3g DESCRIPTION OF AN ENTIRE HEAD 



Though both, skeletons have been inhumed, they do not seem to be fossil^ 

 ized. The first set has a much lighter specific gravity than corresponding re- 

 cent bones would have, and the second set has about the same specific gravity 

 as the latter, or perhaps a somewhat greater, but yet with a freshness of sur- 

 face and of texture which would seem to indicate that either no very long 

 interval could have elapsed since the death of the animal, or that the soil in 

 which they were deposited possessed unusual preservative powers. 



Of the skeleton of the larger animal there are the following pieces: 



A fragment of the pelvis, containing the right acetabulum. 



Inferior end of right scapula. 



Inferior end of left scapula, a small fragment. 



Upper end of right radius and ulna, with olecranon process, the latter de^ 

 tached. 



Lunare — Trapezium — Trapezoides of right carpus. 



Head of a rib. 



Ten fragments of vertebrse, &c., and a number of undetermined fragments, 

 much comminuted. 



The long diameter of the glenoid cavity of the scapula measures nine and a 

 half inches. 



The diameter of the acetabulum is seven and a half inches. 



The lunare is three and three-eighths of an inch in thickness. 



Upon the preceding data, this animal was from a thirteenth to a tenth larger 

 than the Mastodon of the Philadelphia Museum, whose scapula has a glenoid 

 cavity of eight and three-fourths of an inch in its long diameter, and an aceta- 

 bulum of six and three-fourths of an inch in diameter. 



The bones of the second, or smaller animal, are in a state of fine preserva- 

 tion, and consist of 



A complete head. 



Six anterior cervical vertebrae. 



Six vertebrae of thorax and loins, complete, and some fragments of same class 

 of bones. 



Sacrum complete, and seven succeeding caudal bones. 



The left innominatum complete; the right ischium and pubes, with some 

 fragments of right ilium. 



Thirteen ribs of right side. 



Eighteen ribs of left side.
