In. the fragment of the skull the orbits are directed straight 

 forward, and, although their hinder portion is broken, clearly show 

 that they were separated from the temporal fossae by a bony wall. 

 The lachrymal foramen is situated within the margin of the orbit. 

 The inner upper incisors are in contact in the middle line. The 

 nasals are concave in profile, and the facial profile is steep. 



The above characters, together with the pattern of the molars, 

 are the very opposite of what we find in Lemuroidea, whilst they 

 are as positively evidence that the fossil belongs to the Anthropoidea. 

 The uasals are broad, and so is the whole of the interorbital region ; 

 its transversal diameter almost equalling that of the orbits, and 

 therefore exceeding what obtains in the genera of Anthropoidea, 

 which show the maximum of latei'al extension of this region 

 (Mycetes, Hylobates, Homo). This is about the only point in 

 which the fossil approaches some of the Lemuroidea.

The dental formula of the upper jaw is as follows : 1 2, C 1, P3, M 3. 



Only the molars, premolars, canine and the outer incisor of the left 



side are preserved, the other teeth being broken down to their sockets; 



those preserved are very much worn. The internal pair of upper
