collected is hardly sufficient to demonstrate this, the circumstance that 

 one of the three known adult skulls of Sus oi is longer than any 

 among twentij^-seven of Sus harhatus strongly suggests that such is 

 the fact. 



The seven skins collected by Doctor Abbott show no very striking 

 variations other than those due to age. The youngest specimen, a 

 male from Pulo Kundur, with head and body 860 mm. in length (No. 

 122930), is a uniform blackish brown throughout, the skin fairly well 

 covered by hair, except about ears and along median portion of under- 

 parts, most of the hairs tipped with dull ochraceous butf, but this 

 color quite inconspicuous except along middle of back and neck, where, 

 particularly on neck, it forms almost a light median stripe. The hairs 

 along ridge of back and neck are lengthened to form a slight mane. 

 Face uniformly covered with short, soft, unmodified blackish hairs, 

 which scarcely conceal the skin. Rostral protuberances distinct, 

 ahiiost naked, about the size of small peas. The next stage is repre- 

 sented b}^ the four skins from Banka — a female (No. 1247(51) 1,090 mm. 

 in length (head and body), and three males (No. 124716, No. 124760, 

 and No. 124908), ranging from 1,100 to 1,230 mm. In each of these 

 the body is less thickly haired than in No. 122930, though sufiiciently 

 clothed to give the animal a blackish appearance. Light tips to the 

 hairs occur very generally in three of the skins, but in the fourth they 

 are practically confined to the short and inconspicuous mane. In the 

 female and two of the males the beard is well developed, causing the 

 head to appear much more hairy than the body. It is further made 

 conspicuous by the strong contrast of its light color with the blackish 

 body. In the third male (No. 124716) it is partly grown. In all four 

 the bristles hide the rostral protuberances, which, however, are readily 

 appreciable to the touch. Muzzle and forehead blackish, in marked 

 contrast with light beard. The female from Pulo Kundur (No. 122869), 

 with head and bod}^ 1,330 mm. in length, though essentiallj^ like the 

 smaller individuals, appears lighter in color on account of the more 

 sparse coat. There is a thin though noticeable mane along neck and 

 anterior half of back. Finally, in the type, a young adult male (head 

 and body 1,575 mm.), the general effect is that of a naked, 3'^ellowish 

 animal, with the body rather thickl}^ sprinkled with blackish bristles, 

 the light tips of which are scarcel}^ noticeable on account of their close 

 similarity to the color of the skin. The body of this animal is much 

 more scantily haired than in either of the two adults of Sus harhatus 

 that I have examined. (See Plates LI and Lll.) Only on the cheeks, 

 face, and throat is the hairy covering complete.
