200 EDENTA TA 



Matico ; and T. muriei. Eemains apparently referable to T. conums 

 are of not uncommon occurrence in the Brazilian cavern-deposits. 



Subfamily Tatusiinae. This group contains but one genus, 

 Tatusia. 1 Teeth -| or f , very small subcylindrical. The first and 

 second subcompressed, the last considerably smaller than the others. 

 They present the remarkable peculiarity (elsewhere found among 

 Edentates, so far as is yet known, only in Oryderopus) of all being, 

 with the exception of the last, preceded by two-rooted milk teeth, 

 which are not changed until the animal has nearly attained its full 

 size. Vertebrae : C 7, D 9-11, L 5, S 8, C 20-27. Head narrow, 

 with a long, narrow, subcylindrical, obliquely -truncated snout; 

 pterygoids meeting in the middle line below the nasal passage. Ears 

 rather large, ovate, and erect, placed close together on the occiput. 



FIG. 67. The Peba Armadillo (Tatusia novemcincta). 



Carapace with seven to nine distinct movable bands ; sculpture on 

 scutes consisting of pits arranged in a V-shape. Body generally 

 elongated and narrow. Tail moderate or long, gradually tapering ; 

 its dermal scutes forming very distinct rings for the greater part of 

 its length. Fore feet with four visible toes, and a concealed clawless 

 rudiment of the fifth. Claws all long, slightly curved, and very 

 slender, the third and fourth subequal and alike, the first and fourth 

 much shorter. Hind feet with five toes, all armed with strong, 

 slightly curved, conical, obtusely-pointed nails. The third longest, 

 then the second and fourth; the first and fifth much shorter than 

 the others. 



This genus differs from all the other Armadillos in having a pair 

 of inguinal mammae, in addition to the usual pectoral pair, and in
