broader towards the sides of the upperlip ; for the rest 

 the head is adorned with a mixtum of reddish brown, black 

 or black- tipped reddish' brown thickened bristles, especially 

 of extraordinary thickness and very elongated and curled 

 on the cheeks, short on the forehead, forming on both 

 sides of posterior part of muzzle a tuft of stiff elongated 

 bristly hairs, another party of such although shorter hairs 

 is to be found anterior to each eye (lachrymal gland) ^), 

 middle of back with rather elongated reddish brown hairs, 

 these hairs grow shorter towards the base of the tail and 

 the sides of the body, they are on the latter parts inter- 

 mixed with black tipped hairs, meanwhile most of the 

 hairs on the sides and extremities are black throughout; 

 the thick tuft of the tail is black also. This tail-tuft is 

 quite unlike from all other tail-endings in the large Pig- 

 species, it reminds the tail-tuft of some Col obus -species. 

 The very developed beard and this peculiar tail-tuft com- 

 bined with the small oval ears and flesh-colored nose ^) 

 characterize this species. 



The skull has been figured in the s. Verhandelingen", 

 Tab. 31, figs. 4 and 5; it belongs to a complete skeleton. 

 It is very elongated and surprisingly small across the 

 zygomatics; the malar and maxilla bones describe a sloping 

 line from behind towards the infraorbital foramen, so that 

 the skull makes a very slender and elegant impression ; 

 upperpart of skull slightly concave by an impression of 

 the froutals; the parietals form a beginning crest of 12 

 mm. ; the bony palate extends far beyond the last molar 

 (45 mm.), ending in a deep sharply pointed V. The elegant 

 shape, together with the very elongate bony palate, charac- 

 terizes the skull of this species.

1) These bristles cannot be compared with the large warts or protuberances 

 of Sus verrucosus, as they merely erect directly from the skin, without a 

 trace of wartlike base; moreover they do not occupy the same parts on the 

 head in the two species. 



2) Evident in fresh specimens, not or badly to observe in dried skins.
