separated from the pectorals by any great distance ; their origin is 

 distinctly nearer to the root of the caudal fin than to the tip of 

 the snout. The ventrals almost reach the base of the anal fin 

 which contains 9 rays, the anteriormost of which is not branched. 

 The caudal fin is long and its free posterior border is almost semi- 

 circular ; the two extremities are sliarp and pointed. 



The air-bladder has receded inwards towards the vertebral 

 column and consists of two chambers, one on either side of the 

 basioccipital process of the skull. The occipital, cubito-humeral 

 and the scapular processes are finely tuberculated and there is a 

 bony nodule covered by skin below the base of the dorsal spine. 



Colour. — The sides and dorsal surface of the head are black ; 

 the ventral surface is dull white. The general colouration of the 

 body is pale 3'ellow, but the sides are marked with two broad 

 black bands formed by an aggregation of black dots. The ante- 

 rior band is below the bases of the anterior dorsal fins and the pos- 

 terior band is situated below the bases of the adipose dorsal and 

 the anal fins. The fins are indistinctly marked with black bands. 



Type-specivicn. — F 10085/1, Zool. Surv. Ind. {Ind Mus.). 



Localily. — There are three specimens in Mr. Shaw's collection, 

 two from the Mahanadi River and one from the vSivoke River. 

 Both these rivers flow at a very low altitude at the base of the 

 Darjiling Himalayas.

This species differs from the preceding in several respects 

 and was obtained by Mr. Ribeiro in an adjacent locality. The 

 following table shows some of the salient points in which the two 

 species differ : — 



L. shawi, sp. nov. 



The nostrils are equidistant from 

 the tip of the snout and the anterior 

 margin of the eye. 



. The origin of the ventral fin is 

 distinctly nearer to the base of the 

 caudal than to the tip of tlie snout. 



L. ribeiroi, sp. nov. 



The nostrils are nearer to the tip of the 

 snout than to the anterior margin of 

 the eye. 



The origin of the ventral fin is almost 

 equidistant from the dp of the snout 

 and the base of the caudal fin.
