of their two or three fingers and toes, and from their slow 
movements they get the term, Sloth. Their long bones are 
peculiar, being solid structures, having no marrow cavity. 
Their food consists of leaves. They hav e but a small 
number of teeth, and these are remarkable, because they are 
constantly growing, and never form roots, and there are no 
milk-teeth. In structure also their teeth differ from those of 
ordinary mammals. The group of sloths includes those 
mammals in which there is a variation in the number of the 
neck vertebrae, some having nine and others seven or six 
bones in the neck, whereas seven is the normal number in 
mammals, as previously mentioned. The stomach of some 
of the sloths is much complicated, and in this respect it 
resembles the stomach of the ruminants, and when their 
exclusively vegetable diet is borne in mind, it would appear 
that such nourishment requires a number of special cavities 
for its proper digestion. 
The Ant-eaters are represented in Asia by one genus, 
viz., the Scaly Ant-eaters or Pangolins, which occur also 
in Africa, but besides these animals the insect-eating 
Edentata include two other remarkable-looking large ani¬ 
mals, viz., the Aard-Vark or Ant-eater of South Africa, and 
generally known as the Cape Ant-eater ; and the Great 
Ant-Bear of South America. 
The Scaly Ant-eater, Manis pentadactyla, inhabits the 
drier regions of India, from the Terai to Cape Comorin. 
Another species, Manis anrita, occurs on the slopes of the 
Himalaya, ascending to 5,000 or 6,000 feet, and extends into 
China and Burma; but in the latter country another species, 
Manis javanica , is also found. They have attenuated forms ; 
their heads are much elongated and pointed; their 
ears are small, and their tails broad and flat below,
