52 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
At present, it appears that parts of the carapace, not found with 
the rear portions of the plastron, belonging to T. crassiscutata, T. 
seilardsi and T. hayi, can hardly be distinguished, the one species 
from the other. 
A comparison of text-figure 6 with that of a, large land tor¬ 
toise figTired by Dr. Sellards, but without a systematic name 
(Seventh Ann. Rep. Fla. Geol. Surv. 1915, p. 70),* shows at once 
that the animals represented belonged to quite distinct species. In 
the species figured by Sellards only the second neural bone had 
taken on the octagonal form. Indeed, the neurals in general had 
attained a stage of differentiation representing that of the Oligo- 
cene genus Stylemys. The fourth neural is hexagonal; whereas, 
in T. seilardsi it is octagonal. The' fifth neural has quite different 
forms in the two species. 
TESTUDO LUCIAE, NEW SPECIES. 
Plate 9, fig. 5. 
Type-specimen. —Part of the right hypoplastral bone, No. 1807 
of the Florida Geological Survey. 
Type-locality and formation. —Vero, St. Lucie county, Florida. 
Pleistocene. 
Diagnosis. —A species perhaps as large as T. crassiscutata, but 
differing in having a thinner wall along the border of the base od 
the hinder lobe. 
Among the materials in the Florida paleontological collection 
is a part of a very large species of Testudo which appears not to 
have been hitherto recognized. This fragment has the number 
1807 and is recorded as having been obtained from the canal of 
the Indian River Farms Company, east od the Florida East Coast 
Railway, near the Indian river, at Vera, St. Lucie county. There 
can hardly be any doubt that the animal lived during the Pleisto¬ 
cene. 
The part present and forming the type of the species belongs to 
the rig'ht side and hinder part of the hypoplastron. It is therefore 
a part of the base of the hinder lobe of the plastron. It extends 
backward nearly, but not quite, to the suture with the xiphiplas- 
tron. The animal was about the size of T. crassiscutata Leidy. It 
appears, however, to differ from that species sufficiently. As in 
* Subsequently described as Testudo liayi. American Journal of Science, 
Vol. xlii, Sept., 1916.
