on a card with the name "Bison Americanus DeKay, Luzerne Co., 

 Pa." Accompanying them is a small card in Dr. Leidy's writing, 

 which reads: "With the fossil teeth from Luzerne Co., but appar- 

 ently more recent. Bison Americanus." I have compared these with 

 specimens of the recent animal and find them to be specifically iden- 

 tical. 



Waiving the question of the real status of the tooth figured by 

 Leidy from this locality, we may safely rest the eastward extension 

 of the habitat of Bison bison from Lewisburg sixty miles along the 

 north branch of the Susquehanna on the two lower molars. 



In the report of the Pennsylvania Geological Survey for 1887, 

 Dr. Leidy, in a paper on limestone cave fossils of the State, makes 

 the following statement in relation to certain bones found in Hart- 

 man's cave, Monroe County: — "With the remains of existing ani- 

 mals are those of a few species which no longer live in Pennsylvania 

 * -l- * represented by a few jaw fragments and teeth of the wood- 

 land reindeer, Rangifer caribou, and a lower jaw fragment with the 

 last molar tooth of the bison, B. Americanus." This jaw fragment 

 and its accompanying tooth are in the collection of the Academy. 

 They belonged to a full grown animal in its early prime. The crown 

 of the tooth has apparently been charred and crumbled by tire in 

 the same manner as other bones from this cave which surrounded 

 and lay within the site of an ancient fire place in the superficial 

 layers of the cave floor. The mandible, which is about, four inches 

 long and two inches wide and contains the alveoli of the three true 

 molars, is uuburnt and is apparently of the same recent age as the 

 remains of the fox, wolf and deer associated therewith. 1 have no 

 hesitation in considering Dr. Leidy's identification correct, and from 

 the character of the ethnological remains found in the same cave 

 and the appearance of the bone itself, would judge it had formed 

 part of the feast of a Delaware Indian in comparatively recent times. 

 This record extends the wanderings of Bison bison to the Delaware 

 Valhy. 



There is in the Academy's collection the basal portion of a horn- 

 core of a fossil bison taken from a closed limestone crevice in Dur- 

 ham cave on the bank of the Delaware near Riegelsville, Pucks 

 County. This specimen is of evident antiquity and apparently be- 

 longs to the leftside of the skull, having attached to the core a frag- 

 ment of the frontal bone, two and one-half inches square. The core
