20.5 mm. In the case of the first molar of Cer^us canadensis the 

 length at the base of the crown is 21 mm. ; the width, 26 mm. The 

 fossil tooth differs from the cheek teeth of Cei^iLS canadensis and 

 Odocoileus virginianus in the almost complete absence of the median 

 ribs on the outer faces of the anterior and posterior lobes. In both 

 of the species named these ribs, especially the anterior one, are very 

 prominent. 



CERVUS CANADENSIS Erxlebcn. 



In the collection fi'om Whitesburg there is a fragment of an upper 

 left molar which appears to belong to this species (Cat. No. 8555). 

 This fragment consists of the outer wall of the paracone. The ridge 

 which descends on the middle of the outer face of this part of the 

 tooth in this species is well developed. Another fragment of a lower 

 molar (Cat. No. 8556), belonging possibly to the same species, is not 

 so satisfactorily determined. 



Family ELEPHANTIDAE. 



ELEPHAS PRIMIGENIUS Blamcnbach. 



Plate 3, fig. IG. 

 In the collection from Whitesburg there is found the rear of a 

 second milk molar, probably a lower one (pi. 3, fig. 16). There 

 are present only one ridge plate and the talon. On geogi-aphical 

 grounds one would conclude that the tooth belonged to Elephas 

 colnmbi. However, the plate is remarkably small. From side to side 

 the width is only 26 mm. ; the height also, close to 26 mm. Its small 

 size indicates a tooth of the southern form of E. primigenius. Inas- 

 much as the latter species has been recognized as far south as Beau- 

 fort, North Carolina, and in Texas, it might, perhaps during a 

 Pleistocene glacial stage, have peopled the mountain regions of 

 eastern Tennessee. The specimen has the catalogue number 8957. 



Family SCIURIDAE. 



SCIURUS HUDSONICUS (Erxleben). 



The writer has found a single upper right incisor which he refers 

 to this squirrel. It is very slightly smaller than in recent specimens 

 that have been examined, but further search would probably bring 

 to light recent teeth as small. The catalogue number is 8958. 



SCIURUS CAROLINENSIS Gmclin. 



This species appears to be represented by an upper left (Cat. No. 

 8959) and a lower right (Cat. No. 8960) incisor. AVliile resembling 

 closely the teeth of recent specimens these fossil teeth are thinner. 

 However, a specimen of /S. carolinensis extimus, from Osceola County, 

 Florida, No. 111394 of the United States National Museum, appears
