intermediate condition, then those who would make C. furcifer the 

 type of a new genus on such grounds may find themselves logically 

 compelled to make a separate genus of each species. 



This new form has recently been described and figured by MM. 

 H. Schlegel and Francois P. L. Pollen (in the first number of their 

 Recherches sur la Faune de Madagascar, 1867, p. 12, pi. 6). The 

 authors remark that it is " plus voisine du Microcebus typicus de 

 Smith que des autres especes ; " but add that Dr. Peters found it, 

 although similar in size, to differ from the latter species by its tail 

 washed with black, by the absence of the black circles about the 

 eyes, and by the length of its ears, which are one-third longer than 

 those of the so-called M. typicus. The skull, unfortunately, is not 

 yet figured ; and in the absence of any description of it, or of the 

 dentition, it is impossible to say definitively whether it should be 

 placed in the genus Cheirogaleus or in Microcebus. Its resemblance 

 to the British-Museum specimen, however, would suggest its loca 

 tion in the former genus ; and, as before said, it may be that its 

 characters may justify (if they offer a certain intermediate structure) 

 the fusion of the two genera into one by the abolition of the term 

 Microcebus altogether. 



The next form to be noticed is one of great interest, namely Lepi- 

 lemur, a genus still absent (as far as 1 know) from all the collections 

 in this country. In Paris there is a skin (the type of the genus and 

 species) of L. mustelinus, also the skull extracted from it, and a 

 skull of the new species {L. ruficaudatus) recently characterized* 

 by M. Alfred Grandidier. 



Lepilemnr mustelinus has recently been described and figured by 

 Messrs. Schlegel and Pollen (in their work above referred to, at p. 10, 

 pi. 4). L. ruficaudatus is as yet unfigured. 



In the skulls of both these species there is no trace of any upper 

 incisor ; and the specimens show the correctness of M. Gervais's 



Lcpilcmur mustelinus.
