280 MR. BUSK ON THE REMAINS OF 
character, the value of which has been already adverted to in speaking of the larger 
humerus, appears to me of great importance in this comparison, viz. the angularity on 
the posterior aspect of the upper part of the shaft, and the well-marked depression 
on the inner side of the posterior angle, both of which are also well marked in the 
larger humerus, fig. 26. The nutrient foramen, in this little bone, is situated on the 
inner border, about 0'-75 above the inner condyle. As the corresponding part in the 
larger humerus is broken away, the site of the foramen cannot be positively determined ; 
but as it does not exist in any other part of the bone, it could not have been placed very 
far from the same spot as in the foetal bone. I have little hesitation, therefore, in refer- 
ring this humerus, fig. 49, to a very young LZ. falconeri. The young humerus shown in 
fig. 50 is less entire at the upper end; but at the lower a considerable part of the epiphy- 
sial surface remains. What is left of the shaft is sufficient to show that in the upper 
part it is more rounded, as in the African Elephant, and that the supinator, or external 
condyloid ridge, is not continued upwards, as it were, into a posterior angle as it is usu- 
ally in the Indian Elephant. So far as can be judged from the imperfect condition of 
the humerus fig. 49 at that part, the inner condyloid ridge is- much thicker in the 
antero-posterior direction, and the inner border of the bone consequently more rounded, 
in fig. 50. In front also the anterior surface of the deltoid crest is much more oblique 
than it is in the humerus fig. 26, in which a well-marked angle, prolonged downwards 
from the anterior or external border of the bicipital groove, bounds internally a perfectly 
flat surface in front of the deltoid crest. ‘The same angularity, it should be stated, is 
visible, though of course less marked, in the young humerus of E. falconeri (fig. 49). The 
nutrient foramen is in the same situation as in the former specimen. ‘The humerus 
fig. 50 shows slight marks of gnawing, as by a small rodent, on the hinder surface. 
Another fragment of a much older but still young animal, is a fragment of the lower 
end of the right humerus, broken obliquely through the shaft about 45 above the 
middle of the lower epiphysial surface, a portion of which remains. So far as it admits 
of comparison, its characters accord with those of the humerus of £. falconeri ; and it is 
not unreasonable to suppose that the bone may have formed part of the skeleton of the 
same animal as the femur fig. 29. In it the want of roundness in the internal condy- 
loid ridge behind is well marked. 
The only other young bone belonging to the anterior extremity of which there is 
any specimen is the radius, of which bone there are two examples. They are figured in 
Pl. XLVIL. figs. 18 & 19, both belonging to the same side. One is of larger proportions 
than the other, and not improbably, though by no means certainly, of rather more 
advanced age. Both bones are broken across at the corresponding point, which is the 
slenderest part of the shaft, or about three transverse diameters of the lower epiphysial 
surface above that end. At this point the contours of the transverse sections differ a good 
deal, and show that the shaft of the larger radius (fig. 18) is much more compressed 
than the other, and particularly that the outer or, rather, anterior edge is very
