Show 1875.] MR. W. T. BLANFORD ON A NEW STAG. * 637 nished only with a short roundish prolongation on the fore part of the first lobe, and not with three as in the Patagonian species. The incisors are narrow and clear yellowish on the anterior surface, With respect to the three lobes of the first molar in the under jaw of Dolichotis patachonica, I may mention that this configuration is only found in very old specimens ; in the young which have fallen under m y notice there are only two lobes-the first with an oval prolongation in front as an accessory appendage, which becomes longer with age and is at last separated from its lobe, but remaining always smaller and with more rounded angles than the other two lobes. W e have in tbe Public Museum skulls of different ages which clearly prove the gradual separation of the accessory lobe. In the new species the first lobe of the same molar in the under jaw has a similar but not so well developed prolongation in front, which may also be separated from the main lobe with age. Both m y specimens are very young and show clearly the construction of the skull. Buenos Aires, August 8th, 1875. 2. On some Stags' Horns from the Thian-Shan Mountains in Central Asia. By W . T. BLANFORD, F.R.S., F.Z.S., &c. [Received October 28, 1875.] Amongst tbe collections brought back by the expedition to Western Turkestan, to which the late Dr. Stoliczka was attached as geologist and naturalist, were several large Stag-horns said to have been brought originally from the Thian-Shan mountains. Like most of the finest and most valuable specimens in the collections, the greater number of these horns were dispersed after Dr. Stoliczka's death, and passed into private hands ; but one pair of shed horns, which, although not belonging to the same animal, closely resemble each other in form and size, remain in the collection belonging to the Government, and have been intrusted to me for examination. I was at first indisposed to give more than a general description of these horns ; and in the list of Dr. Stoliczka's mammalian collections which I read to the Asiatic Society of Bengal in August last, I did not attempt to name them. But as the horns are very fine, and appear clearly to show the existence of a species hitherto undescribed, I think I may be justified in giving a fuller account of them, and proposing a name for the animal to which they belong. The horns are of very large size, each measuring 51 inches in length round the curve; and one is 10*9, the other 10*5 inches iu circumference just above the burr. Each shows seven well-formed points or tines, besides which one of the horns has a rudimentary bifurcation on the fourth and fifth tines, counting from the base. The beam is much curved ; and, so far as can be judged from the |
