" 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 ej'e ; the feet and the whole 

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

 at the base as at the apej:: ; 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 exce]Ient a monograph on 

 the grou}) to which it belongs, I have reason to believe has long been 

 confounded \vith the animal describedby Major-General Hard\vicke, 

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

 Dipus Indicus. The chicf 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, ^vhich excceds the present 

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

 length ; and in a specimen in the Paris Museum the foot \vas only a 

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

 specimen ^A'hich furnished the above description. In the šame mu- 

 seum there is also a specimen of the present species, in \vhich 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 Societ)''s Museum, there is a consider- 

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

 brighter hue than the former ; but vvhether this difFerence is constant 

 I am not a\vare."
