The area occupied by the anal scute is rough and it occupies a slightlv different level from the rest of the bone. As stated by Cope, this species may belong to the genus Gopherus (Xerobates), but this can not be determined before the skull has been found. Testudo hexagonata Cope. Figs. 625, 626.

The present species is based on a specimen now in the University of Texas, at Austin, Texas, where the writer has been permitted to study it. The specimen was found by Prof. W. F. Cummins, of the Texas Geological Survey, in the Equus beds, on Rock Creek, a stream emptying into Tule Canyon, in Briscoe County, Texas. The carapace of this shell is considerably crusht and fractured, and somewhat weathered. Various parts of the free border are missing. It is therefore difficult to secure the details of the structure, and this portion of the shell was not described by Cope. A figure is here presented (fig. 626) which gives as well as could be determined the structure of the carapace. 62;.
