(Plate i, fig. 3.) 



Br. iv; D. Ill 6-8; P. 15; V. 9; A. II 5; C. 17; L.l. 39-40; 



L.tr. 61/41. 



Length of head 3^ to 3!, height of body 3f to 3|, length 

 of middle (shortest) raj^s of caudal fin 9 and outer (longest) rays 

 41 times in the total length. Length of caudal peduncle little 

 less than 4 times in the total length. Height of head i^ times 

 and width of head i-| times in the length of head. 



Shape. — From snout to some distance behind the nape the 

 dorsal profile is almost a straight line from which point it is convex 

 up to second dorsal spine which occupies the highest point, from 

 this point it slopes down in a gentle concave curve to be continuous 

 with the upper outermost ray of the caudal fin. The ventral 

 profile is almost a straight line with a slight convexity at the root 

 of the ventral fin, whence it curves up suddenly and continues 

 again as a straight line to the base of the caudal peduncle. 



Snout. — Depressed, with a pointed ridge in front. It is en- 

 tirely free from pores and tubercles. 



Barbels. — 4; 2 rostral, slightly shorter than the diameter of 

 eye and contained if times in the length of the maxillary and 

 4I in the length of head, and 2 maxillary, contained 3 times in the 

 length of head. The rostrals reach the anterior one- third of the 

 eye, whereas the maxillaries reach the hind edge of the orbit. 



Eyes. — Comparative!}^ large, 3^ diameters in the length of 

 head, i diameter from end of snout and i apart. Interorbital 

 space flat. 



Mouth. — Anterior, terminal, protractile and curved. Upper 

 jaw slightly projecting, the angle of the lower jaw is pointed, with 

 a tubercle which fits into the angle of the upper jaw. The opening 

 of the mouth ends considerably anterior to the vertical from the 

 anterior orbit, the distance being greater than half the diameter 

 of the eye. 



Teeth. — Pharyngeal 4,3,2; 2, 3, 4, The outer are larger. 



Fins. — The dorsal arises two scales behind the vertical from 

 the anterior root of the ventral, has about 21 scales in front and is 

 nearer to the root of the caudal than the end of the snout. The 

 third spinous ray is serrated posteriorly with 28 serrations, the 

 terminal one being slightly hooked; this spine is shorter than the 

 length of head ; the rest of the rays are shorter the further the}^ 

 are from the spine ; the free edge of the fin is thus concave out- 

 ward. The pectoral reaches above the ventral by one or two 

 scales and the lower free margin is slightly concave. There are 

 twelve rows of scales between the anterior roots of ventral and anal ; 

 the length of ventral is less than the intervening space. There 

 are 3^ scales between the root of the ventral and the lateral line
