48 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
The outer face of the bone is nearly flat, as is too that of the pre¬ 
served part of the eighth peripheral. On the inner face of the 
seventh peripheral is seen the ridge against which rose the hypo- 
plastral buttress. This buttress appears to have been ankylosed 
to the peripheral. 
The right seventh peripheral (pi. 3, fig. 7) belonged to a 
younger individual. On the plate its lower border is directed up¬ 
ward and the inner face is shown. A fragment of the hypoplastral 
buttress remains attached. The outer surface is nearly flat. The 
lower border is hardly notched. What appears to be a ninth, pos¬ 
sibly an eighth, right peripheral is represented as showing its front 
border (pi. 3, fig. 8). The individual was of about the same 
size as that of figure 7. The outer surface is convex from front 
to rear, but plane from above downward. There is a quite deep 
notch in the free border. 
TESTUDO DISTANS, NEW SPECIES. 
Plate 3, fig. 9.- 
Type-specimen . — An entoplastron, No. 4289, in the collection 
of the Florida Geological Survey. 
Type-locality and formation. —Ocala, Florida. Pleistocene. 
Diagnosis . — Rear of entoplastron largely occupied by the pec¬ 
toral scutes. 
In the collection made at Ocala and presented by the Florida 
Lime Company is a large entoplastron which is different from any 
known to the writer. A description of it may eventually lead to 
the discovery of other parts of the species. It is represented by 
figure 9 of plate 3. The remarkable feature of the bone is the 
fact that the pectoral scutes extended forward on its area; where¬ 
as in nearly all other species of the genus these scutes have their 
front border just behind it. 
The length of the bone along the midline is 128 mm.; the 
greatest width, 145 mm. The thickness near the midline and 80 
mm. behind the front is 15 mm. As will be observed, the gular 
scutes extended backward on the entoplastron about 20 mm. The 
length of the humerals on the entoplastron is about 80 mm. but 
the left one is the shorter. The humero-pectoral sulcus entered 
the area of the bone nearest its widest part and swept forward 
and inward, then backward and inward to the midline. 
This bone cannot belong to T. crassiscntata; because the ento-
