62 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
In the collection made by Doctor Sellards at Vero, Florida, are 
several portions of the carapace of a bocx-tortoise which appears to 
differ from any of the described species, but which does resemble 
considerably female specimens of T. major, a common species of 
Florida. Two of the specimens from Vero furnish nearly com¬ 
plete carapaces. These have the numbers 7079 and 7080. In both, 
all the bones are thoroughly consolidated, so that no sutures are to 
be seen. I11 the one numbered 7079 the furrows separating the 
dorsal dermal scutes are so indistinct that these boundaries cannot 
in all cases be made out. In many places, too, the costal scutes 
appear to have been broken up into numerous minute patches. On 
this account the carapace numbered 7080 is taken as the especial 
type of the species (pi. 6, figs. 1, 2). 
In order to facilitate comparisons between this species and its 
existing relative, possibly descendant, T. major, the following table 
of measurements is provided. Two specimens of T. major, a fe¬ 
male and a male are measured, so that some of the variations which 
this species undergoes may be observed.
