CATALOGUE. 37 



A very perfect specimen of an Indian species of Lasiurus, from Dar- 

 jiling has been presented to the Company's Museum by Dr. J. T. 

 Pearson. As to its generic identity with the American species of this 

 genus, I have the opinion of Mr. J. E. Gray, of the British Museum, 

 who has examined the specimen. 



The entire length of Lasiurus Pearsonii is four inches and an half, of 

 which the tail constitutes one inch and an half; the anti-brachium mea- 

 sures two inches and a quarter, and the expanded membrane nearly 

 fourteen inches. Fur on the body above, very soft, silky, and rather 

 long. Colour on the head, neck, and shoulders, brownish-gray with a 

 ferruginous cast, variegated with whitish hairs ; the rest of the body 

 above, with the base of the membrane, the thighs, and the inter- 

 femoral membrane, have a deep bay or reddish-brown hue, and delicate 

 hairs of the same colour are scattered over the membrane, and project 

 from its border. The body underneath is thickly covered with a grey 

 fur, which is paler on the breast and throat. The interfemoral mem- 

 brane is marked with regularly parallel transverse lines. The ears are 

 more rounded than in the American species. The tragus is lanceolate, 

 and extends to the middle of the lobe. The flying membrane is brown.
