ments below, and the third true molar is as large as the first. The 

 upper surfaces of all the teeth, molars and premolars, are much worn 

 by attrition, presenting a nearly flat surface (PI. XVI. fig. 2) ; and in 

 each tooth the enamel has been worn through so as to expose in each 

 premolar one area of dentine, in the first true molar four rather 

 large areas, in the second four smaller ones, and in the third or last 

 molar two, perhaps three, such areas. The enamel of the crowns 

 seems to be very thick, but this is due in some measure to the con- 

 dition of wearing.

The femora are both preserved, but are much damaged ; that of 

 the left side is the more perfect (PL XVI. figs. 6 & 7), although 

 its greater trochanter and part of the head are broken away; 

 the shaft is so much denuded, especially in the middle, that its 

 diameter cannot be accurately measured : it seems to have been 

 about 30 millim. from side to side and 25 from back to front, ex- 

 cluding the linea aspera. The distal articular condyles are denuded 

 externally and internally, so that their width is uncertain ; their 

 antero-posterior extent is found to be 62 millim. The greatest 

 length of the femur is about 16| inches (419 millim.). The shaft 

 is nearly straight, being only slightly convex forwards. The articular 

 head is comparatively large, its vertical diameter being 48*5 millim. 

 The shaft and neck of the bone are rather flattened from before 

 backwards ; but the long axes of these two portions seem to be at 

 the usual angle with each other. The upper part of the shaft, 

 however, is twisted upon itself, so that the neck and head are 

 turned more forward than usual ; the exact amount of this torsion 

 cannot be measured, on account of the imperfection of the distal
