caudal. Head about 3.5, 4.1 4.4 in length with caudal. Eye 

 3 3 ] / 2 , shorter than flat interorbital space and shorter than 

 snout, nearly equal to but always less than 1 J 9 shorter than 

 postorbital part of head. Skin of head gelatinous, with a 

 multitude of parallel, more or less wavy sensory lines. Snout 

 blunt, prominent. Lips swollen, the lower one mesially with a 

 posterior curve, its frontpart with longitudinal folds. The 

 lower jaw received within the upper. Barbels 4, small, much 

 shorter than half eye, the posterior pair near the corner of 

 the mouth, longer than the anterior ones ; the base of both is 

 hidden in a fold of the skin, running before upper lip to 

 behind corner of mouth. Mouth subinferior, strongly arched. 

 Origin of dorsal about in the middle of a line connecting end 

 of snout with end of shortest caudal rays, opposite to I I th lateral 

 scale, separated by 13 14 scales from occiput, situated behind 

 origin of ventrals. Dorsal concave, total length of its fourth 

 osseous very strong spine, the hindborder of which is roughly 

 denticulated, together with its flexible portion about equal to 

 head, and about i ! / 2 in height of body. Anal concave, its 

 third strong spine about equal to length of head without snout. 

 Origin of ventrals separated by 4 scales from the Qth scale of 

 the lateral line. Ventrals about 2 / 3 of length of head, surpassing 

 anus. Pectorals reaching ventrals, about 3 / 4 length of head. 

 Caudal deeply incised, its lobes broadly rounded, shorter than 

 head. Scales rather thin, finely longitudinally striated with 

 parallel lines. Least height of caudal peduncle twice in length 

 of head and less than length of caudal peduncle, surrounded 

 by 20 scales. Yellowish, back dark, 9 longitudinal dark bands, 

 formed by corresponding series of black spots on the scales, 

 the upper and lower of which are the faintest. A large black 

 patch in the lateral line somewhat before origin of caudal.
