LEPUS TIMIDUS. OANA 
‘ Reliquize,” has, he says, ‘‘ the size and shape of that of a 
Hare :” the metatarsal bone, PI. x. figs. 15 and 16, is that 
of the outer toe, and is nearly as long as that of a Hare, but 
is proportionally thicker. Cuvier adds, that he himself 
possesses a first phalanx of the hind foot from Kirkdale, 
which is also a little thicker in proportion than in the 
Hare ; but the distal end of a tibia from the same cavern, 
exactly resembles the corresponding part of the Hare, and, 
with regard to a portion of jaw, he says, ‘‘ I cannot per- 
ceive any difference that can be regarded of a specific 
nature ;” and concludes that, ‘‘if these fragments apper- 
tain to a known species, it must be the Hare; the Rabbit 
would have them smaller and more slender.” 
The fossil lower jaws, from both Kirkdale and Kent’s 
Hole which I have examined, have presented a somewhat 
shorter interspace between the molars and incisors, than in 
the common Hare of this country, with the same propor- 
tions of depth and other dimensions, and the same sized 
teeth; whereby it would appear that the Hare of the 
caves had a rather shorter head, and resembled in that 
respect the variety or species to which the name of Lepus 
Hibernicus has been given, and which has also somewhat 
stouter limbs than our English Hare. 
I cannot detect any difference between the fossil Hare 
and the Irish Hare in the forms and proportions of the 
bones of the extremities: a very little increase of thick- 
ness being all that distinguishes the Irish from the English 
Hare in these parts of the skeleton. 
Fossil remains of a Hare have been discovered by Croizet 
in the tertiary strata of the Puy de Dome; by Serres, in 
the ossiferous caves of Montpelier, and by Schmerling in 
those of the Province of Liége.
