Height 37,— 47c, head 47,,— 4'/o- Eye 4'/„ % in inter- 

 orbital space. Mouth obliquely ascending, lower jaw, which is 

 the longer, with a symphysial protuberance, corresponding to 

 a small cavity in the upper jaw. Barbels i'/4 the length of 

 the head, and reaching somewhat farther than the base of the 

 pectorals. Origin of dorsal above 5th ray of anal, separated 

 by 24 scales from occiput, slightly in advance of the second third 

 of the length. Anal emarginate, the anterior rays the longest, 

 beginning in the third fifth of the length. Ventrals not reaching 

 anal, half their length distant from it. Pectorals falcate, pointed, 

 equal to '/^ of the length of the body, surpassing base of 

 ventrals. Caudal deeply emarginate, the lobes pointed, some- 

 what longer than head. Yellowish brown, back dark, an irre- 

 gularly broad longitudinal dark band from opercle to caudal, 

 ending in a triangular patch and containing a blotch above

 obliquely directed upwards. No hook at mandibular symphysis,

 barbels. Eye with a free orbital margin. Dorsal short, without 

 strong spines, its origin opposite to that of anal, which is 

 many-rayed and much longer than dorsal. Ventrals inserted 

 slightly above the abdominal edge, situated distinctly before 

 middle of length, their outer ray elongated. Pectorals longer 

 than head. Caudal forked. Scales rather large, of about equal
