Length of head 5, of caudal 4|-, height of body 3 in the total length. Eyes — diameter 3 to 3i in 

 length of the head, 3/4 to 1 diameter from end of snout. Upper profile slightly concaye over the nape, rising 

 considerably to the base of the dorsal fin, and much more convex than that of the abdomen. Body compressed. 

 Third suborbital bone very narrow. Mouth narrow, horse-shoe shaped, the upper jaw very slightly the longer 

 when the mouth is closed. Fins — dorsal arises over or slightly in advance of the ventral, and midway between the 

 end of the snout and the base of the caudal, its smooth osseous ray is not strong and as long as the head 

 without the snout ; upper margin of the dorsal fin slightly concave, its height is only slightly above one-half of 

 that of the body. The pectoral extends to the ventral, and the latter to the anal. Lower caudal lobe sUghtly 

 the longer. Lateral-line — complete, 3^ rows of scales between it and the base of the ventral fin : 9 rows 

 before the dorsal fin. Colows — dull silvery, darkest along the back, and each scale having a dark base formed 

 by fine black, dots. Dorsal, ventral, and anal fins generally stained with black spots at their extremities, but in 

 some specimens only the anal. A dark mark at the base of 3rd to 7th divided dorsal rays, sometimes a dark 

 mark at base of the tail. 



Habitat. — Assam, Bengal, N. W. Provinces, Punjab and Sind. The spedmen figured (life-size) was 

 from Roorkee.

Length of head 4j, of caudal 4j, height of body 3f in the total length. Eyes — diameter 3j in length 

 of head, 1 diameter from end of snout. Dorsal profile more convex than the abdominal. Body very compressed- 

 Jaws of about equal length : interorbital space convex. Barbels — absent. Fins — dorsal commences nearer the 

 end of snout than the base of caudal fin, it is only two-thirds as high as the body, its osseous ray moderately 

 strong, rather longer than the head without . the snout. Lateral-line — incomplete, ceasing after eight scales. 

 (7oZoMrs— silvery, a round black finger mark on either side of the free portion of the tail anterior to the base 

 of the caudal fin, and a second at the base of the first few dorsal rays. 



Habitat. — From a hot spring in Ceylon ; attaining at least 3 inches in length. This description is from 

 the type specimen which is at Paris.

Length of head 4 to 4i, of caudal 4, height of body 3 in the total length. %es— diameter 2f to 3 in 

 length of head, 3/4 to 1 diameter from end of snout, IJ diameters apart. Interorbital space flat. Body compressed, 

 dorsal profile more- convex than that of the abdomen, there being a considerable rise from the snout to the 

 base of the dorsal fin. Upper jaw slightly the longer. Barbels— absent. Fins— dorsal arises slightly in advance 

 of the ventrals, and midway between the end of snout and base of the caudal, its last undivided" ray is osseous, 

 entire, moderately or very strong, and nearly as long as the head : the fin is almost as high as the body below it. 

 Lateral-line-inoom-plete, ceasing after 3 or 4 scales : 3 rows between the lateral-line and base of the ventral 

 fin : 9 rows m front of the dorsal fin. CoZows— silvery, greenish along the back, and each scale having a 

 number of fine black spots most numerous at the anterior margin. A large black blotch in the middle of the 

 side over the posterior extremity of the anal, which is sometimes extended in the median line as far as the tail. 

 A very mdistmct black blotch (most apparent in the immature) exists under the posterior extremity of the 

 dorsal passing downwards to the middle of the fish. Fins yellovnsh, their margins stained with black, the 

 dorsal having a median band. In some specimens there is a dark mark at the bases of the scales. 



HabUat.—Orissa, Bengal to the Punjab. It attains 3 or 4 inches in length. The specimen figured (life- 

 size) was from Orissa.
