Show 760 MR. A. H. GARROD ON LOPHOTRAGUS MICHIANUS. [Nov. 21, obligingly allowed me to remove the cranium from the skin of the female that he has lent me, which fortunately happens to be of exactly the same age as the Society's male ; in other words, the median milk-incisors are gone, whilst the third molars are just protruding, all the milk-molars being in place. In the Society's specimen the frontal pedestals are fairly long, but without any antlers at their extremities. Their bases are slightly further from one another than in the Moupin male; and there is a second slight difference from both it and the female, which is, that just at the root of the ascending orbital process of the malar bone the ring of the orbit does not become ossified upwards so as to reduce its size by the formation of a shallow lamina above the masseteric ridge. This peculiarity may also be expressed by saying that the surface of origin of the masseter muscle extends upwards as far as the margin of the orbit in the Ningpo male, whilst in those from the more western locality it ceases some distance below it. But it must be noted that the Ningpo specimen died in very bad condition, the bones being spongy and ill-marked*, whilst the others were shot wild. In it, strangely enough, there is also an abnormality with which I am not at all acquainted. It is that the malar bones O H both sides, instead of being single, are made up of two independent parts, an orbital and a zygomatic, with the suture longitudinal and nearly straight, extending from the anterior extremity of the zygomatic process of the temporal bone to the posterior inferior part of the large crumenal depression. Sir Victor Brook et, in his paper on the Cervuli, has drawn attention to the very peculiar distribution of the ankyloses in the tarsus of that family, he having demonstrated that in it the external and middle cuneiform bones blend with the naviculo-cuboid to form a single bone. The same condition exactly exists in Elaphodus cephalophus, the innermost cuneiform bone remaining free. But, strange to relate, in my specimen of Michie's Deer, on both sides, this internal cuneiform bone is completely anchylosed with the metatarsus, a further specialization than is found in any other ruminant, so far as I can make out. In Michie's Deer no trace of the lateral metacarpal rudiments could be detected. It possesses thirteen pairs of ribs, six lumbar vertebrae, six ankylosed sacrals, and nine caudals, making forty-one * The following are the measurements of the skull of the Ningpo male, side by side with which those of the male (adult) Moupin specimen are given, from M.
