Show 658 MR. K. SWINHOE ON THE [DeC 9, then backwards. The beam inclines backwards and upwards, and then curves gradually forwards and sidewards. In the three-year pair the bony pedicle sinks in height, and the brow-antler lengthens greatly, making a deeper cleft; the horns incline from each other at a much greater angle; the hind snags lengthen and become more lateral, and the points are much larger; the beam the while remains much the same in length and thickness. The measurements are- inches.

The postlateral snags become still more lateral, and a rudimentary tine shows itself on the inner side of the right brow-antler, near the cleft. Measurements. , inches.

But the Museum has also horns from unknown localities, which resemble our Hainan specimens in the shortness of the hind snag and the prolongation of the fore snag; and in Mr. Flower's possession I have seen horns which agree closely with mine. Mr. Flower's specimens were received from Mr. Blyth, but, unfortunately, it is not known in what part of India they were collected. The horns of the Formosan Sambur (C. swinhoii) are of much the same form as those of the Hainan race, |
