SUS-STUDIES. 163 



(Banjermassiu) as the above described type-specimen of 

 Sus barbatus, has been procured by Dr. Scbwaner for our 

 collections; it is a stuffed specimen with its skull. The 

 less developed molars and the smaller beginning crista 

 (22 mm.) show that, although fullgrown, it is a younger 

 individual than the above described female-specimen. It 

 presents the above mentioned characteristics, viz. the very 

 developed beard, the peculiar thick tail-tuft, the small oval 

 ears, the elegant shape of the skull and the very elongate 

 bony palate, so that there is no reason to doubt its abso- 

 lute identity with Sus barbatus. The animal is darker colored, 

 however this may be because it is a male or it may prove 

 true the statement of Dr. S. Muller that the specimens 

 vary in color, from brownish yellow to blackish, in pro- 

 portion to the prevailing yellowish or blackish hairs. It 

 has the ornamental tufts on the posterior part of the nose 

 and the hairy border round the lachrymal glands, as well 

 as the elongated curled beard on the cheeks of the above 

 described female-specimen ; however the hairs or stiff bristles 

 are mostly black so that the animal looks quite black in 

 stead of reddish brown. The skull is a trifle smaller, as 

 the animal is somewhat younger as I observed above, 

 meanwhile the impression of the frontals is somewhat deeper 

 and the canines stronger developed. In our collection is 

 an other skull from the same collection, made by Dr. Schwaner 

 in Banjermassin ; it is the skull of a very old male, with 

 extraordinarily used molars so that the anterior premolars 

 in both jaws have vanished, with a still deeper impression 

 of the frontals than in the just now mentioned younger 

 raale-skull; the slenderness however of the skull and the 

 very great extent of the bony palate is highly striking. 

 The crest formed by the parietals is not more than 10 mm. 

 wide, so that we may conclude — taking in conside- 

 ration that in the very old male-skull there is not yet a 

 good developed crista — that at all events in Sus barbatus 

 a complete crista never occurs, perhaps only in extremely 

 old individuals.
