The canines are strongly developed in the stallions, in the mare they are small 
but present as well in the upper as in the lower jaw. A small p!' is present on the 
left side of the upper jaw of the old mare, and in a young stallion in which the 
last molar has not yet cut the gum the p' is present on both sides. It appears thus 
probable that these teeth are normally developed in all specimens but being function- 
less soon fall out. 
A young stallion from Njoro with a condyloincisive length of 585 mm. has a 
skull which is even larger than that measured above, although this was a' very fine 
middle-aged specimen, among the largest in the herd, and considerably bigger than 
an old stallion shot at the same time. In this young stallion from Njoro the per- 
manent dentition is not yet fully developed. The condition of the dentition is as 
follows. 
Upper jaw: 1' in use and worn.
