This species (according to De Blainville’s figure) differs from all 
the other Microcebi, except M. smithii, in having the first upper 
premolar less vertically extended than is the second, and in the 
greater forward production of the preemaxillze and nasals. According 
to M. Gervais’s figure (Mammiféres, p. 173), it also differs in the 
greater equality of the upper incisors.

I have no knowledge of the cranial or tarsal structure of this species, 
or of the position of its gall-bladder. The first upper premolar is 
canine-like.
