recent species. In the fossil the anterior articulating surfaces cover 

 the whole of the fossa for the reception of the occipital condyles, but 

 do not in two recent bones, with which they have been compared.

7. Metacarpal bone of gigantic size when compared with the 

 same part in the existing species.

8. Second phalanx; length 3.45 inches in the fossil, 2.20 inches in 

 the recent species. 



The height of the existing lama at the shoulders is about three feet. 

 If the proportions of the fossil were the same as in the recent species, 

 then the height of the former at the shoulders as deduced from the 

 size of the metacarpal bone was about five feet. 



9. A fragment of the upper end of the femur of a Tapir. The 

 head and neck of the bone are gone. 



10. Two molar teeth of the upper jaw of a Deer, of about the size 

 of those of the Cervus virginianus. 



11. Last molar from the lower jaw of a Deer much larger than the 

 preceding. 



12. The left Humerus of a Deer, the lower end of which is broken 

 off. This belonged to an animal somewhat smaller than the Moose. 



13. A fragment of the pelvis comprising portions of the left acet- 

 abulum, of the ramus of the pubes and of the ascending part of the 

 ilium. It resembles the corresponding part from the horse, though the 

 indentation for the attachment of the rectus muscle is deeper. Uncer- 

 tain as to its specific character. 



14. A fragment of the pelvis comprising the same parts as the pre- 

 ceding, but as large as those of the common horse. 15. Upper end 

 of the tibia of a large Ruminant. 16. Another fragment of the same 

 as the preceding. 17. Astragalus of a Ruminant. 18. Lower end 

 of the tibia of a Ruminant. 19. Caudal vertebrae of a Megatheroid 

 animal. 20. Os calcis ; 21. Fragment of the ilium; 22. Occipital crest; 

 23. Undetermined bones ; and 24. Lumbar vertebrae ; not determined.
