of head equals its height or its length excluding the snout. Lips moderately thick and 
rugose ; lower labial 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 1S 
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 tin 
commencement of the dorsal fin : it is shorter than the pectoral, but extends to the base o 
the anal. Anal twice as high as long, and reaches above half-way to the base of the caucia 
which is emarginate. Free portion of the tail twice as long as high at its base. Scales 
absent. Colours : of a light fawn, with sixteen or eighteen interrupted darker and sinuous 
hands passing from the hack down the sides ; a silvery lateral hand. Dorsal and caucia 
finely spotted in lines : a darkish hand on pectoral, ventral and anal. 
Sab. 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 Britis 
Museum specimen, and the broken state of its caudal fin, must he accepted as the reason 
why my proportion of the free portion of the tail does not agree with Dr. Gunther’s (neai „ 
i) ; whilst I find the caudal fin “emarginate,” and not “rounded.”
