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

 skulls of female exotic Pigs are very rare iu collections. 



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

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

 ■with a well-defined wide ridge behind in 716 o, 716 c, and 716 Ar. 

 It is less marked in the others, in difierent 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 c, 716 w, 

 716 m, 716 (/, 716 .r. 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 all the skuUs differ from the skulls of S. verru- 

 cosus in the flatness of the zj-gomatic arch, compared "svith the thick 

 swollen form of the zygoma in all 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. Concamty on the cheeks of the skull in front of the orbit shalloio 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.

15C*1 a. A skull of a young animal, very like the one figured 

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

 Babirussa/' from Mr. Wallace's collection. It is certainly not a 

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

 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. SkiiU ■svith the last grinder being developed (on one side 

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

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

 ing iu 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 b. A rather larger skull, also developing the last molar, and
