Bos in the Quaternary of Arizona. — Blake. 69 
Science, which was found in a creek emptying into the Ohio 
river. Dr. Harlan* gave it the name of Bos latifrons. A cast 
of the specimen was sent to Cuvier in France. Notwithstand- 
ing its size and locality Cuvier considered it to represent Bos 
priscus. Leidy in July, 1852, asked the attention of the mem- 
bers of the Academy to the fossil and Cuvier's determination 
of it, stating that it belongs to a species of bison and is with 
very little doubt distinct from the Bison priscus and should be 
called Bos latifrons. Again, in his memoir he states that Dr. 
Harlan was quite justifiable in proposing the name Bos lati- 
frons for this animal. Leidy, however, in the same memoir 
■gives a description and figure of the fossil with dimensions un- 
der the name of Bison latifrons. 
The horn-core of this specimen was no less than 20^ 
inches in circumference at the base and \'j\ inches at ten 
inches from the base. Only about one-half of the length of 
this horn-core was preserved. Judging from the figure given, 
one-fourth size, the core more nearly resembles the horn-core 
from Arizona than any other of which descriptions have been 
found, but these specimens do not appear to me to bear any 
resemblance to the horn-cores of our lately existing bufTalo. 
At the same meeting of the Philadelphia Academy noted 
Dr. Leidy exhibited a fragment of another skull and horn 
which must have belonged to a smaller animal. "The horn- 
core is relatively more conoidal and curved than in Bison 
latifrons." It was from Big Bone Lick, Ky., and probably in- 
dicates a distinct species for which the name Bison antiquus 
was proposed, f 
Dr. Leidy, also, in his memoir directed attention to the 
fossil horn-cores described by Dr. Carpenter, of which a con- 
densed statement follows, and stated that they appear to be- 
long to the same species described by Harlan as Bos latifrons. 
Dr. William M. Carpenter, of New Orleans, described in 
January, 1846,^ some fossils collected by Mr. William Huff 
from the banks of the Brazos river, near San Felipe, Texas. 
Amongstthem were remains of an "ox," consisting of the front-
