MAMMALIA.

Extinct Bradypodidoz. — In the caves of Brazil are found three 

 extinct genera of Sloths — Ccclodon, Sphenodon, and Ochotherium. 

 More distantly allied, and probably forming distinct families, 

 are Scelidotherium and Megatherium, from the caves of Brazil 

 and the Pliocene deposits of La Plata and Patagonia. 



Family 72.— MAMD1D.E. (1 Genus, 8 Species.) 



The Manididae, or scaly ant-eaters, are the only Edentate 

 Mammalia found out of America. They are spread over the 

 Ethiopian and Oriental regions ; in the former from Sennaar to 

 West Africa and the Cape ; in the latter from the Himalayas to 

 Ceylon, and Eastward to Borneo and Java, as well as to South 

 China, as far as Amoy, Hainan, and Formosa. They have been 

 sub-divided, according to differences in the scaly covering, into 

 five groups, Manis, Phatagin, Smutsia, Pholidotus and Pangolin, 

 the three former being confined to Africa, the last common to 

 Africa and the East, while Pholidotus seems confined to Java. 

 It is doubtful if these divisions are more than sub-genera, and 

 as such they are treated here. 



No extinct species referable to this family are yet known. 



Family 73.— DASYPODID^. (6 Genera, 17 Species.) 



General Distribution. 



The Dasypodidse, or armadillos, are a highly characteristic Neo- 

 tropical family, ranging from the northern extremity of the region
