Show 24 DR. J. E. G R A Y O N T H E SUIDAE. [Jan. 9, at occiput 8| inches (see Miiller, Verh. t. 32. f. 3, 4). Nose rather broad behind, tapering from the orbits, more compressed in front; concavity on cheek very deep ; forehead convex; zygomatic arch very large, swollen, convex externally. The side of the lower jaw much swollen and prominent. The nose of this skull is much wider than that of the skull from Ceram (712d). No. 1362a. An adult skull, without cutting-teeth and canines, and rather broken on the nose, received from Mr. Wallace as the skull of S. vittatus from Borneo, is very similar to no. 712 c from Java, 14| inches long, 8 | inches high at the occiput. The forehead not quite so convex; but in almost all other respects they agree, except that the sides of the lower jaw are not so much swollen aud convex. These skulls are known from those of S. vittatus by the concavity in the front of the orbit being very deep, ovate, and narrow behind, instead of broad and square (that is, ending in a nearly straight line). Three other adult skulls, apparently belonging to the same species, were received without any habitat (but probably from Java or some other Dutch colony) from the Utrecht Museum. One is 15 inches long, 9| inches high at the occiput ; the second 16 inches long, 9f inches high at the occiput; the third, length 15, height at the occiput 8% inches. Var. ceramica. No. 712d. Skull, adult. A Wild Boar from Ceram, collected by Mr. Wallace. Length 15 inches, height at occiput 8 inches. Nose tapering, very narrow, compressed and deeply concave on each side in front of the orbits ; the zygomatic arch large, swollen, and convex externally ; the crest on the sheath of the upper canine is narrow and short. No. 712/. A n adult skull, obtained from the Utrecht Museum, named " Sus larvatus," without any habitat, which is very like 712d from Ceram, but considerably larger, being 16^ inches long and 8f inches high; the nose is broader and rather wider in front over the canines ; the crest on the hinder part of the sheath of the upper canine is similar, smaller, but thicker. In both skulls the crest on the canine is much shorter and less marked, and the sides of the lower jaw are swollen, but not so swollen and convex as in 712c from Java. The specimen from Ceram (712a7) differs from all the others in the nose being much narrower, more compressed, and apparently longer compared with the length of the brain-case. Otherwise the four skulls from the Utrecht Museum and the one from Java (712c) are all very much alike. Mr. Blyth considers his Sus ceylonensis (Journ. Asiat. Soc. Beng. xx. 173; Sus zeylonensis, Blyth, M S . photogr.) a variety of S. barbatus, which he says has been introduced from Borneo to Ceylon. Judging from the photograph of the skull, which has Sus zeylonensis written on it, it is much shorter and thicker than the skull of S. barbatus. The photograph is much more like that of Sus verrucosus. |
