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 2 / 3 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 3 / 5 of its own length when combined 

 with adipose-like prolongation, and smooth. When depressed 

 it reaches about 3 / 4 of space to origin of adipose fin. Adipose 

 fin large, rather high, and its base about i 3 / 5 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 proloa- 

 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.
