PLEISTOCENE VERTEBRATES FROM CUMBERLAND CAVE 53 



:Stock (1932, figs. 74, 92, 103, 106, 126, 130) shows the scapholunar, as- 

 tragalus, calcaneum, and third metatarsal to be markedly similar to the 

 corresponding elements in the California material but nearly one-third 

 smaller. However, their dimensions are only shghtly less than those 

 given for a small individual in each case. The second metacarpal 

 and fifth metatarsal in addition to being smaller are relatively slen- 

 derer than in the Rancho La Brea form. 



A third metacarpal in the Port Kennedy collection, referred by 

 Cope (1899, pp. 247-249) to F. inexpedata, compares favorably in 

 length with the corresponding bone of a large puma but belongs to a 

 foot much smaller than that indicated by the second metacarpal 

 from Cumberland Cave. A fourth metacarpal from Conard Fissure 

 bearing the number A.M.N.H. 11787, as does the type of F. longicrus, 

 is as robust as in F. tigris but markedly shorter, resembUng that of 

 a, saber-tooth form.

Order RODENTIA 

 Family SCIURIDAE 



MARMOTA MONAX (Linnaeus) 



In the collection from the Cumberland Cave deposit there are a 

 number of specimens referable to a single species of woodchuck. 

 They include seven nearly complete skulls, several lower jaws, and 

 other bones of the skeleton. The better-preserved carry the National 

 Museum catalog numbers 7997, 8127, 8157, 8158, and 8183. 



The cheek teeth in the cave specimens average somewhat less in 

 size and the skulls average somewhat larger compared with a large 

 series of the living species, but in these and all other differences noted 

 they fall well within the range of individual variation of Marmota 

 monax. For this reason they are referred to the li\'ing species.
