DESCRIPTION OF A NEW SPECIMEN OF GLYPTODON 555 
phalanges is thicker on one side than on the other, so that the upper 
surface, which is convex from side to side, and also from before 
backwards, slopes from the thick towards the thin edge. 
The distal phalanx of the second digit has its thick edge on its 
ulnar side, but all the others have their thick edges radial. The 
distal phalanx of the fifth digit is more pointed, smaller, and thicker 
in proportion than the others. 
The hind foot is quite normal in structure, possessing five toes 
and the regular number and disposition of tarsal, metatarsal, and 
phalangeal bones. The third or middle digit is the longest, and its 
distal phalanx is the longest of all. It is nearly square, and its outer 
and inner edges are almost equally thick. The distal phalanges of 
the other toes are all thicker on the side turned towards the middle 
toe. That of the second toe is almost as square as that of the third ; 
but the distal angles of that of the third and fourth are bevelled off 
on the fibular side, while the terminal phalanx of the hallux is 
similarly bevelled off upon the tibial side. The metatarsal bones 
have the same thick, prismatic form, and the proximal phalanges the 
same discoidal character as in the fore foot. 
The calcaneal process is directed outwards at an angle of 45° from 
the axis of the foot, and must have been much raised in the natural 
position. 
While the work of restoration, whose results have just been briefly 
detailed, was going on, we learned from Dr. Falconer that a nearly 
entire specimen of a Glyptodon was exhibited in the Museum at 
Turin. An application was at once made to the authorities of the 
Museum for information, and, if possible, for photographs of this 
skeleton, and was responded to with the most obliging readiness. 
These photographs of a skeleton in some respects more, in others 
less perfect than that of the College, have confirmed the conclusions 
already arrived at in the most satisfactory manner; and I trust 
before long to be in possession of descriptive details of parts of this 
specimen which are wanting in our own, and which will enable me 
to complete the anatomy of the skeleton of the gigantic extinct 
Armadillo.
