Show 764 MR. A. H. GARROD ON LOPHOTRAGUS MICHIANUS. [Nov. 21, a minor sulcus. There is a break in the sulcus which separates the middle and inferior external gyri a little more than an inch from the anterior border of the hemisphere, which is peculiar. As in Moschus and in Cervus humilis, the calloso-marginal sulcus appears on the superior surface of the brain, allowing the hippocampal gyrus to appear between it and the middle line. In Cervulus muntjac the convolutions are slightly less developed than in Michie's Deer, and the calloso-marginal sulcus is even more superficial; it is, however, narrower anteriorly. In its generative organs, the glans penis (fig. 3), instead of being blunt, is an elongated and slender cone, terminating much like the tip of a wooden pen-holder, the urethral orifice being situated just behind the extreme tip, slightly turned upwards. The Muntjacs and the Roe Deer agree with Michie's Deer in the shape of the glans; but whereas there is no trace of Cowper's glands in Capreolus and Michie's Deer, they are large in Cervulus (in C. muntjac at least). There are four nipples. On the outside of the skin covering the metatarsus I found in the recently dead animal a deep smegma-secreting depression, evidently homologous with the metatarsal glands in most Cervidae. There were no tufts of hair round these ; and I cannot recognize their situation in the prepared specimen of the skin. General Bemarks. From what has been said above, it is evident that the Lophotragus michianus of Swinhoe is the same animal as the earlier-named Elaphodus cephalophus of A. Milne-Edwards, and that it was because his specimen was a female in which the skull was wanting, at the same time that the figure given by M. Milne-Edwards is from a remarkably light-coloured and red skin, that Mr. Swinhoe was misled as to its affinities. It seems, however, that the Ningpo animal is of a greyer tint than that from Moupin; for the description given by Mr. Michie*, namely that "it is a dark iron-grey or pepper-and-salt colour, like some Scotch terriers," exactly applies to the Society's example, whilst the Paris skins are all decidedly chocolate, although differing in tint among themselves. As to the affinities of Elaphodus cephalophus, M . Milne-Edwardsf has remarked that " it is intermediate between the Muntjacs and the ordinary Deer, in certain respects appearing even to unite these animals to Hydropotes and Moschus." That Moschus has any close affinities with Cervulus and its allies is extremely doubtful; and a comparison of the above description of * P. Z. S. 1874, p. 453. f Loc. cit. p. 353. |
