mouth or on tongue. Tongue broad, smooth and little free 
in mouth. Two large nasal cavities on side of snout in front 
of eye near together, and nasal barbel originating on frenum 
between. Nasal barbel about equal to ventral or reaching for 
about first */, of length of head. Maxillary barbel rather thick 
at first and reaching about first third of depressed pectoral. 
Outer mental barbel nearly as long. Inner mental barbel a 
little over half length of outer. Interorbital space flattened. 
Occipital process not forming a complete bony bridge to 
spinous process of dorsal. 
Gill-openings inferior, well separated by a broad isthmus, 
and extending forward about opposite to eye. Rakers about 
1 + 7, slender, pointed, moderately long, and much shorter 
than filaments. Branchiostegals 7, upper clavate. 
Skin smooth, on head and along lateral line more or less 
papillate, especially former anteriorly. Lateral line complete 
and median in depth of body along side. 
First dorsal inserted about first third of total length of fish, 
spine robust and about */, of its own length when combined 
with adipose-like prolongation, and smooth. When depressed 
it reaches about */, of space to origin of adipose fin. Adipose 
fin large, rather high, and its base about 1°/, in head. Anal 
high, its origin a trifle in advance of that of adipose fin and 
when depressed its length a little more than that of dorsal. 
Pectoral a little longer than dorsal, and spine robust with 
posterior margin coarsely serrate, with an adipose-like prolon- 
gation. When depressed not quite reaching opposite posterior 
basal margin of dorsal, though beyond origin of ventral. 
Ventral not quite reaching origin of anal. Vent well forward 
or close behind roots of ventrals. 
Color in arrack dusky-brown, forming about five blotches 
transversely on body, and mostly above. First included in 
head, second below dorsal, third below adipose fin, fourth on 
caudal peduncle at base of caudal and fifth on caudal distally. 
These all connected along middle of side of body by isthmi 
of same color. Dorsal dusky-brown. Adipose fin largely dusky- 
brown. Adipose fin largely dusky-brown. Caudal except as 
noted whitish, and tip of each lobe same. Ventral and anal 
whitish, except a small dusky blotch on each medianly. 
Pectoral with spine whitish, fin otherwise dusky. Lower surface 
of body, including head and abdomen principally, whitish.
