270 Fossil bones in Georgia. 



ness and height ; and from the appearance of the vertical 

 ridge at the lower extremity, could not have admitted of as 

 much motion at the articulation with the first phalanx. There 

 is also in this ridge a pretty deep notch, which is not found in 

 the Megalonyx. 



This comparison serves also to throw light upon another 

 question. M. Cuvier conjectures, that in setting up the 

 skeleton of Madrid, the fore feet have been transposed, and 

 that the right is on the left side, and vice versa. But this 

 can hardly be the case, for the bone we have been examining, 

 which the comparison with the Megalonyx shows to have 

 belonged to the left side, agrees also with that which is so 

 placed in Pander's figure of the Madrid skeleton, pi. iv. f. 28. 

 If, however, this error has been committed, there must also 

 be an error in referring the bone fig. 4. of the plate of the 

 Megalonyx, in the " Ossemens Fossiles," to the left side. 



I am informed that a gentleman of Savannah has in his 

 possession, from the same Island, an entire lower maxillary 

 bone, which is said to agree in all respects, with the descrip- 

 tion of the Megatherium. This must have belonged to a dif- 

 ferent individual from that whose remains are now in the 

 Cabinet of the Lyceum ; so that there have been discovered 

 in the United States, parts of at least two different skeletons 

 of this animal.
