THE MALTESE FOSSIL ELEPHAJSTTS. 55 



1. The radial and ulnar distal apophyses (PI. XIII. figs. 2 & 3) evidently belonged to 

 the same individual. I shall describe them as being the smallest bones of the forearm, 

 referable to the radius and ulna of the smallest Elephant. Fig. 2, left radial epiphysis, 

 shovv's a deep concavity for the lunare, which^n turn will be shown to present a corre- 

 sponding convexity in contradistinction to more shallow and even surfaces in the largest 

 specimens. The Asiatic seems to display the former characters, and the African the 

 latter. The projection for the scaphoid, usually prominent in the adult recent and in 

 the following larger fossU specimens, is not observed at a in fig. 2, the surface being 

 .xounded instead of angular. 



2. With reference to the right ulnar epiphysis (fig. 3), it is seemingly remarkable for 

 the concavity and smallness of its cuneiform aspect. The radial facet (a) is 1 by 0-7 

 inch in breadth. As compared with recent species, there are no specimens at all equal 

 to the small dimensions of the above, with at the same time their epiphysis in any wise 

 so matured, which shows fig. 3 to have belonged to a nearly full-grown small Elephant. 

 The cartilaginous epiphysis of the young Asiatic (No. 2723, R. C. S.) agrees well as to 

 relative dimensions, the height of the latter individual being 4 feet. 



3. Another radial epiphysis, in every respect similar to fig. 2, but somewhat larger, 

 displays the pronounced hollow on its lunare aspect to a greater extent. The difi'erences 

 in dimensions are noteworthy, the lunare facet in fig. 2 being 2-4 inches by 1-8, whereas 

 in the above it is 2-8 by 2 inches — thus indicating Sin individual of the dimensions of 

 707 H, Asiatic, in the British Museum, which, I calculate, stood about 5 feet high. 



4. A still larger distal extremity, with a less determiaed lunare convexity and hollow, 

 gives an articular aspect of 3 by 2-3 inches. 



Finally, PI. X. fig. 6 shows the largest specimen, the lunare aspect of which is 3-4 

 by 2-8 inches. The angle for the scaphoid {a) is pronounced in this specimen as in the 

 two preceding, forming a well-defined border on the imier side, of 1-2 by 0-5 inch. As 

 compared with PI. XIII. fig. 2, the articular aspect is seemingly less hollowed out, with 

 a less prominent convexity, which is repeated, as just observed, in the largest lunaria. 

 The distal extremity of the Sumatran is somewhat larger than fig. 6, which might 

 therefore represent an elephant 6-5 feet in height. 



Besides the distal uhiar epiphysis just referred to, there is the upper fragment of a 

 shaft referable to an immature individual, and represented on PL X. fig. 9 (half) and 9 a 

 (natural size). As compared with recent species and the specimens described by Busk 

 from Zebbug ', it presents a few important characters. The olecranon-spine is sharp in 

 the Asiatic; and, as far as the single instance in the British Museum admits, it would seem 

 to be more or less rounded in the African ; the same obtains in an uhia of H. antiquus ; 

 in fig. 9 it is very sharp. Again, from the undulating contour of the head of the radius, 

 the radial sulcus is seemingly wider in the African than in the Asiatic ; and this explains 

 the larger outer condyle in the Asiatic ; moreover the concave external side of the
