1916-17.] The Bone-Cave in the Valley of Allt nan Uamh. 345 
The Otter is represented by a few bones from Bed 3, and the Badger 
by a skull and several bones from the same horizon, but there is always 
the possibility of the latter animal having burrowed into the deposit at 
a later date. The Stoat and Weasel have been found in Bed 5, parts of 
skulls and limb-bones of both species having been met with. A single 
caudal vertebra of a Fox alone represents that animal. 
Portions of Red-deer and Reindeer antlers occur in this cave, and similar 
remains have been recorded from many deposits of prehistoric and modern 
date in various parts of Scotland, where Reindeer were still living in the 
twelfth century. 
There are a few limb-bones of a large Hare ; and as no such fossil 
remains appear hitherto to have been recorded from Scotland, it is of 
peculiar interest to ascertain, if possible, to what species and variety these 
belong. The specimens available for comparison are a femur and a 
humerus, both nearly perfect, and an upper incisor tooth. There are also 
portions of a tibia, an ulna and some foot-bones, but these do not give 
much help. The femur and humerus both present characters of their 
proximal ends which at once show their affinity to the Variable Hare ( L . 
variabilis) rather than to the Common or Brown Hare (Lepus europceus ) ; 
and the incisor tooth has cement in its anterior groove, thus pointing to 
a similar affinity. It is not easy, however, to decide to which variety of 
L. variabilis these remains should be referred, and this determination rests 
chiefly irpon measurements. One naturally, in the first place, compared 
them with the modern Scottish Blue-hare (now called Lepus variabilis 
scoticns), but the bones of my own example of this species were so much 
smaller and more slender than the Assynt bones that it seemed unlikely 
they could be the same. Length of Assynt femur, 132 mm. ; Scotch Hare, 
115 mm. Length of Assynt humerus, 111 mm.; Scotch Hare, 92 mm. On 
further comparison with measurements of specimens in the College of 
Surgeons Museum, given by Mr Martin A. C. Hinton in his masterly 
paper on Fossil Hares (Sci. Proc. R. Dublin Soc., vol. xii, N.S., p. 225, 1909) 
and with specimens of Russian Variable Hares in my own collection, I find 
that there is a considerable overlap in the sizes of these varieties. The 
largest Scotch Hare is very nearly as large as the Assynt fossil ; but on the 
other hand some of the Russian L. variabilis are smaller. As a matter of 
fact, the Assynt humerus is longer and the femur more robust than are these 
bones in the largest of my Russian specimens, and approach the dimensions 
of the Kentish fossils given by Mr Hinton. There remains, therefore, a 
doubt regarding the variety represented by these Assynt remains, and this 
will, I think, be best shown by recording them as Lepns variabilis scoticns ?
