THE SEROW IN STAM. 25 
out—to end of tail 60 inches, and heieht at shoulder 36 inches. I 
should say the weight would have been about 140 Ibs. The horns 
of a male and of a female shot by me measured 84 inches and 82 inches, 
respectively, in length along the outer front curve. The depth of the 
curve, which is but slight, would be only about an inch between the 
inner side of the curve and a straight line drawn from tip to base. I 
should say that any horns over 9 inches in length would be quite 
exceptional in Siam. 
I can see no great difference in the size, weight of body and 
lenoth of horns of the male and the female Serow. In both sexes the 
tail is very short, not longer than 6 inches as a rule, while the ears ara 
large, about two-thirds as long as the horns. The neck is short, and 
carries a short dark grey mane of coarse, straight hair, as a rule erect 
and about 6 inches long, which extends to between the shoulder blades, 
where it shortens in length to a ridge of longish hairs along the back- 
bone. The hair of the body generally is coarse, and does not form a 
very thick coat in this climate, but probably it is longer and thicker 
ina colder one. On Mr. Butler’s specimen the hair seems to me to be 
longer than is usual. Possibly this is because the other pelts I have 
seen were those of animals shot in the hot season, and his specimen 
was shot in November towards the end of the rains. The hair may 
grow longer in the wet and cold season, and may be moulted in the 
dry season. The young Serow are darker than the old ones, which 
become somewhat grey owing to the increase of white hairs among 
the black. I have never seen a Serow with a beard like a goat, an 
animal which, on a large scale, it resembles. The legs are remarkable 
for the thickness and strength of their bones compared with the size 
of the animal, appearing to measure more below the knees than those 
of a Sambur deer. The feet are not big in proportion, but are small 
and compact, not splayed. The bones of the lees gave me the impres- 
sion of being extra hard and close-grained in texture. The iris of 
the eye is a very dark blue. 
In Siam the Serow inhabits steep and, in many cases, precipi- 
tous hills and low mountains, not, in my experience, exceeding 1500 
feet, and generally much lower. Personally [ have never seen or 
heard of it on any except those of limestone formation. It is not very 
markedly nocturnal in its habits, though said to be as much so as the 
Sambur deer, but moves about, to some small extent at all events, in
