The inferior canine is represented by a crown. It is remarkably short, 
and stout at the base; the posterior outline very concave. The usual 
obtuse keel is seen on its anterior inner aspect, and worn surface postero- 
exteriorly. The apex of the crown is worn by use. The smaller pre- 
molars have not been recovered, but the last or sectorial has left its 
impression in front of the first molar in place in the matrix, and appears 
to have been of the proportions seen in the grizzly bear.

In size this species probably equalled the grizzly bear, as the teeth are 
as large as those of any of the numerous crania in the Museum of the 
Academy Natural Sciences, though Prof. Baird gives measurements of 
some in the Smithsonian collections, which are larger. Should the teeth 
be related to the skeleton as in our black bear U. americanus, a still larger 
size is indicated. The nearest relationship in the characters of dentition 
is to be seen in the U. bonacrensis, of Gervais* of Buenos Ayres. It has 
the peculiar form of the first molar seen in U. pristinus, but differs spe- 
cifically in that of the second, which is interrupted in one of its outlines 
and rather more tubercular. 
As compared with Ursus amplidens, Leidy, the following relations ap- 
pear. The last molar has a smaller crown than in the type specimen of 
the latter. In U. pristinus, and the last is between .50 .75, the length of 
the second molar; in U. amplidens, exactly as in U. horribilis, five-sixths 
length of crown, or equal the extent of alveole. The third molar is less 
contracted behind in the type specimen of U. amplidens. The latter 
species appears to be in many ways nearly allied to the grizzly bear. 
The discovery of this species by Mr. Wheatley, in Pennsylvania, is par- 
ticularly interesting, as fixing an extended range for it, and proving that 
our cave bear is totally distinct from that of Europe, and rather of the 
type which was associated with the gigantic sloths in the southern re- 
gions of South America, at the same geologic epoch. 
Feruis, Linn. 
Two proximal phalanges of a species of this or an allied genus, were 
found by Mr. Wheatley. They pertained to an animal of the size of the 
jaguar, (Felis onca). A fragment of a canine tooth indicates a cat as 
large as the tiger, but is too imperfect to allow of determination, Some 
yertebre of a carnivorous animal, perhaps of a dog, were also found.
