little in common between the hyraces and the elephants, which respectively form 
the representatives of two groups as distinct from one another as is the Odd-toed 
from the Even-toed group of the typical Ungulates. The elephants have been 
enabled to survive to the present day by the development of a highly-specialised 
dentition, and, perhaps, also owing to their huge bodily size; while the small 
hyraces are sufficiently protected by their habits. 
The Hyraces. 
Suborder Hyracoidea. 
Family PROCA VIIDJE. 
The small animals now generally known as hyraces (from one of their 
scientific names) are so like Rodents in external appearance and habits, that in 
our translation of the Bible they are designated by the term coney, which belongs 
properly to the rabbit. 
This Rodent-like appearance is largely due to the circumstance that (as 
shown in the figure of the skeleton) their jaws are armed in front with long,

curved teeth, adapted for gnawing, and separated by a long gap from the teeth of 
the cheek-series. Their front teeth are, however, in reality very different, both in 
form and number, from those of the Rodent mammals. In the upper jaw there 
are a pair of incisor teeth, of semicircular form, and growing throughout life in 
the Rodent manner. Instead, however, of being chisel-like, they are triangular 
in section, and terminate in sharp points, their outer and inner front surfaces 
being covered with enamel, which is wanting on the hinder surface. In the lower 
jaw there are two pairs of front teeth, of which the outermost are nearly straight, 
with long conical crowns divided into three lobes; both pairs of these teeth are, 
however, rooted, and therefore quite unlike the continually-growing single pair of 
the Rodents. The cheek-teeth are seven in number on each side of both the upper 
and lower jaw; and in structure approximate to those of either the rhinoceros or
