front of the orbit, perhaps the character of the female sex. The 

 skulls of female -exotic Pigs are very rare in collections. 



This series of skulls differ in the depth of the concaTity on the 

 hittder part of the cheeks in front of the orbit. It is very deep, and 

 with a weU-defined wide ridge behind in 716 o, 716 v, and 716 'h. 

 It is less marked in the others, in diiferent degrees of distinctness 

 and depth. 



In the skulls of the younger animals the concavity is very shallow 

 behind, and gradually shelving off to the orbit, as in 716 e, 716 w, 

 716 m, 716 q, 716 X. It is one of these skulls (716 w) that Mr. 

 Blyth marked as like his type of S. bengalensis. 



The skull of this species is like that of Sus verrucosus from the 

 Malay Islands ; but aU the skulls differ from the skulls of S. verru- 

 cosus in the flatness of the zygomatic arch, compared with the thick 

 swollen form of the zygoma in aU the skulls of that species. The 

 sides of the lower jaw are convex and swollen, but not so much so 

 as the lower jaw of S. verrucosus. 



b. Concavity on the^cheeks of the shull in front of the orbit shallow behind, 

 only separated from the orbit by a narrow ridge. 



6. Sus timorensis. B.M. 



Yellowish or blackish brown, generally with a white streak from 

 the nose to the angle of the jaw. Ears moderate, nakedish ; fur 

 with scattered bristles, maned. " Head without any warts." Skull 

 (young) — the concavity in front of the orbit shallow behind, and 

 only separated from the orbit by a slight ridge.

1501 a. A skull of a young animal, very like the one figured 

 by MiiUer (Yerhand. t. 32. f. 2, 3) ; it is marked " young female 

 Bahirussa," from Mr. Wallace's collection. It is certainly not a 

 Babirussa, having six upper cutting-teeth and short intermaxiUaries, 

 but is more probably a young female of the preceding. It has the 

 concavity in front of the orbit shallow, and only separated from the 

 orbit by a narrow ridge. 



1501 c. SknU with the last grinder being developed (on one side 

 only), perhaps young male ? Inscribed " a WUd Pig, Makassar." 

 Length 10|, height at occiput 6 inches. Nose broad behind, taper- 

 ing in front from orbit ; concavity in front of orbit large, not deep, 

 and extending close up to the. edge of the cavity ; the hinder suture 

 of the parietal bone is produced and angular behind. 



1501 6. A rather larger skuU, also developing the last molar, and
