Dr. Fitzinger, in the ' Sitzungsbericht,' 1871, p. 335, describes as 

 separate species, Dasypus peba, D. urocerus, D. Lundii, and D.

 hirsutus of Brnmeister, but he only knows them from books. 



In a very young specimen (113 c) in the Britisli Museum the head 

 is covered with naked skin, the shields not being developed. The 

 dorsal zones are imperfectly developed, of about fifty-two tesserce ; six 

 zones are complete, and the hinder ones are only developed on the 

 side of the back. The rings of the tail are each formed of two series 

 of shields, and far apart. 



-'' The lachrymal bone subtr {angular. The lower edge just above the
