No. 2328. PLEISTOCENE VERTEBRATES IN UNITED STATES— HAY. 99 



ville, a few miles north of Cumberland, Maryland. In the collection 

 from Cavetown there is a fragment of the left ramus of a mandible 

 which contains the three molars (Cat. No. 9167). Inasmuch as these 

 are less worn than the teeth of the type, it is thought well to figure 

 them (pi. 4, fig. 4). Measurements are here presented of these 

 teeth and the corresponding ones of the type of the species.

As will be observed there is close correspondence in the measure- 

 ments. There appears to be equally close agreement in the structure 

 of the teeth. 



Figure 5 of the plate 4 represents a lower left third premolar 

 (Cat No. 9168), wholly unworn, whose length is 128 mm. and whose 

 width is 11 mm. Figure 6 gives a view of a lower left first molar 

 (Cat. No. 9169), unworn. It is 15.5 mm. long and 13 mm. wide. A 

 lower left second unworn molar (Cat. No. 9170) is shown by figure 7. 

 Its length is 18 mm. ; its width 14.2 mm. 



Of upper teeth there are those identified as second, third, and 

 fourth premolars (pi. i, fig. 8) of one individual (Cat. No. 9171). 

 The following comparative measurements are given of the premolars 

 of the figure just cited :
