[No. 35, 



* Leuciscus meltttina. (Val.) 

 Head equal to the depth, and one-fifth of total length of body ; 

 eye one-fourth of head ; lower jaw with a small tubercle on its sym- 

 physis ; 50 and more scales along its body ; lateral line concave ; cheeks 

 burnished silver, which extends along the sides of the body in a line 

 distinct from the silver of the abdomen — D. 11, A. 8, &.c. — 3j inches 

 long. From Bombay. 



* Leticiscus Mahecoloe. (Val.) 

 Head shorter than the height of the body \vhich is 4 times in to- 

 tal length ; muzzle somewdiat pointed, eye rather large, profile of 

 back, and that of abdomen, similar and regular; scales large, 22 

 along the sides ; lateral line slightly concave, on the 5th range, and 

 two scales lower are observable, a series of small depressions, which 

 are probably pores ; greenish above, silvery beneath ; dorsal reddish, 

 pectoral and caudal greenish, the latter with a little black at the 

 point of the lobes ; ventral and anal colourless — -D. 11, A. 7, &c. — 3 

 inches long. From Mahi on the Malabar coast; appears allied in form 

 to my L. flatus. 



Leuciscus har'batus* New Species. 

 2 cirri on each side of its mouth, the posterior long, reaching to 

 the ventral fin; head four times and two-thirds in its total length ; 

 profile nearly straight to the dorsal fin, which is placed well behind, 

 slightly concave thence to tail ; abdomen arching regularly to the anal ; 

 height is about 4 times in its length, lateral line near the abdomen 

 and parallel with it ; 32 scales along the body in 7 rows ; dorsal fin 

 small, not so long as anal ; caudal fin large ; green above, silvery

This fish very closely resembles the one described by Valencien- 

 nes as Nuria thermoicos, but appears to differ in some particulars of 

 form, color, and remarkably so in its habit, the latter being found 

 in hot springs of the temperature of above IOC Fahr. Buchanan 

 has also an allied species, his C. dourna. Valenciennes places his 

 Nuria between his genera Dangila and Kdhita ; a most unfortunate 

 position, and one which shows how little idea of natural affinities he 

 possesses. Were it not for its cirri it would barely differ from some 

 of the Leucises just described. McLelland places another yery
