116 Megatherium of Georgia. 



the third either the last dorsal or the first lumbar. None of 

 these are entire. 



A fragment undetermined, but supposed to be of the ilium. 



Eight pieces belonging to three or four different ribs. 

 Three of these pieces have the heads attached to them, and 

 two seem to have belonged to the left side, and the remainder 

 to the right. 



The head of the lower extremity of the humerus, with both 

 condyles nearly entire. 



Two pieces with a concavity at one end, perhaps the superi- 

 or parts of a radius and ulna. 



A bone supposed to be a tarsal, much broken. 



Two carpal bones adapted to each other. 



The heads of both femora ; and a fragment, apparently the 

 lower condyle of a femur. 



Part of a bone about seven inches long, supposed to be part 

 of a fibula. 



Besides these were four or five other small pieces of bone, 

 but so imperfect as not to be easily referred to their proper 

 places in the skeleton. 



In addition to the foregoing should be enumerated the two 

 fragments of teeth from which professor Mitchill drew up his 

 description. On being compared with Dr. Habersham's col- 

 lection, one of them was found to correspond with a fragment 

 supposed to be of a. fourth molar, of which it formed the poste- 

 rior process. The other, as it fitted with great exactness into 

 what remained of the socket of the third molar, appeared to 

 have occupied that place in the jaw. Thus it is rendered ex- 

 tremely probable, that all the relics of the Megatherium yet 

 discovered, as far as we know, in North America, have belong- 

 ed to a single individual. 



I shall first endeavour to bring together some of these frag- 

 ments so as to show what has been their original state ; after 

 which they may be compared with the figure and description 

 of the animal of Paraguay, as given by M. Cuvier in the
