shallower behind, shelving off to the orbit, and only separated from 

 the orbit by a narrow ridge ; in the male the sheaths of the upper 

 canines with a well-marked ridge ; the concavity in front of the 

 orbit very wide ; in the female the concavity narrower, and sheaths 

 of the canines not developed.

Hub. Andaman Islands. B.M. 



Living in the Gardens of the Society. Also a hybrid between 

 the female Andaman Pig and the male Wild Pig from Dampier 

 Straits. 



A skull of an adult male in the British Museum, without lower jaw 

 (no. 1497 «). The four front upper cutting-teeth very large, entire, 

 square ; the hinder lateral one very small, early deciduous. Lower 

 cutting-teeth six, subequal, close together ; upper canines very large, 

 recurved, with a deep central ridge on the upper edge ; concavity 

 in front of the orbits very wide and deep ; sheath produced, with a 

 well-marked longitudinal crest on the upper reflexed edges. 



A complete skull of an adult female (no. 1497 b), very similar to 

 preceding, but concavity in front of the orbit narrower behind. 

 Upper canine small, compressed, without any developed sheath ; 

 no ridge above its root. Lower canines very large, subtrigonal, 

 with the first two rooted ; premolar on the hinder part of its base 

 separated a short distance from the second premolar. Upper cutting- 

 teeth three, the first very large ; the second on the right side, and 

 both the hinder one have fallen out, and the cavity left is filled 



up. 



The skull of this species is more nearly allied to the Babirussa 

 than any others of the Pigs {Svs), the front of the canines being 

 rather more produced than in other species, but not nearly so mucii 

 so as in Babirussa ; and the two hinder upper cutting-teeth are 

 very small and often deciduous. In the skull of the adult male, for 

 example, they are very small, but the pits they filled are present ; 

 in the adult female, they and the pits they filled are entirely oblite- 

 rated. By a curious coincidence the second upper cutting-teeth on 

 the right side of the jaws of the skulls of both the male and female 

 animals are wanting, and the pits they filled are obhteratcd ; but 

 this may be only an accidental circumstance, as the tooth on the 

 other side is well developed. 



8. Sus SCROFA. 



Ears large, densely hairy. Fur blackish brown, densely bristly. 

 "Wart under the eye small. Skull elongate, slender ; the concavity 

 on the cheeks in front of the orbits wide, shallow behind, shelving 

 towards, and only separated from the orbit by a narrow ridge.
