Top of head to middle of eyes, opercles and upper part 
of preopercles closely covered with small rough scales; 
head otherwise naked; body above lateral line completely 
covered with ctenoid scales, not very regular in size, ar- 
ranged in about 67 series; lower half of body covered to 
within a short distance of anal with about 50 oblique plate- 
like folds of skin, the posterior edges of which are finely 
and sharply serrate, the pores of lateral line are situated 
in the upper end of these folds; pectoral base, belly and 
a narrow space along base of anal, naked; fins, with the 
exception of pectoral, which has a few rough scales on 
the rays, naked. 
Dorsal spines slender, the first one inserted in advance 
of pectoral base, directly over the upper end of gill-open- 
ing, the fin somewhat round in outline, the spines not va- 
rying greatly in length, with the exception of two or three 
on each side; soft dorsal a little lower than spinous, the 
rays subequal, its base is a little shorter than the base of 
first dorsal, and slightly longer than the length of head; 
ventral fins long, their tips reaching past front of anal fin, 
their length equal to the distance from snout to edge of 
preopercle, the pubic bone very prominent; pectoral fins 
long and curved upward, the middle rays the longest, 
reaching far past tips of ventrals and front of anal to the 
space between dorsals; the ends of lower rays free, the 
width of the fin at its base is contained three times in the 
length of the head; caudal rounded. 
Color in spirits blackish, with traces of 4 or 5 darker 
cross-bars on back, sides below lateral line mottled, faint 
dark spots along lateral line, more conspicuous posterior- 
ly; a dark bar half as wide as eye, running from eye 
downward across cheek to anterior end of interopercle; 
bordered on each side by a light streak, a similar bor- 
dered bar running across top of head, slightly turning
