Vespertilio, sp. 



Numerous bones of bats occur in the breccia. A portion of maxillary 

 with teeth was preserved, but fractured in the attempt to expose it. 



Tapirus hatsii, Leidy. 



Several inferior maxillary molars. They all have a rather greater an- 

 teroposterior diameter than those of the existing Central and South. 

 American species. 



Equus ? COMPLICATUS, Leidy. E. americaniis, Leidy. 



Upper and lower milk and permanent molars. 



DicoTYLES NASUTUS, Leidy. Proceed. Acad. Nat. Sci., Philada., 1868, 



Several molar and canine teeth. 



DicoTYLES COMPRESSTJS, Lecoiite. Platygonus compressus, Lee, etc. 

 Amer. Journ. Sci., 1848, 102. Dicotyles, Leidy, Trans. Am. Soc, XI, p. 

 97, also X, 324. 



Not found by me in Virginia; abundant at Galena and elsewhere. 



Cariacus viRGiKiAKTJS, Orcty. Cermts, Bodd. 



Molars and other fragments of this species are perhaps the most abun- 

 dant in the breccia. One posterior portion of ramus mandibuli with 

 tooth in situ is in the collection. 



B6s ? ANTiQUTJS. Bison, Leidy. 



Molar teeth. 



Ursus amplideks, Leidy. Proceed. Acad. Nat. Sci., 1853. 



A single posterior lower molar of this species, identical with that de- 

 scribed by Leidy from a ravine near Natchez. 



Ursus americaktjs, Linn. Leidy, Journ. Ac. Nat. Sci., Phila., Ill, 

 169. 



From various caves; not found by me in Virginia. 



Procyon prisctjs, Leconte. Leidy, Journ. Acad. Nat. Sci., Ill, 169. 



Perhaps the same as the next; From Galena. 



Procyon lotor, Linn. 



A posterior inferior molar^ not distinguishable in any point from a 

 specimen from a New Jersey peat swamp, both identical with the common 

 raccoon i 



MiXOPHAGTJS SPELAETTS. 



This animal is represented by a molar tooth, which though somewhat 

 imperfect is so characteristic as to require notice. It appears to have 

 been derived from the lower jaw from the behind position of the sectorial. 

 It resembles the tubercular sectorial of the bear, but is even less acutely 

 tubercnlate, and is a little smaller than the same tooth in the raccoon. 

 The surface of the crown exhibits concavities between small pointed 

 cusps. The outer margin is a low ridge of four cusps. In front it rises 

 into a more elevated cusp. Here also the tooth is wider, and presents a 

 wider plane of the crown. Part of the inner margin is here broken away, 

 but a little behind its middle a stronger cusp rises, one-third of the width
