probably a young male. A "Wild Pig, Ternate, from Mr. Wallace's 

 collection. Length 12|, height 5| inches. It is very similar to the 

 above in all particulars, particularly in the shallowness of the con- 

 cavity in front of the orbits, and in the crest-like form of the ridge 

 behind the base of the sheath of the upper canines ; hinder suture 

 of the parietal produced and rounded behind. 



The shallowness of the concavity on the cheeks of these specimens 

 may depend on the youth of the animal, as it is to be found in the 

 skull of the young Sus indicus. It is not always a character of youth, 

 as it is found shallow and shelving off behind in the skull of the very 

 old Sus andamanensis and S. scrofa. 



There is the skin and skeleton (1501 d) of a " Wild Pig from 

 Dampier Straits, in the Eastern archipelago," that was brought to 

 the Museum by Mr. Swinhoe. It does not appear to differ from 

 /S. timorensis of S. Midler ; and the skull is very like the skull 

 from Ternate (1501 h). A specimen was living in the Society's 

 Gardens. Mr. Bartlett thinks that the latter is " a domestic Pig 

 running wild, because he has seen two specimens of them, both of 

 which had white markings about the legs in a very irregular manner 

 and other characters of the domestic Pig." 



7. Sus andamanensis. (Andaman Pig.) B.M. 



The concavity of the cheeks in front of the orbit deeply concave, 

 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. i^^ 4 //^/ J.^.tA^>^^rf< P^y

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



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 11 



large, recurved, with a deep central ridge on the upper edge ; con- I 



cavity 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 ; 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 ones have fallen out, and the cavity left is filled up.
