258 CLASS MAMMALIA. 



The Cephalophine Group. 



We place, among others, in this group, the animals which 

 have been noticed by authors under the name of Grimmea, 

 varying very considerably in stature, but all distinguishable 

 by a tuft of hair rising from the forehead, and more or less 

 spread between the horns ; by a pouch or sack opening be- 

 tween the orbits and the nostrils, in some forming a black 

 slit in the shape of a segment of a circle ending near the 

 nostrils, in others by a puncture near the corner of the 

 mouth, and seemingly appropriated to a different purpose 

 in the animal economy, than the usual lachrymary sinus. 

 The horns of all are small, straight, or nearly so, reclining, 

 placed high on the forehead, black, with wrinkles or annuli ; 

 the muzzle is rather developed and black, and several have 

 the forehead entirely covered with long fulvous hair, parting 

 to the right and left from the centre. With the exception 

 of one, they want no brushes, the pasterns are short, and 

 mostly of a dark colour, passing in a streak upwards to be- 

 yond the knees ; the tail is short and tufted with long black 

 hairs ; the females are without horns, and have two or four 

 mammas. The group extends over South Africa, from 

 Senegal to the Cape of Good Hope. It is probable that the 

 whole is possessed of nearly similar manners ; residing in 

 bushes and low covers, standing up on the hind-legs to 

 look out for danger, even leaping into the air to overlook 

 obstructing vegetation, and then running into concealment 

 from one bush to another. These manners, and the strong 

 family resemblance maintained through them all, account 

 for the difference of stature assigned to species under the 

 same name, and the vain endeavours to make them agree.

* Silvicultrix appears to be a wrong translation of Bush Goat. 

 The Swedish Zoologist has no doubt mistaken the meaning of bush, 

 and considered it synonymous with forest; Desmarets justly applies 

 the term Buisson,
