Tall. This part of the 

 great Armadillo is gently curv- 

 ed with the concavity upward, 

 and consists of caudal verte- 

 brae enclosed in an inflexible 

 sheath composed of closely 

 united dermal plates of various forms and sizes, but disposed in a regular and 

 beautiful pattern. The armor is joined to the internal skeleton of the tail, and 

 the larger plates increase in size as they approach the end of the tail, which is 

 enclosed by a pair something like a bivalve shell. The relation of the endo- and 

 exo-skeletons is finely shown in the specimen. The original, from the Pampas 

 of Buenos Ayres, is in the British Museum. Size, 39 x 9. Price, $8.00.
