54 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
the shell was somewhat crushed so that a few of the neurals are 
slightly injured, as well as seme of the peripheral plates above the 
left bridge. No essential part of the structure of the shell is ob¬ 
scured. 
The shell shows no indications of youth. The bones are closely 
apposed, so that it is sometimes difficult to discover the sutures. 
Nevertheless, the animal was a small one. The length from the 
front of the plastron to the rear of the carapace is only ioo mm. 
On account of the great convexity of the plastron it is believed 
that the shell belonged to a female. The following measurements 
have been secured:

The structure of the carapace is identical with that of various 
species of Testudo. The costal plates about the bridges are alter¬ 
nately wide above, with narrow distal ends, and narrow above, 
with wide distal ends. Those costals which are wide above artic¬ 
ulate each with three neurals, the middle one of which is slightly 
smaller than the others. Behind the series of neurals there are 
two suprapygals and a pygal. The last suprapygal has a width 
of 21 mm.; the pygal a width of 27 mm. The disturbed condition 
of the neurals precludes measurements of all of them. The first 
and the fifth have a width of 13 mm. The peripheral bones above 
the bridges have a height, from their lower borders, of 21 mm.; 
while the costals joining them have a height of 32 mm. 
The vertebral scutes are of moderate width, the third being 
21 mm. wide, the fourth, 23 mm.; the fifth 29 mm. 
The supracaudal scute is not divided. The front of the an-
