so high at its commencement as it is long. Colours-, silvery, with 

 black spots on the upper half of the body. 



This species has a more elevated dorsal profile and shorter barbels 

 than S. intermedins. 



Hab. Cashmere Lake. 



9. Ptychobarbus conirostris. 



Ptychoburbus conirostris, Steiudachner, Verb. z.-b. Ges. Wien, 

 I860, p. 7SH, t. xvii. f. 4 ; Giinther, Cat. vii. p. 169. 



B. iv., D. I P. 22, V. 10, A. 7-8, C. 19, L. 1. 95, L. tr. 24/. 



Length of head l| to 5, of caudal 7j, height of body 6| 

 to ()f in the total length. Eyes : diameter from A\ to 5j in 

 the length of the head, 2 diameters from the end of snout, and 

 \\ apart. The greatest width of the head equals its postorbital 

 length, but is slightly less than its height. Mouth horseshoe- 

 shaped, with the upper jaw a little the longer, and rather overhung 

 by the snout ; the maxilla reaches to below the front edge of the 

 eye. Lower labial fold very broad, uninterrupted, and with a cleft 

 in the median line posteriorly. Barbels: a pair at the angle of the 

 month, which reach the posterior edge of the preopercle ; in a small 

 specimen, 3*1 inches long, they only equal § a diameter of the eye 

 in extent. Teeth : pharyngeal ones in two rows. Fins : the dorsal 

 commences much nearer the snout than the base of the caudal, its 

 entire base being equidistant from these two points ; it has no 

 osseous ray, and is as high as the body below it. Pectoral as long 

 as the head behind the nostrils, and does not reach quite so far as 

 the ventral, which latter fin arises under the last few dorsal rays 

 and reaches two thirds of the distance to the base of the anal. The 

 anal, when laid flat, reaches the base of the caudal, its base is 2^ 

 in its height. Scales : the tiled row small, not one third of the 

 diameter of the eye. Colours: silvery, darkest along the back and 

 upper half of body, where most of the scales have black margins, 

 thus causing small reticulations in the colour. Upper surface of the 

 head spotted with black ; some spots on the dorsal fin, and some- 

 times a few light ones on the caudal. 



Hab. Head-waters of Indus, Hanli in Tibet, and Chiliscorus. 



10. Ptychobarbus laticeps, sp. nov. 



B. iv., D. J, P. 18, V. 9, A. ?, C. 20, L. 1. 145. 



Length of head 4 j, of caudal 9h, height of body 7 in the total 

 length. Eyes : diameter 12 in the length of head, 2^ diameters from 

 the end of snout, and also apart. Mouth anterior, with the lower 

 jaw somewhat the longer ; the depth of the cleft of the mouth 

 equals half the width of the gape. Upper surface of the head 

 broad, its width being nearly twice its height. No lower labial fold 

 under the mandible. Barbels : a maxillary pair as long as the eye. 

 Fins : dorsal arises slightly nearer the base of the caudal than the 

 end of the snout ; its last undivided ray weak, articulated at its ex-
