48 OYLDENSTOLPE. ON A COLLECTION OF MAMMALS MADE IN EASTERN AND CENTRAL BORNEO. 



Four species of wild Pigs are stated to occur in Borneo viz. Sus barbatus barbatus 

 S. Mull., Sus barbatus gargantua Miller, Sus vittatus vittalus Mull. & Schleg. and 

 Sus celebensis bomeoensis F. Major. The first named form seems to be most common 

 and is generally distributed throughout the whole Island. Of the latter form there 

 is up to the present ti me only a single authentic specimen shot by Wallace and 

 kept in the Brit. Mus. Natural History. 



The specimen in the present collection is unfortunately not fully adult, and it 

 is then rather difficult to state to which form it belongs. The skull is rather low, 

 thus resembling that of S. celebensis bomeoensis which, however, is a smaller animal. 

 But in colour the present specimen resembles S. barbatus to which species I have 

 provisionally referred it. 



Skull measurements: Greatest length of skull: 342,3; condylobasal length of 

 skull: 3 10,o; basicranial length of skull: 296,4; zygomatic width: 117,o; greatest width 

 of braincase: 70.2; occipitonasal length: 332,6; length of nasals mesially: 159,o; 

 breadth of combined nasals at posterior extremity of intermaxillare: 29,2; least inter- 

 orbital width: 56, 1; least postorbital width: 70.2; median palatal length: 227,5; 

 breadth of palate between inner edge of m 2 : 24,c mm.

Mr. Lumholtz has collected six specimens of this small Muntjac, the type of 

 which was obtained at Pleihari in Southeastern Borneo. In M. m. 'pleiharicus the 

 antler pedicles are very short, considerably shorter than in any other known form. 

 The general colour is nearest »Amber brown» (Ridgway pl. 3), darker and more 

 brown (»mars brown») along the dorsal line, which is somewhat grizzled with russet 

 brown; ears brownish on the outside, whitish on the inside. The bases of the ears 

 similar to the adjacent parts of the head. Chin, throat, under parts of the body, 

 inner sides of legs continued down to the ankles of the hindlegs whitish, most 

 conspicuous on the latter part. Outer side of legs like the sides of the body. Tail 

 whitish with a narrow dorsal stripe of dark brown mixed with ochraceous. 



Among the present series there is also quite a young specimen, showing a 

 somewhat differing colouration. On the back there are six longitudinal rows of 

 whitish spöts most conspicuous on the two middle rows where the spöts are larger 

 and well-defined. The posterior parts of the lower surface of the body dirty white,
