about an equal distance from the forehead and the vertex. Except in 

 these respects tlie two animals are perfectly similar in appearance, in 

 proportions, and in manners. The differences between them have yet 

 been ascertained on only a single individual of the Paias d, bandeau 

 blanc, which appears to be extremely rare, and M. F. Cuvier therefore 

 expresses some uncertamty as to their value ; nor does he venture to de- 

 cide, although he looks upon these as equalling in importance the dis- 

 tinctions between the Callitriche and other nearly allied Cercopitheci, 

 whether they should be regarded as characteristic of a species, or merely 

 as indicative of a strongly marked variety. 



The Sciurus ferrugineus is a native of the Peninsula of Hindoostan. 

 It somewhat exceeds in size the common Squirrel of Europe, and is sub- 

 ject to some variation in its colours. It is usually of a brilliant golden 

 chesnut, which is rather lighter on the under surface than above ; the 

 toes are covered with black hairs, and the whiskers are also black. The 

 ears are not tipped with tufts of hair. The long hairs are most numerous 

 on the back and sides, and clothe the tail completely ; and the woolly 

 hairs are in very small quantity in every part of the body. In the indi- 

 vidual figured, from a drawing by M. Duvaucel, the long tuft of hairs at 

 the tip of the tail is white ; a variety in colour which appears to be 

 merely accidental.

On tbe gratitude of zoologists the government of France possesses no 

 slight claims for the liberality with which its influence is exerted in pro- 

 moting the advancement of the science which hey cultivate. Not to 

 mention the Museum and the Menagerie which it has created in Paris, 

 and which have been rendered by its continued support daring a series 

 of years almost the centre of zoological knowledge, especial thanks are 

 due for the attention which has been directed under its authority in all 

 the recent voyages of discovery to the acquisition of subjects from the 

 animal kingdom, and of information respecting them. Quahfied persons
