314 THE GEOGRAPHY OF MAMMALS 



this sub-family, is the largest Armadillo known, measuring 

 about three feet in the length of its body: it inhabits 

 the forests of Guiana and Brazil. The three species of 

 Tolypeutes, which have the power of rolling themselves 

 up into a ball like a Woodlouse, are restricted to the 

 pampas of Argentina and Bolivia. The members of the 

 two other genera of Dasypodinre (Dasypus and Xenurus) 

 range from Guiana to Patagonia, but are mostly met with 

 in the south. 



Of the third sub-family (Tatusiinie), distinguished 

 from the rest of the group by the peculiar structure of 

 the fore-feet, five species, all belonging to the genus 

 Tatusia, are known. One of these, the Peba Armadillo, 

 passes up through Central America into Texas, and is also 

 widely distributed throughout South America down to 

 Paraguay. Another species of this genus, T. hirsuta, dis- 

 tinguished by its thick covering of hair, occurs in Western 

 Peru, and the remainder are found in different parts of 

 South America. 



The very curious Armadillo, described in 1872 by M. 

 Milne-Edwards {Nouv. Arch. d. Mus.,Vn., p. 177, 1871) from 

 an imperfect specimen as Scleropleura bruneti, is from 

 the province of Ceara, North Brazil. It should apparently 

 form a sub-family of itself. 



Section III. — Distribution of the Old World 

 Edentates 



The Old World mammals, placed in the Order of 

 Edentates, perhaps more from the want of a better position 

 for them than for any other reason, belong to two families 

 — the Maniidze, or Pangolins, and the Orycteropodidm, or
