on the Mammalia in the Zoological Museum. Ill 



The dimensions of our animal are fully one-third less than those of our 

 specimen o^nasicus. On these latter points we do not wish to lay much 

 stress : individuals of the same species in this family vary considerably in 

 these characters. The claims of our animal to a separate specifick title 

 rest chiefly on the character of the nose and facial angle. Its teeth 

 show no signs of being otherwise than adult. Its length from the 

 vertex of the head to its heel as it stands upright is 36 inches; from the 

 same point to the commencement of the tail, 21 ; the fore-foot from the 

 heel to the end of the middle finger is 7 inches in length; the hind- 

 foot 6. 



Fam. LEMURiDiE. 



Gen. Cheirogaleus. Geoff". 



The first notice, which was given of this new form among the Lemurs^ 

 is to be found in the MSS. of M. Commerson. Three species belonging 

 to Madagascai- are represented in the designs of that voyager, but not 

 with sufficient accuracy in the details to enable us to recognise any deci- 

 sive specifick characters. Upon this authority M. Geoffroy de St. Hilaire 

 subsequently established the genus in Xho. .4nnales du Museum:* but 

 no specimens of the form pointed out by M. Commerson having come 

 under the observation of naturalists, the genus has been considered as 

 doubtful. MM. Cuvier and Desmarest merely refer to it in their notes, 

 and M. Lesson, although he enumerates it in the list of the genera given 

 in his " Manuel," describes it as not yet authenticated. 



An animal lately presented to the Zoological Society by Mr. Bell, one 

 of the most active and liberal members of the Society, and one of the co- 

 operators in this Journal, accords very accurately with M. Commerson's de- 

 scription of this genus, as detailed by M. Geoffroy. It gives us great pleasure 

 to have it in our power to announce this fact to zoologists; which, although 

 it does not enable us to refer the animal to any of M. Commerson's 

 species, serves to prove the genus itself authentick. We shall not, how- 

 ever, enter further into the subject at present than the description of the 

 species. The skull is perfect ; but the teeth cannot be examinedf with-
