RHINOCEROS LEPTORHINUS. 371 
the nasal bones are broad, long, straight, horizontal, not 
massive, but strong and ‘élancés, without a septum 
below (‘ sans cloison en dessous’), abruptly bent down near 
their free extremity, which terminates in a point directed 
downwards and a little forwards,” 7. p. 77. The marked 
difference in the form of the cranium of the 2h. leptorhinus, 
besides that essential structural one in the presence of the 
osseous septum, will be appreciated by comparing the con- 
tour of the nasal platform in fig. 131 with M. Christol’s 
figure and accurate description of the same part in the 2h. 
Schleiermacheri. Cuvier deemed the skull of this species to 
resemble that of the Sumatran two-horned Rhinoceros 
more than any other, but to be proportionally shorter, with 
the nasal platform broader and less pointed, its convexity 
more prominent, and the temporal ridges more approxi- 
mated, so as to form a sagittal crest. (Tom. cit. p. 502.) 
Now, in each of these particulars, the RA. Schleiermacheri 
equally departs from the 2h. leptorhinus; which, by its 
proportionally longer cranium, with a narrower and more 
gradually attenuated nasal platform (fig. 139, 7), pre- 
senting a more gradual and less elevated convex curve 
(fig. 131), and with the flat space intervening between 
the less approximated temporal ridges, still more nearly 
resembles the skull of the RA. Sumatranus than does that 
of the Rh. Schleiermacheri. The Rh. leptorhinus differs, 
nevertheless, from the A. Swmatranus (see Cuyv., op. cit., 
tom. ii., pl. Ixxix., fig. 3) in its proportionally longer and 
narrower cranium, in the more backward production of the 
occipital ridge, and still more essentially by the ossified sep- 
tum and its confluence with the fore-part of the nasal bones. 
From the skull of the Rhinoceros incisivus, to which Cuvier 
erroneously supposed that of Schleiermacher’s species to 
belong, our present specimen is readily distinguished by
