This animal is only known to naturalists by the name of _Grimm_, or the _Wild Goat of Grimmius_; and which, as we were not acquainted with the name it bears in its own country, we shall adopt. We find a figure of this animal in the German Ephemerides, which has been copied in the Academical Collection. Dr. Herman Grimmius was the first who mentioned this animal, and what he said of it has been copied by Ray, and afterwards by all the nomenclators. Although his description[X] is incomplete, he denotes two characters so remarkable, that we can have no doubt that the head of an animal of Senegal, given us by M. Adanson, belongs to the goat of Grimmius. The first is a very deep cavity under each eye, so deep, indeed, as to leave but a thin partition of bone between the cavities and the partition of their nose; the second is a tuft of hair standing upright on the top of the head. These are sufficient to distinguish the grimm from every other goat or gazelle. It resembles both, however, not only in the shape of its body, but even in its horns, which are annulated towards the base, and have longitudinal streaks like those of the gazelles; at the same time, they are very short, and bend backwards in a horizontal direction, like the small African goat before mentioned. Besides, from being much smaller, and from having short horns, we are almost led to conclude that this animal forms the shade between the goat and small antelopes. [X] This animal, on the back and neck, is of a dark ash colour, with a white belly, and is about a foot and a half in height; on the top of its head between the horns is a tuft of black hair, and between each eye and the nostrils, there is a cavity filled with a yellow humour, oily, and viscid, which has some resemblance to castor, and musk, and fills again upon the cavities being emptied. _Grimmius._ There is some reason to think, that the male grimm is alone furnished with horns; for the individual of which Dr. Grimmius has given the description and figure, had no horns: and the head which M. Adanson has given us was, on the contrary, ornamented with two, very short, and almost concealed by the hair, but yet sufficiently visible not to escape the notice of the observer; besides, we shall find, in the history of the chevrotains or small antelopes, that in the chevrotain of Guinea, the male only has horns, whence it is presumable, that it is the same with the grimm species, which in every respect approaches nearer the chevrotain than any other animal.
