THE SYRIAN HYRAX.

have the greatest number after the Hyrax, belong 
precisely to this order of Pachydermes with 
which we wish to range them. The Elephant and 
Tapir have each twenty, the Rhinoceros nineteen, 
and the Solipedes, which approach nearest the 
Pachydermes, eighteen ; while the most of the 
Rodentia, on the contrary, have but twelve or 
thirteen, the Beaver alone having fifteen.* 
In the structure of the head it resembles the 
Pachydermes. The maxillary bones are very 
distinct from those of the Rodentia by the small 
size of the suborbital hole, which in the latter is 
enormously large. There are four lower incisive 
teeth, while the two above are not bent and trun- 
cated, but are triangular and pointed, and re- 
semble those of the Hippopotamus. The other 
teeth also differ from those of the Rodentia ; the 
condyle of the jaw is also different, permitting 
the motion from right to left. This will be illus- 
trated on the accompanying plate of Skull and 
dentition of Cape Hyrax. Plate XV. 
The number of toes in the Hyrax is four before 
and three behind, as in the Tapir. They are 
united by the skin to the very nail, as in the 
Elephant and Rhinoceros, and represent those of 
the former animal, both in their figure and in the 
manner in which they are placed upon the foot, 
Ossemens Fossilles.
