580 ZOOLOGY. 
maxillary glands are very large, so that the viscid salivary 
fluid is very abundant. They burrow into ant-holes, thrust- 
ing the tongue among the ants, which stick in multitudes to 
the viscid, writhing rod, and are withdrawn into the mouth. 
The pyloric end of the stomach is gizzard-like. The ant- 
eaters (Myrmecophaga) inhabit South America. 
The pangolins, or species of Manis, are mail-clad ant- 
eaters, the body and long tail being covered with large 
overlapping scales. When molested they roll up the body. 
In walking the hind feet rest on the soles, while the fore- 
feet are supported by the upper side of the long bent 
claws.

The long-tailed pangolin of the West Coast of Africa (Fig. 
501) tears open with its long claws the nests of the white 
ants. It is nearly 3-metre (28-30 inches) in length. 
The armadillos (Fig. 502) are small mammals covered with 
a carapace, consisting of from three to thirteen transverse 
rows of movable scales ; by rolling into a ball, these singu- 
lar creatures become thoroughly protected from their ene- 
mies. Dasypus novem-cinctus Linn. is much like the Peba 
armadillo, and extends from South America to Texas. The 
strange extinct armadillo-like Glyptodon of South Amer- 
ica, which was over two metres (8 feet) long, was covered
