Length of head 6, of caudal 6 ; height of hody 8 in the total length. Eyes : diameter 8 

 in the length of head, 3 diameters from the end of snout, and 2 apart. Snout rounded, 

 slightly projecting over the mouth. Lips rugose ; and in some specimens from Yarkand the 

 edges are fimbriated : lower lip with a lohe on either side, but the lower labial fold interrupted 

 in the middle. The greatest width of the head equals its height, or its length excluding 

 the snout. In some specimens the preorbital has a free lower edge. Barbels six; the 

 maxillary ones reach beyond the hind edge of the eye ; the rostral ones are shorter. Fins : 

 the dorsal commences midway between the eye and the base of the caudal, it is one-third 

 higher than its base is long, and equals the greatest depth of the body ; its last ray is divided 

 to its base ; its upper edge is oblique, with a rounded anterior angle. Pectoral nearly as long 

 as the head, and reaching rather above half-way to the ventral ; the latter fin arises on a 

 vertical line below the anterior dorsal rays, is almost as long as the pectoral, and reaches 

 above half-way to the anal. Anal with a very narrow base : caudal slightly emarginate. 

 Free portion of the tail from twice to two-and-a-half times as long as high at its base. 

 Scales : absent. Air-vessel : in two portions, enclosed in bone. Colours : greyish along the 

 back, becoming lighter beneath, marbled all over with dark green or black spots or bands. 

 Dorsal, caudal, and sometimes outer pectoral rays barred. 



In specimens from Sarikol the snout is rather more pointed than described above. 



Hab. Leh (11,518 feet) ; Snima ; Lukong stream (14,130 feet) ; and Chagra (15,000 

 feet), all being waters directly or indirectly going to the Indus. Also Yarkand (3,923 

 feet) and Sarikol, where the waters go to the easterly or Yarkand River ; and Aktash 

 (12,600 feet), which is on the Aksu or Oxus. 



I have a specimen in my collection given me by Dr. Stoliczka : he procured it, along 

 with those sent to Steindachner, from the Tso-Morari in Rupshu (Tibet), on his first visit 

 to that country.

 B. iii, D. f , P. 17, V. 8, A. |- , C. 15. 



Length of head 4^, of caudal 6, height of body 6f in the total length. Eyes : diameter 

 6 to 7 in the length of the head, 2 diameters from the end of snout, and 2 to 3 apart. 

 Snout : rather elevated in the adult. Upper surface of the head nearly flat ; its greatest width 

 equals its height or its length excluding the snout. Mouth inferior, horseshoe-shaped ; lips 

 smooth, lower labial fold interrupted in the middle and destitute of lobes. Barbels six ; the 

 maxillary ones reach (in adults) the angle of the preopercle. Fins : the dorsal commences
