black, generally with about three or four yellowish rings. At a little 

 distance the animal appears to be of a deep brown colour. 



" The skins from which the above description was taken were 

 purchased at a sale of zoological subjects, the greater portion of 

 which were from Madras. As, however, there were some from the 

 Nilgherries, it is possible these specimens may have come from that 

 quarter.

" General colour very bright cinnamon yellow ; the hairs of the 

 upper parts of the body gray at the base ; cheeks whitish, a white 

 spot above, and extending behind the eye ; the feet and the whole 

 of the under parts of the animal white; the hairs of the same colour 

 at the base as at the apex ; tail brownish above, dirty- white be- 

 neath, the apical third furnished with long blackish hairs ; ears 

 blackish, sparingly clothed with white hairs ; hairs of the moustaches 

 black, some of those nearest the mouth white. 



" This species of Gerbillus, which I have great pleasure in naming 

 after M. F. Cuvier, who has published so excellent a monograph on 

 the group to which it belongs, I have reason to believe has long been 

 confounded with the animal described by Major-General Hardwicke, 

 in the eighth volume of the Linnean Transactions, under the name of 

 Dipus Indicus. The chief character which induces me to consider 

 it as a distinct species, consists in the comparatively great length of 

 the tarsus. In a specimen of Gerb. Indicus, which exceeds the present 

 animal in size, I find the tarsus to be only 1 inch and 6 lines in 

 length ; and in a specimen in the Paris Museum the foot was only a 

 quarter of a line longer, this animal being likewise larger than the 

 specimen which furnished the above description. In the same mu- 

 seum there is also a specimen of the present species, in which the 

 tarsus measured 1 inch 9 lin. ; the length of the animal being 7 inches 

 10 lin. In the specimen of Gerb. Indicus, and that of Gerb. Cuvieri, 

 belonging to the Zoological Society's Museum, there is a consider- 

 able diflFerence in the colouring, the latter being paler, and of a much
