instead of near its middle. Another peculiarity of the skull is the absence of any 
postorbital process defining the hinder border of the socket of the eye, which is 
consequently continuous with the temporal fossa, or large open space at the side of 
the hinder portion of the skull. Then, again, the lower jaw is very long and 
slender, with an extremely short union in front between its two lateral branches, 
and without the process which usually ascends behind the socket of the eye for the 
attachment of the muscles of mastication. Like the sloths, the females of the great 
ant-eater have but a single pair of teats on the breast. 
Distribution and Although distributed over the whole of the tropical portions of 
Habits. South and Central America, the great ant-eater is nowhere common ; 
and from its nocturnal habits but seldom seen. It frequents either the low, wet 
lands bordering the rivers, or swampy forests; and is strictly terrestrial in its 
habits. Its strong claws might lead to the supposition that the creature was a 
burrower, but this is not the case. It has, however, usually a regular lair, or at 
least an habitual place of resort, generally situated among tall grass, where it 
spends the day in slumber, lying on one side, with its head buried in the long fur 
of the chest, the legs folded together, and the huge tail curled round the exposed 
side of the body. Except in the case of females with young, the ant-eater is, as a 
rule, a solitary creature. Its usual pace is a kind of trot, but when pursued it 
breaks into an awkward, shuffling, slow gallop. The food of the great ant-eater 
consists exclusively of termites and ants, together with their larve. In order to 
obtain these insects, the ant-eater tears open their nests or hillocks with the power- 
ful claws of its fore-feet. As soon us the light of day is let into their domicile, the 
ants or termites rush to the surface in order to investigate the cause of the dis- 
turbance, and are forthwith swept up by hundreds adhering to the viscid tongue 
of the ant-eater, which is protruded and withdrawn with lightning-like rapidity. 
The breeding-habits of the animal are still very imperfectly known. A 
single young is, however, produced by the female in spring, which is carried about 
on the back of its parent for a considerable time. The period of suckling lasts for 
several months; and even when the young ant-eater has taken to feeding on 
insects, it does not leave its parent until she is again pregnant. 
Usually the ant-eater is a harmless, inoffensive creature, which may be driven 
in almost any direction so long as it is not pressed too hard. If, however, driven 
to close quarters, it turns furiously on its assailants, whom it attacks by hugging 
with its immensely muscular arms. It has been asserted, on the authority of the 
natives, that the ant-eater will even face and attack the jaguar; and although the 
truth of this statement was denied by the traveller Azara, a later explorer believes 
that it may be founded on fact. Like the sloths, ant-eaters are exceedingly difficult 
to kill, their skin being so tough that an ordinary small hunting-knife will make 
no impression on it, while their skulls may be battered with a heavy stone without 
producing any other effect than temporarily stunning the creatures. 
These ant-eaters thrive fairly well in captivity in Europe; but spend most of 
their time in sleep, with the head, limbs, and tail folded up in the manner already 
mentioned, On awakening, the animal generally unfolds itself with considerable 
deliberation, usually sitting up at first on its hind-quarters, with its legs stretched 
out rigidly in front, and its bird-like head swaying slowly from side to side. “In
