higher and stouter facial region. At any rate, in all of them 

 the contours of the skull are cylindrical, and not pyriform as 

 in M. longirostris.

2. Microgale pusiUa, sp. n. 



Thesmallestof the Centetidse hitherto known. Coloration of 

 the fur like in M. longicaudata, viz. lighter than in M. Cowani 

 and M. Thomasi^ being light brown above, with a much 

 paler tinge below. Skull and dentition, apart from size, not 

 differing in any essential characters from the above-mentioned 

 species ; in the conformation of the anterior upper incisor 

 this new species agrees with M. longicaudata in having its 

 secondary cusp minute, whilst it is much larger in M. Cowani. 



Dimensions in millimetres of type (M. 1359), ^ : —

 neighbourhood of Vinanitelo, 27th May, 1896. Fossil in the 

 Children's Cave, near Sirab^ (Vakinankaratra). 



3. Eliurus minor^ sp. n. 



The smallest of the known species of this genus. General 

 colour brownish grey ; underparts fawnish. Proximal two 

 fifths of the tail scaly and almost naked, the brownish hairs 

 increasing in number and length towards the tip, with ten- 

 dency towards a distichous arrangement ; but the tail is far 

 from being so bushy as in E. myoxinus, Milne-Edw., the 

 type of which, by Prof. Milne-Edwards's kindness, I have 

 been able to examine in Paris. 



Measurements of type, skin (M. 494), $ : — 



Head and body circa 114 millim. ; tail circa 98. 



Basal length of skull 24*5 ; absolute length 29 ; length of 

 upper molars 4.

4. Eliurus tanala, sp. n. 



More closely related to E. Majori, Thos.*, than to the 

 other two species, but distinguished from the first by a some- 

 what larger size, by a slight difference in coloration — the
