72 The American Geologist. August, 1893 
This skeleton, though probably that of a well-matured indi- 
vidual, does not represent the largest size which the species 
attained. 
Its head is not so large as one already spoken of, in the 
United States museum at Washington. A fragment of the 
right half of a lower jaw found many years since at Memphis, 
Tenn., and described by Dr. J. Wyman, shows a decidedly 
more massive series of grinders. 
VII. Fragments from the Same and Other Localities. 
The nearly complete skeleton thus far considered we will 
call No. 1. 
No. 2. The distal end of a right lower incisor. This frag- 
ment is near four inches in length and has the crown badly 
hacked, scarred and striated by its antagonist. The enamel 
is flaked oft' anteriorly for near two inches backward from the 
cutting edge, showing the glossy grooved surface of the den- 
tine. This fragment indicates an animal much smaller than 
No. 1, and was picked up quite remote from it. 
No. 3. Five scraps of enamel with adhering dentine, size - 
from half-inch square to one by one and a half inches, found 
near locality of No. 1. These clearly indicate, by the coarse- 
ness of the striae and the width of one of the pieces, a very 
large upper incisor. 
No. 4. A right humerus, well-preserved, except that the 
proximal epiphysis is wanting. This indicates a creature for 
size about equal to No. 1. 
No. 5. The distal f of another right humerus indicating 
an animal larger than No. 1. 
No. 6. A left calcaneum, perfectly preserved and having a 
clean, fresh look. This also indicates a larger specimen than 
No. 1 and may or may not belong with No. 5. 
No. 7. The proximal extremities of radius and ulna, each 
about two inches long, showing articular surfaces perfectly, 
and indicating a full sized animal. 
No. 8. The proximal ^ of a right fourth metatarsal. 
No. 9. The proximal end, three inches long of the right 
third metatarsal. This bone is larger than its homologue in 
No. 1. 
No. 10. A fragment of an atlas showing perfectly the ar- 
ticular surfaces on one side.
