iIEASUREMENTS OF LOWER MOLARS IN MILLIMETERS. 



So far as shoAvn by the first and second molars, the Cavetown 

 specimen is quite distinct from P. cumherlandensis. While allow- 

 ing something for individual variation, which is met with constantly 

 in these peccaries, it appears better to refer the teeth from Cavetown 

 to P. vetus. A fragment of the crown (Cat. No. 9190) of a lower 

 tusk also is referred provisionally to this species. This fragment is 

 only 20 mm. long. The section (pi. 4, fig. 19) forms a nearly isoceles 

 triangle whose height is 14.5 mm. and whose base (the rear face of the 

 tooth) is 11.5 mm. It resembles considerably the lower canine of 

 the species named by Gidley M. intemiedius, and possibly it belongs 

 there. It seems to be too sharp on its front border and too thin to 

 belong to M. cumherlandensis. 



PLATYGONUS CUMHERLANDENSIS Gidley. 



The presence of this species in the fissure at Cavetown appears to 

 be indicated by a part of the root of a lower left canine (Cat. No. 

 9191). The fragment is 30 mm. long. At the lower end the pulp 

 cavity is large ; but above it is much reduced. It formed a part of 

 a very large tooth. The fore-and-aft diameter is IT mm. ; the side- 

 to-side diameter, 9 mm. The front border is rounded; the hinder, 

 occupied by a conspicuous and deep groove. There is also on each 

 lateral face a well-defined groove. A section of the tooth forms, 

 therefore, a trefoil. The root is furnished with rather fine ridges 

 and grooves. It appears best to refer this tooth to P. cumherland- 

 ensis. 



Family CERVIDAE. 



SANGAMONA FUGITIVA Hay. 



In the collection from Cavetown there are some remains of a deer 

 which are referred to the species described above f rom WHiitesburg, 

 Hamblen County, Tennessee, as Sangamona fugitiva. These re- 

 mains consist of a lower right first incisor; a lower left first, or 

 possibly second, true molar ; the distal end of the left radius ; a right 

 scaphoid, a part of the right innominate bone surrounding the 

 acetabulum ; a left external malleolar bone, the proximal half of an
