up an ant's nest. In captivity these armadillos will eat fruit and green vegetables; 

 although, on account of the small size of their mouths, it is necessary that all the 

 food with which they are supplied should be chopped up into small pieces. Fossil 

 remains of armadillos of this species, together with others belonging to all the 

 genera except Priodon, are met with in the cavern deposits of Lagoa Santa, in 

 Brazil, and are mostly referable to species still existing in the country. 



The peba armadillo (Tatusia novemcincta) , ranging from Texas to 

 dill Paraguay, together with the mulita "little mule" ( T. hybrida), 



of Argentine and other parts of South America, and certain allied spe- 

 cies, differ from all the members of the family yet noticed by the elongated ears 

 being closely approximated at their roots, by the female having a pair of teats on 

 the abdomen, in addition to the two on the breast, and by the circumstance that 

 the permanent teeth, with the exception of the last pair in each jaw, are preceded 

 by deciduous milk-teeth, each furnished with two roots. The permanent teeth,

which are either seven or eight in number in each side of both the upper and lower 

 jaws, are very small in proportion to the size of the skull, and do not come into use 

 until the animal has well-nigh attained its full dimensions. The head is narrow, 

 and produced into a nearly cylindrical snout, obliquely truncated at the extremity; 

 and the bony palate of the skull has a backward prolongation formed in the same 

 manner as that of the great ant-eater. The body is long and narrow, with from 

 seven to nine movable bands between the scapular and lumbar shields; the former 

 being produced on either side of the shoulders, and having a deep notch at the neck. 

 Bach bony plate is ornamented with a series of pits arranged in the shape of a V. 

 The tail is nearly or quite as long as the body, and surrounded for the greater part 

 of its length with complete bony rings. The fore-feet have four long claws, of 

 which the inner pair are considerably larger than the others; while the hind-feet 

 carry five claws, of which the third is the longest, and the fourth and fifth the short- 

 est. The length of the body of the peba armadillo is about sixteen inches, and that 

 of its tail some two inches less. In producing from six to twelve young at a birth 

 the peba armadillo differs from all the species hitherto noticed. It inhabits burrows
