HYENA SPELAA. 155 
Another fragment of a skull from the same locality 
indicates a younger Hyena spelea, by the smaller size of 
the sagittal and occipital crests, and the limited extent 
of the frontal sinuses, which are not continued backwards 
beyond the frontal bones. 
A left ramus of the lower jaw of the Hyena spelaa 
from Oreston, corresponding in size with the larger frag- 
ment of the skull, differs from the Hyena crocuta in the 
greater relative breadth of the posterior ridge of the second 
premolar tooth. Mr. Clift* has figured a portion of the 
lower jaw of a young Hyzena, ‘‘in which remain one of the 
shedding teeth, and two permanent ones, which had not 
sufficiently advanced in their growth to have protruded 
through the gum, but are still enclosed within their alveo- 
lar cavities.” 
The Oreston specimens of the Cave Hyzena were found 
in the fissure marked p, fig. 50, p. 132. 
Two canine teeth, much worn, of the Hyana spelaa 
are recorded by Dr, Buckland to have been discovered, 
associated with the remains of the A/ammoth and Rhino- 
ceros, in the cave of Crawley rocks, near Swansea; these 
fossils are preserved in the collection of Miss Talbot at 
Penrice Castle. 
In the same collection is preserved the lower extremity 
of the left humerus of the Hyena spelea from the cave 
at Paviland, on the coast of Glamorganshire, noticed above 
at p. 124. 
Numerous and highly characteristic specimens of the 
Hyena speleaa have been obtained from the caves and fis- 
sures of the mountain limestone at Bleadon, and near 
Hutton and Banwell in the Mendip Hills. 
Remains of eleven or twelve Hyzenas were discovered by
