but the red moustache and beard are only beginning to

 same as in the previous animal, with the exception of the 

 armsj which are dark maroon-brown ; and the hair about

 animal. The following are some of the measurements of this

The skull measures 6"'95 from the occiput to the anterior 

 border of the premaxillary, with a width across the zygoma of 

 4*"75, and a maximum parietal width of 4'-12. The milk 

 canines and incisors are still present, but the front upper incisors 

 can be seen in their sockets to be very broad and large teeth, 

 the two permanent molars that are through being also very 

 large. There is as yet no trace whatever of a sagittal ridge, 

 and the temporal ridges from the orbits are still 3 inches apart 

 on the vertex. The orbits are moderately large and rounded, 

 and the interorbital area is nearly vertical, the nasals being 

 small. The muzzle is broad and directed forwards, almost 

 at right angles to the interorbital surface. The symphysis 

 of the lower jaw is deep. The front lower incisors are 

 through and serrated, and the penultimate molar is ap- 

 pearing through the alveolus. Purchased, 28th July 1879-
