Ari'ozu-Head Found in Kansas — Jl^illisfon. 313 
AN ARROW-HEAD FOUND WITH BONES OF 
BISON OCCIDENTALIS LUCAS, IN 
WESTERN KANSAS. 
By S. W. WiLLlSTON, Chicago. 
In the summer of 1895, Mr. T. Overton and Mr. H. T. 
Martin, assistants in the paleontological department of the 
University of Kansas, under my direction, while engaged in 
the collection of vertibrate fossils in western Kansas, had their 
attention directed to a number of mammal bones protruding 
from a bank of a small tributary of the Smoky Hill river in 
Logan county. From their description, I at the time recog- 
nized an extinct form and urged them to collect all the bones 
with care. 
Both men had had much experience in the collection and 
preparation of fossil vertebrates, and Mr. Martin especially 
has a wide reputation for his (Skill and trustworthiness in such 
matters. The bones were at first identified by me as pertain- 
ing to the extinct species Bison antiquus Leidy, and were so 
described by Mr. A. T. Stewart of my laboratory. Later, 
however, Mr. Lucas of the National Museum, after an exhaus- 
tive study of the known species of fossil bisons of America, 
recognized the species as new, and gave to it the name Bison 
occidentalism known otherwise only from a fragmentary skull 
collected in Alaska ond now preserved in the National Muse- 
um. 
The arrow-heaad was first discovered by Mr. Martin in re- 
moving the bones of one of the skeletons, but it was almost 
immediately seen by Mr. Overton while lying in its original 
position, as also by a gentleman who was watching the exhu- 
mation of the bones. While the evidence thus rests almost ex- 
clusively upon the testimony of Messrs. Martin and Overton, 
I have not the slightest doubt of its reliability. I know from 
an intimate aquaintance, that Mr. Martin is reliable, and I am 
confident that the testimony of the two would be accepted as 
conclusive in any court of justice. 
Mr. Martin's description, given at my request, is as fol- 
lows : 
"The exact locality of the l)one-bed where the arrow-head 
was found associated with the bison bones is about one- 
half mile north of the Smoky 1 Till river on Twelve Mile creek,
