covered near Columbus, Ohio, and also of the two living 
species of peccary, D. torquatus of Mexico, and D. labiatus 
of South America, for comparison, as likewise of the com- 
mon hog, Sus scrofa. He described the mode of occurrence 
of these highly interesting fossils. They were found in two 
groups of six specimens each, about a rod apart, buried in 
the valley drift of a small stream tributary to the Scioto; and 
from the fact that all the heads were turned in the same 
direction, it would seem as though the animals had been 
sleeping under the edge of the steep bank, which had caved 
in and buried them. 
The size of this extinct species was a little larger than 
that of the living D. labiatus. The circumstances of their 
occurrence hardly allow us to assign them any more definite 
date than Post-tertiary. They probably belong to the same 
period with the elephant and mastodon, which, appearing 
shortly after the glacial epoch, continued down for some time 
into the present geological age. 
November 24th, 1873. 
President Newberry in the chair. Ten persons present. 
THE PRESIDENT made some statements respecting the ar- 
ticle of Prof. Lesquereaux upon the lignite-flora of the far west, 
in the Report of the U. S. Geological Survey of the Territories 
for 1872. In this extended paper, Mr. Lesquereaux takes 
the ground that nearly all the lignites of our far West are 
Eocene, whereas the evidence is conclusive that much of what 
he so regards is Cretaceous, and much is Miocene. The 
lignites of Nebraska, Kansas, and the Indian Territory, at 
first held to be Tertiary by Profs. Heer and Lesquereaux, are 
now conceded to be Cretaceous, as the speaker had originally 
pronounced them. As to those of Arizona and New Mexico, 
he had become familiar with them during a two years’ resi- 
dence, and the evidence of their Cretaceous age, from over- 
lying marine fossils, is unquestionable. The same is the
