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. Pree portion of the tail 
rather longer than hi ah. Colours bluish on the hack, lightest below, dorsal and caudal 
spotted. 
Ilab. Yarkand, whence the stuffed specimen described was brought. It is 31 inches in 
length. This species scarcely accords with the definition of Btychoibarbus , the last undivided 
dorsal ray being osseous and finely serrated. The specimen, however, is large, whilst JP. laticeps 
f orms the intermediate form between it and P. conirostris.

Length of head 5 to 5f, of caudal 5J to 5§, height of body 7 to 8 in the total length. 
Eyes : diameter 4 to 5 in the length of head, 1 to 1^ diameters from end of snout, and ly to 
2 apart. The greatest width of the head equals its length behind the middle of the eyes , 
und its height equals its length excluding the snout. Mouth inferior, overhung by the 
s uout ; the maxilla reaches to below the front edge of the eye. A sharp, anterior, homy 
edge to the mandible. Barbels absent. Fins : 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, 
a nd 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 gent y, anc 
then reascending, attains the middle of the body opposite the posterior extremity of the orsa 
hn. Colours olive superiorly, becoming white on the sides and beneath ; the w io e covcrcc 
^ith irregular blackish spots. .
