4. There is a very decided flattening of the inner side of the head, with a far more 
rounded and convex external aspect, both of which are very apparent when the four 
bones are placed side by side. With respect to the two latter features it may be stated 
that the same obtains in the adult bones (Pl. XV. figs. 1 & 3), which, however, in 
regard to the hollowing below the head behind are distinctly more like the former. 
5. The external condyloid aspect is seemingly narrower than in the former; but I 
feel, in the absence of more perfect materials, that I should be verging on hyper- 
criticism to pronounce a decision on a point which gives so distinctive a character to 
the same parts in the two recent species. 
As compared with the immature bones described by Mr. Busk, I find that the two 
former agree with his pl. 47. figs. 16 & 17, and the latter with his figs. 15, 20, & 21. 
He alludes to the nutrient foramen being placed higher up in the latter, This there is 
no means of proving, from the loss of the parts in which it exists; but in the Zebbug 
specimen in my possession, equivalent to Pl. XXI. fig. 14, it is placed in the lower third, 
and therefore in the position assigned to it by Busk. 
X. FIBuna. 
1. The largest specimen of this bone is represented by the distal extremity (Pl. XV. 
fig. 4), As regards dimensions, it is in accord with the tibia (figs. 1 & 2) and astragalus 
(Pl. XVI. fig. 1), so much so that in all likelihood all belonged to the same individual, 
as they were found together. This distal end of the fibula has much the character of 
the African, the lower margin being slightly concave. Here the obliquity on the tibia 
just indicated is repeated on this fibula. 
2. The smaller distal extremity (Pl. XV. fig. 5) is one of two perfect specimens 
(right and left) found near each other in Mnaidra Gap; they do not differ whatever in 
dimensions, and probably belonged to the same individual. Here we find the lower 
margin deeply notched as in the Asiatic. The tibial facet is not shown in the figure, 
but is well defined on the bone, and is scarcely so oblique as in the last, and measures 
2:3 inches in breadth by 0°8 inch. Both figs. 4 & 5 represent the characters of old 
bones, although the latter has been broken across at its lower epiphysis. The former 
represents an individual of the largest dimensions above stated; the latter, one having 
an astragalus of the dimensions of Pl. X. fig. 10, which will be shown to have some 
characters in common with the Asiatic and Mammoth rather than the African. 
3. An entire detached fibula was discovered in Benghisa Gap, belonging doubtless to 
the smallest form; the epiphyses were completely consolidated ; and, like the others, it 
displayed all the characters of an old bone. The entire length was 8°6 inches, girth of 
the proximal end 2°5, girth of the mid-shaft 2, girth of distal end 4:4, breadth of distal 
end 2°6. A detached distal end of another fibula from the same situation measured 
22 inches in breadth.
