strength, and very finely serrated posteriorly; its osseous portion equals a little above one- 
fourth of the length of the head. Pectoral half as long as the head, and reaches half-way to 
the ventral; the latter fin commences under the first divided dorsal ray, and does not extend 
quite half-way to the root of the anal. Anal twice as high as its base is long; it does not 
reach the caudal when laid flat; the latter fin forked. Scales oval, nearly as wide as high 
and slightly imbricate; the tiled row half the diameter of the eye. Tree portion of the tail 
rather longer than high. Colours bluish on the back, lightest below, dorsal and caudal 
spotted. 
Sab. Yarkand, whence the stuffed specimen described was brought. It is 81 inches in 
length. This species scarcely accords with the definition of Btychobarbus, the last undivided 
dorsal ray being osseous and finely serrated. The specimen, however, is large, whilst P. laticeps 
forms the intermediate form between it and P. conirostris.

Length of head 5 to 5f, of caudal 5^ to 5f, height of body 7 to 8 in the total length. 
Byes: diameter 4 to 5 in the length of head, 1 to L|- diameters from end of snout, and 1| to 
2 apart. The greatest width of the head equals its length behind the middle of the eyes ; 
and its height equals its length excluding the snout. Mouth inferior, overhung by the 
snout; the maxilla reaches to below the front edge of the eye. A sharp, anterior, horny 
edge to the mandible. Barbels absent. Bins: the dorsal commences about midway between 
the end of the snout and the root of the caudal; its upper edge is nearly straight, oblique; 
the fin is as high as the body below it, and one-third higher than its base is long; its last 
undivided ray osseous and finely serrated posteriorly. Pectoral not quite so long as the head, 
and reaching rather above half-way to the ventral, which latter, arising below the middle of 
the dorsal, is slightly the shorter, and does not reach the anal. Anal, when laid flat, reaches 
the base of the caudal; it is rather above twice as high as its base is long. Caudal deeply 
forked. Pree portion of the tail as high as long. Lateral line at first descends gently, and 
then reascending, attains the middle of the body opposite the posterior extremity of the dorsal 
fin . Colours olive superiorly, becoming white on the sides and beneath; the whole covered 
with irregular blackish spots. 
The ova are comparatively large. The serrated dorsal spine is strongest in specimens 
from Leh. 
These fishes appear to be much attacked by parasites, which occasion yellowish elevated 
tubercles, not only on the head and body, but also on the dorsal fin. 
One specimen, from Balakchi, had a shot (No. 2) imbedded in the isthmus, where the 
parts around it had healed. 
Sab. Leh, Tankse, and fry or small fish from Lukong and Chagra (15,090 feet), 
all from waters directly or indirectly going to the Indus. Some fry from Sarikol, the 
waters of which go to the Yarkand Liver l , Aktash, Upper Kara-kul and Panjah, tributaries 
of the Oxus or Amu Liver. This fish has also been taken at Gnari Khorsumby Schlagintweit. 
1 I am very dubious of these specimens, and hardly think they can have been obtained from waters that flow into the Yarkand 
Kiver, as the adults have not been obtained thence. The adult, however, has been taken in the Oxus ; and I find by the diary that 
on the day the specimens in question were captured the camp was at Sarikol, a few miles from a valley where a stream enters the 
Aksu River, a tributary of the Oxus.
