NOMARTHRA. 751 
3. Myrmecophagide—the Ant-eaters, hairy animals, without even 
traces of teeth, with long thread-like protrusible tongue, viscid 
with the secretion of greatly enlarged submaxillary glands. 
One form, Alyrmecophaga jubata, is terrestrial ; the others, 
belonging to the genera Zamandua and Cycloturus, are 
arboreal. All feed on insects. All are Neotropical. The 
skull is long ; the third finger is greatly developed, the others 
are small; the pes has four or five almost equal clawed toes ; 
the clavicles are rudimentary ; the tail is long and sometimes 
prehensile. The brain is well convoluted. The uterus is 
simple: the placenta is dome-like or discoidal. 
4. Dasypodidee—the Armadillos, all S. American except 7atusia 
novemcincta, which extends as far north as Texas. They are 
nocturnal, omnivorous animals, able to run and burrow rapidly. 
They are unique among living Mammals in having a dermal 
armature of bony scutes united into shields and rings, and 
covered by horny epidermis. The teeth are numerous, simple, 
and of persistent growth. Clavicles are well developed. The 
digits have strong claws or nails. The brain has large olfactory 
lobes; the cerebral hemispheres have few convolutions. 
The tongue is long and protrusible, and the submaxillary 
glands are large. The stomach is simple. The uterus is 
simple; the placenta is discoidal and deciduate, except in 
Dasypus. 
Examples.—Dasypus, Chlamydophorus, Tatusia. 
5. Glyptodontidae—extinct Pleistocene types, mostly S. American, 
but represented in Mexico and Texas. The body was often 
huge, and was covered by a solid carapace of great strength. 
Order NOMARTHRA 
1. Manide—the Ethiopian and Oriental Pangolins, covered dorsally 
with overlapping horny scales, They are terrestrial, burrow- 
ing animals, but sometimes climb trees. They usually feed 
on termites. Teeth are rudimentary, the tongue is long 
and protrusible. The uterus is bicornuate; the placenta 
diffuse and indeciduate. There is one extant genus, 
Manis. 
2. Orycteropodidee—the Ethiopian Aard-varks, represented by two. 
species of Orycteropus, ranging from S. Africa to Egypt. They 
are shy, nocturnal animals, living in burrows, feeding on 
termites. There are numerous complex teeth, differing in 
structure from those of any other known Mammal. The 
skin bears scanty bristles.) The mouth is tubular, and the 
tongue is narrow and protrusible. The digits bear nails 
suited for digging. The uterus is bicornuate, the placenta 
broadly zonary. The relation to the other Edentates, or, 
indeed, to other Mammals, is uncertain,
