have belonged to the same species as that described in the paper. 
An allusion was also made to some portions of bony armour ob- 
tained in the Rio Seco, in the Banda Oriental, and similar in struc- 
ture to the specimen of the Pedernal. One of the portions was 
the covering for the tail. It was hollow to its extremity, and pre- 
sented in its concavity, vestiges of caudal vertebre very distant from 
each other. 
In conclusion, Mr. Owen observes, that having brought together 
evidence of the remains of five specimens (found in the Rio Seco, 
Rio Janeiro, Villaneuva, Pedernal, and the Banda Oriental) of a 
large Edentate species undoubtedly covered with armour, and more 
or less corresponding with the characters of the Glyptodon, and 
having established the characters of that genus on both dentary and 
locomotive organs; he trusts that he has at the same time vindicated 
the opinion of Cuvier with reference to the Megathere, by proving 
it to be, by its tegumentary covering as well as its osseous system, 
more nearly allied to the Ant-eaters and Sloths than to the Ar- 
madillos.
