1875. ] MR. W. T. BLANFORD ON A NEW STAG. 637 
vished 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 sur- 
face, 
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 my notice there are only two lobes—the first with an oval prolon- 
gation 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. We have 
in the 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 my specimens are very young and show clearly the construc- 
tion of the skull. .

2. On some Stags’ Horns from the Thian-Shan Mountains 
in Central Asia. By W. T. Buanrorp, F.R.S., F.Z.S., 
&e. 
[Received October 28, 1875.] 
Amongst the 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 pro- 
posing 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 in 
circumference just above the burr. Each shows seven well-formed 
points or tines, besides which one of the horns has a rudimentary 
bifureation on the fourth and fifth tines, counting from the base. 
The beam is much curved; and, so far as can be judged from the
