new Mammals from Madagascar. 321 



4. Microgale longtrostris, sp. n. 



In coloration like M. Thomasi. Muzzle much produced 

 and attenuated. Whilst in the last-named species, as well as 

 in M. longicaudatus and M. Gowani^ the contour of the skull 

 is cylindrical, it is somewhat pyriform in shape in the present 

 species, the cerebral cranium being comparatively broader, 

 the facial cranium slenderer and more elongated, the latter 

 character applying as well to the lower jaw, which is slenderer 

 and more attenuated than in either M. longicaudatus or 

 M. Cowani. The dentition is weaker than in AT. Cowani, 

 the secondary cusps more reduced than even in M. longi- 

 caudatus. Hind foot remarkably long. 



Dimensions in millimetres : — 



Length of head and body 69 ; length of tail 54; length of 

 manus 9 ; length of pes 18*5 ; length of ear 14*5. 



Type and only specimen, ? (M. 490), a dry skin^ with 

 the skeleton complete, from the neighbourhood of Ampi- 

 tamb^, 4th July, 1895. 



Local naxnes foi'imenjg, rainijora. 



5. Oryzoryctes gracilis, sp. n. 



Coloration of the skin as in 0, tetradactylus, M. Cowani, 

 &c. The claws of the pentadactyle manus smaller and less 

 curved than in 0. tetradactylus. Though the skull is longer 

 than in M. Thomasi, its frame is much more slender, and by 

 the elongation of the facial cranium and lower jaw, as well 

 as by the delicate teeth, it very much recalls the skull of 

 Hemicentetes in miniature. The anterior upper and lower 

 premolar separated by a wider interspace from both the 

 canine and the second premolar than in any other known 

 member of the family, Hemicentetes and Centetes excepted. 

 This remark applies as well to the two outer upper and 

 the last lower incisor, with regard to the teeth immediately 

 preceding and following them. The outer margins of the 

 upper molars are more deeply notched than in all other known 

 Centetidee.
