teeth of the Mylocheilus type, more or less cylindrical, with rounded 

 grinding surfaces. What special use a minnow had for such teeth 

 as those of Alisodon it is hard to determine.

TERRAPENE WHITNEYI Hay. 



This species appears to be represented by a fragment of the upper 

 shell, presenting the region occupied by a part of the first costal 

 scute, and the first, second, third, and a part of the fourth, marginal 

 scute areas; also by an anterior lobe of the plastron, lacking a left 

 hinder corner ; and a small part of another anterior lobe. These parts 

 have the catalogue number 9220. When these remains are compared 

 with the fine type of the species, now in the United States National 

 Museum, only appar- 

 ently unimportant 

 differences are ob- 

 served. 



l-ERRAPENE BULVERDA, 

 new species. 



Plate 10, fig. 1. 



In the collection 

 are several fragments 



of one or more species ^^^^ 4.-Tr««APENE eulvekda. reae op cakapace x i. 

 of box tortoise that 



are not referable with satisfaction to any of the described species. 

 That these fragments belong to one species is doubtful ; they certainly 

 belong to more than one individual. It is thought better to give a 

 specific name to the most characteristic piece and to refer the others 

 to it provisionally. 



The fragment that is made the type of T. hulverda is a part of the 

 hinder half of the carapace, including j)arts or wholes of the fourth 

 and fifth vertebral scutes, the fourth right and left costal scutes, the 

 left third costal scute, and the eighth, ninth, tenth, and eleventh left 

 marginal scutes. 



This box tortoise was a large one. The width at the rear of the 

 lateral hinge lines was not far from 140 mm. The bones are all 

 solidly grown together. To illustrate the form of the various scutes 

 a line drawing (test fig. 4) is provided, which represents them as 

 spread out flat. It will be seen that the fourth vertebral scute is urn- 

 shaped and narrow behind. The width at the widest part preserved 

 is 42 mm. Its length was about 35 mm. The fifth vertebral scute 

 was unusually wide, about 48 mm. The ninth marginal is 23 mm. 

 long and 20 mm. high.
