EDENTATA. 163 



Cachicamus, Cuv. 



Which has only seven teeth on each side, and in each jaw. The 

 muzzle is pointed $ the tail long, and encircled with bony rings. 



Dasypus novemcinctus, L.j Cachichame, BufF. X, xxxvii ; Ta- 

 tou d longue queue, Id. Supp. Ill, Iviii ; Tatuete, Schreb. Ixxiii ; 

 Tatupeba, Marcg. (The Nine-banded Armadillo.) With nine, 

 sometimes eight intermediate bands, generally blackish ; the 

 body fifteen inches in length, and the tail the same. 



Das. 7-cinctus; Schreb. LXXII ; Tatou mulet, Azzar. (The 

 Seven-banded Armadillo.) But seven bands, and is smaller ; its 

 tail also is proportionably shorter. Those of the 



Apara, Cuv., 



Have the toes of the Cachicami, and nine or ten teeth throughout. 

 Das. tricinctus, L. ; Tatou Jlpara, Marcg. ; Jlpar, Buff. ; Mafaco, 

 Azzar.; Schreb. LXXI, A. (The Three-banded Armadillo.) 

 Three intermediate bands ; tail very short, and the compart- 

 ments regularly tuberculated. By enclosing its head and feet be- 

 tween its plates, it possesses the faculty of rolling itself into a 

 complete ball, like certain species of Oniscus. It is from Para- 

 guay and Brazil, and is one of those found farthest to the south. 

 Size, middling. In other Tatous, such as the 



Encoubertus, Cuv., 



There are five toes to the fore feet, the three middle of which are 

 the longest. The greater part of their tail is covered with scales, 

 arranged in quincunx. There are nine or ten teeth throughout. In 

 this subdivision is 



Dasyp. sexcinctus and octodecimcinctiis, L. ; Encoubert and Cir- 

 quinson, Buff.;(l) Tatou poyou, Azzar.; Buff. X, xlii, and Supp. 

 Ill, xlii. (The Six-banded Armadillo.) Distinguished from all 

 the rest of the genu^ by having a tooth on each side in the in- 

 termaxillary bone. The shell has six or seven bands ; its com- 

 partments are large, smooth and angular ; the tail is of a mid- 

 dling length, and annulated only at the base ; there are five toes 

 to each foot. The Pichiy of Azzara resembles this species, 

 except that there are no intermaxillary teeth, that its posterior 

 shield is denticulated, and that the parts not defended by the 



(1) The Weasel-headed Tatou of Grew; Cirquinson of BufF.; Das. octodecimdnC' 

 tus, L., is the Encoubert, or Six-tjanded Jirmadillo , but Grew considered the rows 

 of scales on the croup as movable. If we count them we shall find but sixteen, 

 and his own figure exhibits no more.
