The specimen furnishes the carapace and plastron, both somewhat 

 damaged, and the nearly complete skull. On account of the close 

 application of the lower jaw to the skull, the character of the tritur-

 however, no reason for supposing that the species is not a Testudo.

The length of the skull (Figs. 1-3) from the snout to the occip- 

 ital condyle, was very close to 53 mm. The width across the auditory 

 chambers is 40 mm. The width of the interorbital space is 12 mm. 

 The orbits are nearly circular, with a diameter of 15 mm.

The shell (Figs. 4, 5) is damaged so that little can be determined 

 regarding the neurals and the vertebral scutes. The general form of 

 the shell is well preserved. The carapace is 320 mm. long and 280 

 mm. wide. 



The plastron has a prominent epiplastral lip. This projects 30 mm. 

 in front of the gulo-humeral sulci. It greatest thickness is 26 mm. 



Testudo arenivaga, sp. nov. 



This species is based on fragments of a large turtle which has the 

 catalogue number 1509 of the Carnegie Museum. The remains were
