quarry of Messrs. Hounshell, Pierce & Co., situated a little more than 

 1 mile north of Rogersville. The fossils are all of Pleistocene age 

 and they were doubtless buried in crevices in the marble. The matrix 

 that is attached to some of the bones is the red earth characteristic 

 of cave deposits. Only two species are recognized, Equus leidyi and 

 Platygonus setiger, a species regarded as new. 



Family EQUIDAE. 



EQUUS LEIDYI Hay. 



A single tooth of a horse accompanies the collection — an upper 

 right first or second true molar. Its antero-posterior diameter is 26 

 mm. its width 24 mm. It has the catalogue number 520 of the United 

 States National Museum. 



Family TAYASSUIDAE. 



PLATYGONUS SETIGER, new species. 



Plate 3, figs. 21-23. 



Type specimen. — A lower right canine, with most of the crown 

 missing. Cat. No. 519, U.S.N.M. 



Type locality. — Hawkins County, Tennessee. 



Type formation. — Pleistocene. 



Diagnosis. — A large species. Section of crown at base a nearly 

 equilateral triangle. The outer face convex, with broad low ridges 

 on the outer face of the crown. Inner face with a groove along the 

 middle of the width and with a ridge in front and behind the groove. 

 Eoot with longitudinal grooves and ridges on each lateral face; the 

 hinder face occupied by one broad deep groove. 



There is in the collection from Rogersville a part of a large lower 

 left canine (Cat. No. 519) of a peccary, which is here named Platy- 

 gonus setiger (pi. 3, figs. 21-23). Nearly the whole of the crown is 

 missing, but the freshness of the break indicates that the collector 

 did not preserve the missing part. Also a little of the extremity of 

 the root is broken away. The length of the portion of the tooth pre- 

 served, measured along the anterior border, is 114 mm. Evidently 

 the tooth belonged to a fully grown, but not aged, individual. The 

 curvature is about the same as in Platygonus compressus. The sec- 

 tion of the crown at the breal^ is triangular. The inner face is flat 

 and 14 mm. wide; the hinder face, slightly concave (due partly to 

 wear against the upper tooth) and 15 mm. wide; the outer face, con- 

 vex and 18.5 mm. wide. The front of the tooth presented a subacute 

 edge. The hinder face of the root has a broad channel throughout 

 its length. The inner face is flat, rounding off behind into the hinder 

 face. All of the faces are grooved and ridged. The writer has
