital, and upper part of head purple; barbels very dark; branchiostegal membrane
