Matico ; and 7. mwrici. Remains apparently referable to 7. conurus 
are of not uncommon occurrence in the Brazilian cavern-deposits. 
Subfamily Tatusiine.—This group contains but one genus, 
Tatusia.1 Teeth £ or 4, 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 Orycteropus) 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. Vertebree: C7, D 9-11, L5, 88, C 20-27. Head narrow, 
with a long, narrow, subeylindrical, 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. 
Fic. 67.—The Peba Armadillo (Tutusia 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 ‘ot 
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, obtuscly-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 mamme, in addition to the usual pectoral pair, and in
