112 MR. G. BUSK ON THE ANCIENT OR 
the form of the trochanter and of the digital fossa behind it, these bones correspond 
exactly with the femur of C. elaphus, in which the diameter of the head is 12; in 
C. barbarus 1""1. Although found at a considerable depth in the Genista fissure, these 
two specimens, from their light porous condition and the complete absence of stalag- 
mitic deposit, cannot be supposed to belong to the most ancient fauna, and are 
probably referrible to the human period. Not so with the few other remains of the 
femur, which consist of— 
2. Three portions of the shaft, between five and six inches long, and all with a least 
circumference of between 3-2 and 3'-4. That they are cervine, and do not belong to the 
gigantic form of Jéex met with in the breccia, is proved by the great extent and depth of 
the pit behind the inner condyle and the strong development of the linea aspera. The 
only other two specimens consist of the distal end, with the articular portion complete. 
The dimensions of this end in one case are 3"*5 x 2!'"7, and in the other 3"°3 x 2!"4. In 
C. elaphus the corresponding dimensions are 3-3 x 2!"5, and in C. barbarus 3!"-1 Xx 2!"2. 
All these specimens are thoroughly fossilized, and they were thickly incrusted with 
hard ferruginous stalagmite. 
9. Tibia. 
Portions of fourteen or fifteen tibie are preserved—some extracted from the hard 
breccia, others more or less free, but all coated to some extent with crystalline stalag- 
mite. Six of the specimens consist of merely the shafts, without either articular end. 
One has the distal epiphysis detached ; and, from the general character of the bone, it 
would appear to have belonged to the same animal as two of the metacarpals above de- 
scribed, to which also may perhaps be assigned a metatarsal of the same age and in the 
same condition. ‘The least circumference of these shafts varies from 3'°5 to 2-7, the 
younger-looking bones being, of course, the slenderer. 
There are two fragments of the proximal end, in one of which the epiphysis has been 
detached, and the surface is covered with thick incrustation; in the other instance the 
proximal articular surface is entire, and measures 2”-7 x 27. 
Several examples of distal portions, with the trochlea, give the full characters of that 
part. As is the case with the other bones, these specimens, as regards the articular end, 
vary in size from 1°31" to 15 x 1'"9, the intermediate forms being 1-3 x 1-8 and 
14x19. Into the smallest of these specimens the astragalus of a Highland Stag fits 
so exactly that both might well have belonged to the same individual. 
It is impossible to distinguish any of them from the tibia of C. elaphus. But besides 
the above there are two proximal fragments with the articular surface entire, which 
measures only 2-1 x 25, and which would seem to be referrible to C. barbarus, in which 
the surface in question measures 2’-4X 25. Both of these specimens are in the same 
mineral condition as the rest, although one is said to have been found above the 
stalagmite floor of Genista Cave, and the other at a considerable depth in the East 
Fissure.
