THE MALAYSIAN UNGULATES. 
The antlers of deer, however, may be described as a 
development of dead bone carried foT a time and periodically 
shed by the living animal. The bony pedicles of “ budding " 
antlers form part of the skull itself and are at first covered 
with ski ik which covers the newly formed antler and on ac- 
count of its fine hairy texture is known as the “ velvet” The 
blood vessels of the velvet become constricted at the “ burr M 
dose to the skull; the “velvet” then dries up and is rubbed 
off. The antlers are then ready for fighting. After the pair- 
ing season they are shed. 
The third type of horn is hollow, but permanent. It 
grows on a bony protuberance of the skull and is like the horn 
of the rhinoceros a modified growth of the skin tissues. 
Tlie distinctions between the three Sub-Orders into which 
Malaysian Ungulates can be separated have already been in- 
dicated above. The following key shows these differences at 
a glance : — 
a A long flexible trunk . . . . . . Froboscidea. 
at No long flexible trunk. 
b Number of toes odd (except 4-toed fore feet 
of Tapir) . . . . . . . . Perissodcctyla. 
fei Number of toes even, . , . , . . Artiodactyla.
