producing a large number (four to ten) of young at a birth, all the 
others having usually but one or two. 
The Peba Armadillo, 7. novemcincta (Fig. 67), is a well-known 
species, having an extensive range from Texas to Paraguay. It is 
replaced in the more southern regions of South America by a smaller 
species, with shorter tail, the Mulita (T. hybrida), so called from the 
resemblance of its head and ears to those of a mule. T. kappleri is 
a large species from Surinam. 
A rare Armadillo from Peru described under the names of Crypto- 
phractus pilosus and Praopus hirsutus, but which evidently belongs to 
Tatusia, is of some interest owing to the thick coat of hair with 
which it is covered. This animal appears to be closely allied to 
LT. novemeineta, from which it mainly differs by having the whole of 
the carapace covered with a thick coating of light brown, fine, but 
rather stiff hair, about an inch and a half in length. Similar hair 
is found on the cheeks, the proximal portions of the limbs, and 
(although less abundantly and shorter) on the under surface of the 
body. The cephalic shield, snout, feet, and the tail, with the 
exception of the root, are bare. The coating of hair on the back 
and sides completely conceals the carapace, except near the margin 
of the scapular region ; but by separating the hairs the bands and 
scutes are rendered visible.t 
In the Pleistocene cavern-deposits of Brazil have been found 
remains of 7. novemcincta, and also of T. punctata, which appears to 
be an extinct form nearly allied to 7. kappleri, but of somewhat 
larger size. 
Extinct genera.—In addition to remains referable to existing 
genera, the above-mentioned deposits have also yielded evidence 
of the former existence of extinct generic types of Armadillos, 
some of which attained very large dimensions. Of these Eutatus 
was a large form distinguished from all existing genera by the 
circumstance that the whole of the carapace was composed of mov- 
able bands, which were thirty-three in number. Dasypotherium 
was a still larger form, furnished with eight teeth, of which the 
second seems to have been larger than the others; this genus is 
regarded as connecting the modern Armadillos with the next one. 
The gigantic Chlamydotherium, the scutes of which are common in 
the Brazilian caves, is considered to have been as large as a 
Rhinoceros ; the carapace has several movable bands, but the teeth 
1 A single imperfect skin, brought from the province of Ceara in Brazil, indi- 
cates a very remarkable form of Armadillo, named by A. Milne-Edwards Sclero- 
pleura brunetti (Ann. Se. Nat. xvi. p. 8, 1872). The dermal scutes are said to 
be much less developed than in other members of the family, and confined to the 
sides, all the median portion of the back being clothed with a flexible hairy skin. 
The head is broad and short, the ears small and far apart. The tail is long, and 
almost entirely devoid of scutes. The feet are unknown.
