VERTEBRATA AT VERO.

33 per cent. The length of the zygapophysial surfaces on the 
front of the sacrum is nearly twice as great as in the buck men¬ 
tioned. 
Found at the same spot is the practically complete left innomi¬ 
nate bone which belonged with the sacrum. The one of the right 
side is present, but lacks the part behind the acetabulum. Both 
bones make accurate contact with the sacrum. The presence of all 
the bones of this pelvis is of interest because it indicates that they 
had not been washed in from some other place after a previous 
burial. In a small collection made for the writer by Mr. Isaac M. 
Weills there is a part of the first sacral vertebra, which is recorded 
as having been found 8 inches below the upper surface of stratum 
No. 2. The peculiar articulatory surface on the upper face of the 
prezygapophysis is somewhat more strongly developed than in the 
sacrum described above. 
From No. 3 there are present an atlas (No. 7591), an axis 
(No. 7039), a sixth cervical (No. 7591), an eleventh dorsal (No. 
7591), and the right ramus of a lower jaw (No. 7039) containing 
well-worn teeth. These were found near one another on the north 
side of the canal, 100 feet north of the railroad bridge. At least 
the atlas and the axis belonged to one individual. They point to a 
deer larger than 0 . sellardsiae; but common parts for comparison 
are wanting. The atlas, axis, and sixth cervical do not show any 
characters that separate them with certainty from O. virginianus; 
and they indicate a deer fully as large as this species. For the 
present they may be referred to 0 . osceola. The body of the 
eleventh dorsal is 3 mm. longer than that of the buck of the Virgin¬ 
ian deer mentioned. The postzygapophyses have the same modifica¬ 
tion as has been described in the case of the lumbars which are 
referred to 0 . sellardsiae. 
With difficulty Doctor Sellards secured, through Isaac M. 
Weills, most of the vertebrae and the pelvis of the existing Florida 
deer, 0. osceola, for comparison with the fossil deer and with 
0. virginianus. 0 . osceola is certainly distinct from O. sellardsiae. 
Unfortunately the skeleton of O. osceola is that of a young female 
and one cannot be sure that the many differences found between it 
and such skeletons of 0. virginianus as are at hand are not due to 
immaturity or to sex. 
In the, collection sent by Dr. Sellards are the proximal ends 
of two scapulae from No. 3. They have the catalogue numbers
