quite the same, it is readily distinguishable from that species by- 

 its larger size, smaller ears, very much shorter tail (see dimensions 

 below), and its proportionally shorter feet and shorter fifth toes. 

 The naked Hue on the underside of the muzzle is also narrower 

 than in M. longicaudata, and has no additional median groove.

All the specimens of both species vf ere obtained by Mr. Cowan 

 in the Aukafana forest. Eastern Betsileo, between the middle of 

 February and the middle of March, 1880. This time of year 

 being, in Madagascar, the autumn, and therefore not the breeding- 

 season, I have been unable to make out the number of mammae, 

 or any other characters connected with the sexual organs. 



Microgale differs from Geogale, a genus recently described by 

 Prof. A. Milne-Edwards t, by the quite different shape of its skull 

 and teeth, and by the much larger number of the latter. 



This genus is an extremely interesting one, as adding another 

 connecting link between Centetes and Potamogale, agieeing with, 

 the former in the possession of a clavicle and lacrymal canal, and 

 with the latter by its long tail, soft fur, and united tibia and 

 fibula. I am indebted for a knowledge of the correct position of
