24G GEOGRAPHICAL ZOOLOGY. [i'aut iv. 



in south Texas, to 50' soutli latitude; o]i the plains of Patagonia, 

 The distribution of the genera is as follows : — Taiusia (5 sp.), 

 Las the range of the whole family from the lower Eio Grande of 

 Texas to Patagonia ; Prionodontes (1 sp.), the giant armadillo, 

 Surinam to Paraguf^y; Dasijpns (4 sp.), Brazil to Bolivia, Chili, 

 and La Plata; Xciiurus (3 sp.), Guiatia to Paraguay ; Tohjpcutcs 

 (2 sp.), the three-banded armadillos, Bolivia and La Plata; 

 Chlcanydoplwj'us (2 sp.), near ^lendoza in La Plata, and Santa 

 Cruz de la Sierra in Bolivia. 



Extinct Armadillos. — Many species of JJasijjJus and A'enurus 

 have been found in the caves of Brazil, together with many 

 extinct genera — Hoplopliorus, Euryodon, Hderodoii, Pachy- 

 thcrium, and Chlamydotlicriiun, the latter as large as a rhino- 

 ceros. Eutatus, alliad to Tohjpcutcs, is from the I'liocene de- 

 posits of La Plata.

The Aard-vark, or Cape ant-eater {Oryctcropus cnpcnsis) 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 Xorth-East 

 Africa and Senegal, that of the latter country perhaps forming a 

 third species (Plate IV. vol. i. p. 261). 



Extinct Oryctcrojwdidcc. — The genus Macrothcrium, remains of 

 •which occur in the jMiocene 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 jMiocene deposits of Greece.
