Aplocheilus ruhrostigma. New Species. 

 A silver spot on the occiput ; body rather more compressed than 

 in the last, not much less in depth towards the tail than in front, dor- 

 sal with a black spot at its base ; it, the anal, and caudal fins, pale 

 sulphur yellow, red spotted ; body olive green above, yellowish on 

 the sides, and silvery beneath, with a series of longitudinal lines of 

 red dots along the sides — D. 7, A. 14 — ventral with the first very 

 elongated, small. Length barely 2 inches. Still more common and 

 abundant than the last in the same localities. 



Aplocheilus affinis. New Species. 



Very similar to the last ; differs in the dorsal and caudal being 

 nearly colourless unspotted, and the anal being unspotted orange, 

 and having 16 rays instead of 14, being at the same time of less ex- 

 tent, body also not spotted. About \\ inch in length. Found in 

 the same localities as the last. 



Aplocheilus Carnaticus. New Species. 



Abdomen more arched than in the three last species ; body much 

 narrowed behind ; dorsal small, anal long ; head small ; yellowish 

 green above, silvery on the sides and beneath ; caudal edged with 

 orange; dorsal and anal pale yellowish, with dark edges. Ventral 

 minute — D. 8, A. 22 — Hinch long. I procured specimens of this 

 minute fish in the river that passes by Waniambaddy in the Carna- 

 tic. It is very nearly allied in form, number of fin rays, &c. to 

 melastigma McL., but that is said not to exceed an inch in length, 

 and, being from Calcutta, is probably distinct. 



Gen. Colitis . 



Body elongated, cylindrical, head conical, with a thick fleshy cover- 

 ing; snout fleshy with small cirri ; mouth small; caudal entire, or slight- 

 ly lobed. 



Cohitis Carnaticus. New Species. 



Caudal with small pointed lobes ; head depressed, equal to the 

 depth, and 5^ times in total length ; 6 longish cirri ; dorsal rather in 

 front of the middle ; body olive green above, with dark blotches ; 

 dorsal and caudal spotted, the former yellowish, the latter reddish — 

 D. 9, A. 6. 



Found in sandy rivers in the Carnatic up to 3 inches in length.
