It is still a debatable question wbat position the Hyrax should occupy in a 
systematic list of Mammalia. Most of the anatomical characters are peculiar, but 
the pattern of the molar teeth, resembling closely that of the Rhinoceroses, seems 
to point to kinship between the two groups. Up to the present time, however, 
palaeontology has thrown no light on the affinities of these animals. The dentition 
generally accepted is : incisors canines premolars molars | = 34 teeth. 
The upper incisors have persistent pulps, and are curved longitudinally, forming a 
semicircle as in Rodents, but their apices are sharp-pointed instead of chisel-shaped. 
There is a long diastema between the incisors and the molar series of both jaws. 
There are five toes on the fore feet, but only three on the hind feet: they are shod 
with short broad nails, with the exception of the inner toe of the hind foot, which has 
a peculiar long curved claw. 
The size is about that of the Hares, but the form is heavy and robust. The tail 
rudimentary. The hair short, thick, moderately harsh, with scattered, longer, bristle¬ 
like hairs over the greater part of the body. A glandular area, covered with adpressed 
modified hairs, on the middle of the back. Tbe ears are very short.
