as long as deep. Greyish above, silvery below ; upper part 

 of body with ivregnlnr dark spots. 



Ten specimens, 110-2;")0 mm. in total length. 



2. Schizothorax dipogon. 



Depth of body about 5^ in the lengtli, length of head 4i. 

 Upper profile of head nearly horizontal to just in front of the 

 nostrils, where it bends abruptly downwards and becomes 

 nearly vertical. Breadth of head If in its length. Snout 

 obtuse, much shorter than postorbital part of head. Diameter 

 of eye 6 in the length of head, iiiterorbital width 3^. ^Mouth 

 subtermiiial ; lower jaw api)arently Avithout horny covering ; 

 lips strongly developed, continuous, the upper with median 

 prolongation, the lower notched mediauly. No anterior 

 barbel ; posterior barbel 1^ the diameter of eye. Scales 

 regularly arranged anteriorly above the lateral line, becoming 

 smaller and irregular on the lower part of the side in the 

 abdominal region ; lower part of thorax and abdomen naked ; 

 about 90 scales in a longitudiiuil series. Dorsal III 8, the 

 third simple ray slender, articulated, not serrated ; origin of 

 dorsal far in advance of the bases of the ventrals, nearer to 

 tip of snout than to base of caudal. Anal III 6. Pectoral 

 extending a little more tlian ^ tlie distance from its base to 

 the base of ventral ; ventral extending | of the distance from 

 its base to the origin of anal. Caudal forked. Caudal 

 peduncle 2| as long as deep. Brownish above, lighter 

 below; daik spots on the upper surface of the head and one 

 on each scale of the upper part of the body. 



A single specimen, 265 mm. in total length. 



In the peculiar shape of the head, the structure of the lips, 

 and in having the third simj)le ray of the dorsal slender and 

 articulated this species resembles S. Regelii, Herz., but differs 

 notably in the absence of the anterior barbels and in having 

 the thorax and abdomen naked. 



3. Schizotlwrax Waltoni. 



Depth of body A^ in the length, length of head 4. Upper 

 profile of head descending slightly to above the nostrils and 

 thence more strongly to the tip of snout. Breadth of head 

 twice in its length. Snout pointed, a little shorter than post- 

 orbital part of head. Diameter of eye (S\ in the length of 

 head, interorbital width 03. Mouth subterminal; lower jaw 

 apparently without horny covering ; upper lip sligiitly 

 elevated medianly ; lower lij) with a small median lobe and 

 a pair of well-developed lateral lobes; 2 barbels on each side,
