170 CARNIVORA. 
lished in the ‘ Paleontological Memoirs,’ vol. ii. p. 467, 
where it is also figured, pl. xxxvi. figs, 3, 4; the alveolus 
of pm.3 is present. This specimen is remarkable for the 
excessive width and shortness of m. 2, which led Falconer 
to believe that it could not be referred to any species of 
Bear with which he was acquainted. This width is, how- 
ever, scarcely greater than that of the corresponding tooth 
in No. 47678, from which it may be inferred that the 
present specimen perhaps belonged to the present species, 
if the Gibraltar specimens belong to the same. The 
present specimen is, however, very different from typical 
forms of U. horribilis ; and if it belongs to that species it 
indicates a great range of variation. Its molar is very 
similar to that of U. arctos, No. M. 231. 
Presented by Gen. Wood, 1865. 
16816. Two canines, probably belonging to this species; from 
Kent’s-Hole Cavern, Torquay.

from the Pleistocene of Grays. Purchased, 1848. 
16816. Canine, probably belonging to this species; from Kent’s- 
Hole Cavern. McEnery Collection. Purchased, 1842. 
M. 267. Fragment of the mandible containing the canine ; from the 
(Iig.) Pleistocene of Grays. This specimen is figured by Morris 
in the Ann. Mag. Nat. Hist. for 1838, p. 548, under the 
name of U. speleus; but there seems little doubt that 
it belongs to the present species. 
Purchased from Prof. Morris. 
M. 1624. Cast of a fragment of the left maxilla, containing the second 
and third true molars. ‘he original of this specimen is 
from an ossiferous fissure at Windy Knoll, near Castleton, 
Derbyshire °. Presented by Prof. Boyd Dawkins.
