nearer to base of pectorals than to that of ventrals. Dorsal spine 
a little shorter than longest dorsal rays, only its lower half 
bony and roughened behind, its superior half cartilaginous 
and flexible. Height of anterior part of anal a little shorter 
than half head; caudal slightly longer. The first visible caudo- 
dorsal rays emerge about above the middle of the anal from 
a low fat pad, which begins about above the second '/, of the 
anal. Ventrals rounded, reaching on the anal, a little shorter, 
than half head. Pectorals reaching the ventrals, equalling */, 
of the head. Pectoral spine a little shorter than longest rays, 
its distal half cartilaginous and flexible, its lower half bony 
and roughened behind. Anterior half of body with closely set, 
hairlike filaments. On the upper surface of the head they are 
smaller and much more distant. Maxillary teeth in two juxt- 
aposed oval patches, about two times broader than long, 
molarlike, the front series more or less cylindrical and conical. 
Mandibulary teeth molar, in two rounded patches, tapering 
laterally. Vomerine teeth molar, in a triangular patch, the 
rounded top of which is directed forward, its base being con- 
cave. Horizontal branch of first branchial arch with 1g gill- 
rakers, besides 2 very low anterior ones; the freeborder of its 
membrane irregular, anteriorly with independent tubercles.

Height about 7, head 5'/,. Dorsal profile slightly convex 
from dorsal to before eye, snout slightly concave, eye situated 
just behind the middle of the head, very high, near the level 
of the surface of the head, looking upwards, 7—8'/, times in 
head, about 3 times in the convex interorbital space. Lips 
thick, papillated and lamellated, their lateral lobe very pro- 
minent. Nasal barbels reaching the middle of the eye, mandi- 
bulary and maxillary barbels equal, a little longer than nasal
