The height of the body is contained four times in the total length 

 (without caudal), the length of the head thrice and two-thirds ; head 

 as high as broad, its greatest width being two-thirds of its length ; 

 the occipital process is elongate, extending on to the basal bone of 

 the dorsal spine ; the upper jaw projects beyond the cleft of the mouth, 

 which is nearly straight. Barbels very slender and short ; those of 

 the maxillaries extend to, or somewhat beyond, the eye. The dorsal 

 spine is of moderate length, serrated behind, its length being con- 

 tained once and a half or once and three-fourths in that of the head. 

 The length of the adipose fin nearly equals its distance from the 

 dorsal, and is less than twice the length of the dorsal. Pectoral spine 

 strong, as long as that of the dorsal fin, serrated interiorly. Caudal 

 deeply forked. Brownish, with irregular dark cross-bands ; fins with 

 two broad brown bands.

The height of the body is contained five times and a half or six 

 times in the total length (without caudal), the length of the head 

 thrice and two-fifths or thrice and three-quarters ; head rather 

 broader than high, its depth being one-half of its length. Occipital 

 process very short, terminating at a great distance from the base of 

 the dorsal. The upper jaw projects beyond the cleft of the mouth, 

 which is nearly straight. Barbels slender and short ; those of the 

 maxillaries extend to the eye only, or to the opercles. The dorsal 

 spine is of moderate strength, serrated behind, its length being one- 

 half, or rather more than one-half, of that of the head. The adipose 

 fin is more than twice as long as the dorsal, and commences at a 

 considerable distance behind it. Pectoral spine strong, serrated in- 

 teriorly, about as long as that of the dorsal fin. Caudal deeply forked. 

 Brownish with irregular dark cross-bands ; a brown lateral band 

 running from the head to the caudal ; fins with one or two brown 

 bands.
