shell are furnished with longer and more thickly set hairs. A 
neighbouring species is the Hairy Tatou of Azzara, A third 
subdivision of the Tatous, or the 
Caxassous, Cuv., 
Has five toes to the fore feet, but directed obliquely, so that the 
thumb and index are slender, and the latter the longest; the middle 
one has an enormous trenchant nail; the following one has also a 
nail, but a shorter one, and the last toe is the shortest of all. This 
form of the foot enables these animals to divide the earth, and bur- 
row into it with rapidity, or at any rate to cling to it with such 
tenacity that it is extremely difficult to tear them fromit. They 
have but eight or nine teeth on each side, and in each jaw.” 
Das. unicinctus, L.; Le Cabassou propre, Buff.; Tatouay, Azz. 
(The Tatouay.) Twelve intermediate bands ; the tail long and 
tuberculous ; the compartments of the bands and shields 
square, broader than long; five toes every where, of which the 
four anterior have enormous nails with trenchant external 
edges. It attains a great size. 
Priopon, Fr. Cuy. 
The toes more unequal, and the nails more enormous than in the 
preceding subgenus ; twenty-two to twenty-four small teeth through- 
out, or ninety-four or ninety-six in all. Such is the 
Dasypus gigas, Cuv.; Tatou géant, Geoft.; Great Tatou, Azzar.; 
Deuxieme Cabassou, Buff. X,xlv. (The Giant Armadillo.) Twelve 
or thirteen intermediate bands; the taillong, and covered with 
‘tiled scales ; the compartments square, more broad than long. 
It is the largest of the Tatous, being sometimes more than three 
feet in length, exclusive of the tail. 
Finally, we should place after the Tatous, as a very distinct sub- 
genus, the 
Cramypuorus, Harl., 
Which has ten teeth throughout, and five toes to each foot; the 
nails of the fore feet very large, crooked and compressed, furnishing, 
as in the Cabassous, a powerfully trenchant instrument. The back 
is covered with a suite of transverse rows of scaly plates, without 
any solid shell before or behind, forming a sort of hauberk which is 
only connected with the body along the spine. The hinder part of 
the body is truncated, and their curved tail partially attached to the 
under part of the body.(1). One species only is known, the 
(1) We only know this animal by the description of Dr Harlan, Ann. of the New 
York Lyc. I, p. 235 and pl. xxi.
