“I was much disappointed at not getting a shot, but I was sure they would not leave the plateau, and determined to leave no stone unturned to come up with them. We tramped on in the direction they had gone, and after going about half a mile caught sight of them again; but they had seen us first, and were going hard at about 250 yards when we saw them. It would have been a very fluky shot, and I held my hand. I could now distinguish four females and one buck, which appeared to have horns exactly like a Gazelle, between 8 and 10 inches long. “When they were fairly under weigh we got a bush between us and them, and hurried after them as quick as we could. After a few moments, as luck would have it, they all stopped in a bunch and turned round with their heads towards us at about 300 yards. I could not distinguish the buck at the moment, as they were standing among bushes and were not distinct, but I aimed at one which turned partially broadside and fired. The animal fell dead, and the other four streamed away out of sight. On running up I found that it was a female that I had killed, and I am sorry to say that on grallocking her we found an almost mature embryo inside her. I was unable to preserve this as I had no spirit with me, but the fact shows that the animal killed was an adult. “I took careful measurements on the spot, and found the height at shoulder 23 inches; distance from the nose to the root of the tail 33; the tail including 2-inch hair 5½; the length of ears in front 6¼, and their breadth 2¾.” Sir Edmund Loder has kindly favoured us with the following field-notes on the Beira:-- “Mr. Percy Aylmer heard of this Antelope on the stony foot-hills in Gubau (N. of Hargaisa), and saw it on one of the isolated foot-hills to the south of Gau Libah. Mr. A. E. Pease and I found it on another detached hill about 20 miles west of this. This particular hill was extremely rough and rugged, covered with loose boulders, making walking and silent stalking extremely difficult. This hill was also frequented by Gumbouri (Wild Asses, _Equus somalicus_), which, from their large size, were easily seen. The case was, however, very different with the ‘Baira,’ which, at a comparative short distance, seemed to melt out of sight immediately they stopped moving, and indeed when they were in motion it was rather the moving black shadow cast by a tropical sun that caught the eye than the animal itself. They were observed by us in bands of seven, three, and three. In the two lots of three which I saw there was what I take to be one adult male with each. The only record of height that I can lay my hand on at this moment is that of an adult female, which measured at the shoulder 2 feet 2 inches; probably the male would be an inch higher.
