WSSçptember. from the horns to the nofe fix inches and a half; from the horns to the rump four feet; from the. top of the back to the hoofs thirty-three inches; from the bending of the knees to the hoofc one foot ; the hoofs themfelves about an inch'. The dreffed ikin of a foetus,■ of which I took the meafure, was about two feet in length. A pair o bofch-bok’s horns, which I brought home with me, are ten inches long, and the bale of each five inches wide. But 011 the ikull of an animal of this fpecies, brought home by Profeffor T h u n b e r g , the horns were thirteen inches long, jj From the dimenfions of thefe parts, a con- clufion may be drawn with refpeft to thofe of the remainder, as well as with refpeft to the fize of the . animal in general. .. . . This fpecies of gazel is monogamous, or keeps in pairs. The female is, according to all accounts, diftinguiihed from the other fex in having no horns, in the loins being of a lighter colour, and in not having in thefe parts the- long hairs, and efpecially the white ones, which we are about to mention in the defcription of the male. • The herns of this are black, in fome meafure triangular, and at the fame time wreathed, fo that both the fides and angles have fomewhat of a -fpiral turn. At bottom they are rather rough, in. confequence. of a fet , of almoft innumerable wavy rings; which, however, are not elevated much above the furface. At top they are conical .and fharp-pointed, and in that part as fmooth as though they had been poliihed. In a pair I brought with me, the extreme points or tips are light-coloured and tranfparent. As to the pofition of the horns, they are almoft in the fame fame line‘or horizontal plane with the forehead, inclining T a little forftards, afid at the fame tithe, by means of thè W v i twift they make, receding from each other towards the middle, and making with this part a little bend backwards, fo that the tips point fomewhat forwards. Thé three angles or ridges;: that feparate the three fides juft mentioned, form a fpiral in the following manner : The foremoft is very much rounded and cylindrical, beginning inwards, and proceeding more and more forwards, till, coming fideways and a little outwards, it difappears in, and is-confounded ivith the fmooth conical tip. The fécond is a little raifed, and mòftly rounded off in the external part; but irtternally forms; as it were, a furrow, in conjunction with the foremoft. This latter angle or ridge, moreover, goes off at firft ftrait forwards from the forehead; and afterwards running fideways, outwards and backwards, at length joins the above-mentioned conical tip direflly at the back part. The third angle has a iharper edge, which, bé- ginnihg externally and at the back part, towards the middle o f thfe horn, runs backwards and inwards, and afterwards terminates inwards and fomewhat forwards; in the fmooth tip like the others. The teeth df this animal are like thofe of other gazels. It has nd fore teeth or incifores except in the lower jaw, where it has eight. Thefe are broader than the other teeth, be— ing fmall at the roots, and broad and fquared off at the top. Of the middle ones, which look towards each other,, the interior fides afe perpendicular ; but the exterior ones oblique, and all the reft have a proportional inclination, at the fame time dècreafing in fize ; fo that the o u te r -. moft, both to the right and the left, are the finalleft.
