MR. ST. G. MIVART ON THE LEMURS. [May 20, 



Fig. 8.

Dorsal aspect of right manus of Lepilemur mv.sfelinus. 



of the LemurincB in developing a sagittal ridge, and in not having the 

 glenoid surface concave transversely and protected externally by a 

 depending zygomatic process. 



On the other hand the condyle of the mandible has its articular 

 surface quite remarkably prolonged downwards behind the ascending 

 ramus, though the prolongation is much broader relatively (fig. 4, 

 p. 488) than in the Indrisince, and is an exaggeration of what is to 

 be seen in Hapalemur. The internal condyle of the humerus is 

 perforated ; and the fourth digit is the longest, both in the manus and 

 in the pes. 



Thus Lepilemur seems to be that genus of the Lemurince which 

 most approximates to the Indrisince. 



It shows some affinities to the Cheirogalei, notably in its elongated 

 naviculare ; but it is also somewhat closely related to Hapalemur. 



The last-named genus is now represented in the British Museum 

 by a skeleton of Hapalemur simus. 



I find that this skeleton quite agrees with that in the Paris col- 

 lection, before noticed by me*, except that the spine of the axis is 

 backwardly produced.
