class="bold">Gopherus sp. No. 5935 is from the Pleistocene of Harper County, Kansas, and No. 7677 is from the early Pleistocene of Beaver County, Oklahoma. Each is composed of costals and neurals which may be referred to this genus. Their size indicates an animal considerably larger than any on record, and probably these specimens represent a new species.

Chelydra sp. No. 6821 is the anterior part of a plastron from the Edson Quarry, Sherman County, Kansas. The age is middle Pliocene. This fragment has been listed three times in print, once merely as Chelonia (having reference to the order) (Adams and Martin, 1931), and twice by Hibbard (1934 and 1939) as Chelonia sp. Hibbard's listing was obviously a lapsus calami for Chelydra since he placed the genus in the family Chelydridae.

No. 6479 is part of a costal and marginals from Meade County, Kansas. This specimen was associated with Aenocyon dirus, and is Pleistocene in age.

Amyda sp. No. 6800 is part of a costal collected in Seward County, Kansas. It is possibly of early Pleistocene age. No. 7568 is part of a carapace from Meade County, Kansas, probably of the same age.
