nothing representing the median portion of the carapace; so that 
it is not known whether or not there was a median keel. 
This species differs from T. formosa in various respects. It 
appears to have attained a greater size and to have had a thicker 
and heavier shell. It appears to have been narrower in proportion 
to the length. The border of the carapace at the lateral hinge 
line, as stated above, is turned inward at nearly a right angle with 
the part of the peripherals above the lateral keel. In T. formosa 
the border is directed downward and only a little inward; so that 
the lateral keel is placed high above the lateral hinge. 
Terrapene canaliculate (Hay, Foss. Turtles N. A., p. 363, figs. 
463-465) more closely resembles T. antipex than T. formosa; but 
the lateral keel is much more conspicuous, the free borders of the 
peripherals are more strongly recurved and the shell is still thicker 
and heavier. It is to be noted here that the peripheral illustrated 
by figure 463 of the work cited belongs to the left side, instead of 
the right. 
It is evident that none of the above mentioned box-tortoises 
belong to T. putnami (Foss. Turtles N. A., p. 361, figs. 459, 460). 
This was a still larger animal than T. antipex, having had a plas¬ 
tron 146 mm. wide. The hypoplastron was, proportionately, much 
thicker than that of the species last mentioned. It is possible that 
the fragment of the carapace referred (as just cited, fig. 461) pro¬ 
visionally to T. putnami belongs really to T. antipex; but the rear 
of the carapace (fig. 462) is very different from the one above de¬ 
scribed from Vero, No. 5480; for in the latter the pygal or twelfth 
pair of marginal scutes rise to the upper border of the pygal bone; 
in that of figure 462, little more than to half the height of that 
bone.
