Evidently the cave is no longer in existence, having probably been 

 eroded away, while its floor was in some way protected from erosion. 

 The following species have been determined in the collection. Those 

 marked with a dagger are extinct. 



\Testudo mimda^ new species. ^S'. caroUnensis. 



\Equus l-eidyi. Tamias str'mtus. 



\Equus littoralis. Marmota monax. 



\Tapirus tennesseae, new species. Castor canadensis. 



]Mylohyus nasutus. Neotoma pennsylvanica. 



Odocoileus virginianus. Microtus pennsylvanicus. 



\Sangamona fugitiva., new genus Lepus arnerlcanus. 



and species. Ursus floridanus. 



Cervics canadensis. Procyon lotor. 



\Elephas priTtiigenius. \Aenocyon ayersif 



JSciwus hudsonicus. 



Twenty species are determined, of which eight are extinct. Pos- 

 sibly materials that are referred to existing species would, if better 

 represented, prove to belong to extinct forms; but they would, at 

 least, be closely related to those recognized. 



Family TESTUDINIDAE. 



TESTUDO MUNDA, new species. 



Plate 3, figs. 1-8. 



Type specimen. — Fragments of carapace and plastron. Cat. No. 

 8944, U.S.N.M. 



Type locality. — Whitesburg, Hamblen County, Tennessee. 



Type formation. — Pleistocene. 



Diagnosis. — A species rather small for the genus. Seventh pe- 

 ripheral with border thickened and recurved ; the ninth with border 

 slightly recurved; the marginal scutes not extending to its upper 

 border ; plastron thick at center of hinder lobe. 



Among the materials from Whitesburg are fragments of both the 

 carapace and the plastron of a tortoise which appears to have be- 

 longed to the genus Tcstudo. The principal pieces are illustrated on 

 plate 3. The elements present are part of the left second peripheral ; 

 the right first rib plate ; the right seventh peripheral ; the right ninth 

 peripheral ; a fragment of a rib, probably the seventh ; a piece of the 

 left hyoplastral bone; a part of both hypoplastrals, coming to the 

 midline ; and a piece of each of the xiphiplastrals, meeting at the mid- 

 line. In the United States National Museum these bones have the 

 catalogue number 8944. These bones show that the animal had a 

 rather thick and heavy shell. The length of the carapace is esti- 

 mated to have been not far from 135 mm.
