which occur in South America along with Glyptodon. Schisto- 

 phurmn typus was eight feet long, including the tail; and 

 the carapace is three feet in height. 



N"o direct representatives of the Glyptodons are known to 

 exist at the present day; but the true Armadillos (fig. 615), 

 with a variable number of movable bands in their dorsal 

 armour, appear in both the late Pliocene or Post-Tertiary 

 accumulations of the great plains of Soutli America and also 

 in the cave-deposits of Brazil. Some of these forms belong 

 to well-known living generic or sub-generic types, such as

Dasyjms, Xenums, and Eutatus ; while others are referable 

 to extinct and comparatively gigantic forms, such as Clilamy- 

 dotlierium, Pachytlierium, &c. Of these, ChlcvmydofJierium 

 attained a size equal to that of the existing Ehinoceroses. 



Lastly, the South American Ant-eaters {Myrmeccrphagidm) 

 are represented in the cave-deposits of Brazil by tlie extinct 

 Glossothermm.
