in south Texas, to 50° south latitude on the plains of Patagonia. 
The distribution of the genera is as follows : — Tatusia (5 sp.), 
has the range of the whole family from the lower Bio Grande of 
Texas to Patagonia ; Prionodontes (1 sp.), the giant armadillo, 
Surinam to Paraguay; Dasypus (4 sp.), Brazil to Bolivia, Chili, 
and La Plata ; Xenurus (3 sp.), Guiana to Paraguay ; Tolypeutes 
(2 sp.), the three-banded armadillos, Bolivia and La Plata; 
Chlamydopkorus (2 sp.), near Mendoza in La Plata, and Santa 
Cruz de la Sierra in Bolivia. 
Extinct Armadillos. — Many species of Dasypus and Xenurus 
have been found in the caves of Brazil, together with many 
extinct genera — Hoplopliorus , Euryodon , Heterodon , Pachy - 
thermm, and CMamydotherium , the latter as large as a rhino- 
ceros. Eutatus, allied to Tolypeutes , is from the Pliocene de- 
posits of La Plata.

The Aard-vark, or Cape ant-eater (Orycteropus ccipensis) is a 
curious form of Edentate animal, with the general form of an 
ant-eater, but with the bristly skin and long obtuse snout of a 
pig. A second species inhabits the interior of North-East 
Africa and Senegal, that of the latter country perhaps forming a 
third species (Plate IV. vol. i. p. 261). 
Extinct Orycteropodidce. — The genus Macrotherium, remains of 
which occur in the Miocene deposits of France, Germany, and 
Greece, is allied to this group, though perhaps forming a sepa- 
rate family. The same may be said of the Ancylotherium, a 
huge animal found only in the Miocene deposits of Greece.
