points being in the proportion of 5 : 6. By " root of the tail" is 

 meant the point where the lateral line ends against the caudal fin. 



The anal fin contains three spines and six rays, and nearly 

 touches the caudal when laid flat. 



The pectoral, pelvic, and anal fins very nearly of the same 

 length, which is slightly less than the postocular part of the head. 



There are no — 120 scales in the lateral line. Behind the oper- 

 culum the scales are arranged in eight to ten rows, placed one above 

 the other; in each row there are two to four scales, they are irregu- 

 larly imbricated. The "tiled" row contains thirty to thirty-five 

 scales, on either side of the vent the diameter of these scales is | 

 that of the eye in front, and behind the vent their diameter becomes 

 considerably less. 



There are no barbels. 



Pharyngeal teeth 4.3 | 3.4 ; the teeth of the outer row are longer 

 than those of the inner and are curved. 



Colour. — Silvery with dark uniformly distributed small blotches 

 apparently under light control. Top of head dirty olive extend- 

 ing on to the cheek, dorsal and caudal fins dirty olive. Pelvic, ven- 

 tral and anal fins orange-red near the free margin. 



An active predatory fish ; a small fish of another species was 

 taken from the stomach of one of the specimens. 



Schizothorax o'connori, n, sp. (PI. xxv, fig. 3.) 



Length of the head to the length of the body (without caudal) 

 bears the proportion i : 5. 



The greatest depth of the body is a little more than the length 

 of the head. The diameter of the eye is -^ of the length of the 

 head. The eye is nearer to the snout than to the posterior border 

 of the operculum, being separated by two diameters from the former 

 and three diameters from the latter. 



The diameter of the eye is to the length of the interocular dis- 

 tance as 2 : 5. 



The shape of the head is that of a bluntly pointed cone : be- 

 tween the eyes the head is nearly flat, but in the middle line a 

 raised crest of the frontal bone projects slightly, (This may only 

 be visible in the spirit specimen.) 



The mouth is transverse and is only slightly curved. The 

 snout projects well beyond the level of the lower jaw. The posterior 

 barbel is in length about f of the diameter of the eye, the anterior 

 barbel being somewhat less than this. 



The dorsal fin is situated behind the level of the ventrals, its 

 first spine is somewhat nearer to the root of the tail than to the 

 snout, the proportion of the distances which separate these points 

 being as 6 : 7. 



There are three spines and eight soft rays in the dorsal fin, the 

 third spine being equal to the length of the head without the snout. 

 In the character of this spine the two specimens differ considerably ; 

 in the larger specimen the serrations are distinct but small, and the
