 downward bending o£ the facial portion. 



Owing to the incomplete condition of the fossil, only a few 

 measurements can be given : —

 Length of the fossil skull, from the occipital crest to 



anterior portion of frontals as far as preserved 92-7 



Same distance in Hapalemur simus, Gray (Br. Mus. 1 884/10.

Greatest breadth of the brain-capsule between the tvio 



parieto-squamosal sutures, in the fossil 64-8

It thus appears that, whilst the fossil skull, in its part preserved, 

 was about one-third longer than Hapal. simus, the breadth of its 

 cranial capsule was almost double that of the last \ 



The foregoing short description gives all the important cha- 

 racters of this interesting fossil, which in my opinion clearly 

 assign its systematic position to be within the subfamily of 

 Lemurince, and would besides justify the establishment of a new 

 genus, haviug closer relation to Hapalemur than to any other 

 members of the subfamily. I refrain, however, for the present, from 

 giving a name to it, as there is some probability th;it more complete 

 and more adult specimens may before long come to hand. 



' The skull of Hapal. simus figured by Jentink (1. c.) is somewhat broader 

 than the one at my disposal.
