of head equals its height or its length excluding the snout. Lips moderately thick and 
rugose; lower lahial fold interrupted in the middle. Barbels 6; the maxillary ones scarcely 
reach to below the front edge of the eye, the longest rostral ones to below the front nostril. 
Fins: dorsal commences midway between the front edge of the eye and the base of 
the caudal fin: it is as high as the body below it and half higher than its base is 
long; its upper anterior corner rounded. Pectoral as long as the head behind the 
angle of the mouth, and reaching nearly to the ventral, which latter fin arises below the 
commencement of the dorsal fin: it is shorter than the pectoral, but extends to the base of 
the anal. Anal twice as high as long, and reaches above half-way to the base of the caudal 
which is emarginate. Eree portion of the tail twice as long as high at its base. Seales 
absent. Colours: of a light fawn, with sixteen or eighteen interrupted darker and sinuous 
bands passing from the back down the sides; a silvery lateral band. Dorsal and caudal 
finely spotted in lines : a darkish band on pectoral, ventral and anal. 
Lab. Gnari Khorsum, Tibet. The specimen described is the largest of two obtained by 
Messrs, von Schlagintweit, and deposited in the Indian Museum. The size of the British 
Museum specimen, and the broken state of its caudal fin, must be accepted as the reason 
why my proportion of the free portion of the tail does not agree with Dr. Gunther’s (nearly 
J); whilst I find the caudal fin “emarginate,” and not “rounded.”

Length of head 5 |, of caudal 64 , height of body 6y; in the total length. Lyes: 
diameter 11 in length of head, 1 diameters from end of snout, and 2^ apart. Snout 
overhanging the mouth. The greatest width of the head equals its height or its length 
excluding the snout. Lips thickened; lower labial fold interrupted in the middle and rather 
lobed on either side. Barbels six; the maxillary ones nearly twice as long as the eye; the 
external rostral ones reach the hind nostril; the other pair are shorter. Fins: dorsal com¬ 
mences midway between the eye and vertical border of the preopercle; its upper edge is 
nearly straight; it is not quite so high as the body below it, and one-fourth less than the 
extent of its base. Pectoral as long as the head behind the angle of the mouth; it reaches 
rather above half-way to the base of the ventral, which latter fin arises somewhat in advance 
of the commencement of the dorsal; it is of about the same length as the pectoral, and ex¬ 
tends half-way to the anal. Anal twice as high as wide at its base: it reaches, when laid flat, 
a little more than half-way to the base of the caudal, which is slightly emarginate. Eree 
portion of the tail half as high at its base as it is long. Scales absent. Colours brownish 
along the back, becoming yellowish beneath : dorsal and caudal with dull spots. 
Lab. Basgo, on the head waters of the Indus.
