TESTUDO OCALANA, NEW SPECIES. 
Plate 3, figs. 1-4; Plate 9, figs. 1-3. 
Type-specimen. —Left half of the epiplastron, No. 4299 of the 
Florida Geological Survey. 
Type locality and formation .—Ocala, Florida. Pleistocene. 
Diagnosis. —Epiplastral beak closely resembling that of T. 
crassiscutata. Thickest part of border behind the beak distant from 
free edge less than the thickness. In T. crassiscutata the thickest 
part equal to only one-half its distance from the free edge. 
In a considerable collection of tortoise remains, including more 
than one, probably three or four species, which was presented by 
the Florida Lime Company and made near Ocala, Marion county, 
are some parts which belong apparently to an undescribed form. 
To this is given the name Testudo ocalana. As type of the species 
is taken the left half of the epiplastral beak, No. 4299 (pi. 3, fig. 
1). This resembles closely the corresponding bone of a specimen 
which was found in Hillsboro county and which, after being re¬ 
ferred provisionally to T. crassiscutata, was figured in three posi¬ 
tions (Foss. Turtles N. A., p. 461, figs. 622 a-c). These figures 
are here reproduced (pi. 9, figs. 1-3) and will serve to illustrate 
the Ocala specimen. The latter measures from the midline in 
front to the outer hinder angle 79 mm.; the greatest thickness of 
the epiplastral lip is 34 mm., somewhat less than in the one fig¬ 
ured. The greatest thickness at the end which articulated with 
the hypoplastron is 18 mm. It seems necessary to refer this spec¬ 
imen from Hillsboro county to this species. 
In the collection is a large part of a hyoplastron, No. 4292, 
(pi. 3, fig. 2) which belonged to a slightly larger individual, in¬ 
asmuch as the greatest thickness at the hyo-epiplastral suture is 
22.5 mm. The form of the thickened border in this region is iden¬ 
tical in the two specimens. 
The bone extends to the midline and includes 28 mm. of this 
border behind the entoplastron. From this fact it is determined 
that the front lobe, measuring from where the humeropectoral sul¬ 
cus crosses the border, had a width of 160 mm. The entoplastron 
was 66 mm. wide and was rounded behind. The sulcus mentioned 
passed close behind the entoplastron. The length of the pectoral
