270 PROF. ROLLESTON ON THE DOMESTIC PIG 



Skull of young female, Sus cristatus. British Museum, 716 to. " Terai, Nepal ; Dr. Oldham." 



Height of lacrymal 11 in. ; malar border 075 in. 



Skull of adult female, Sus cristatus, 716 n. British Museum. "India; Professor Oldham." 



Height of lacrymal - l in.; malar border 07 in. 



Skull of young female, Sus cristatus, about 9 months old. British Museum, 716 q. " Nepal ; B. H. 

 Hodgson." 



Height of lacrymal - 9 in. ; malar border 0'75 in. 



Indian pig, Sus cristatus, British Museum, 7l6g, under 5 months of age, very convex frontals, slightly 

 tumid lacrymo-frontal ridges. 



Height of lacrymals 05 in. ; malar border 0*25 in. 



Indian pig, Sus cristatus, British Museum, 716 v. "Nearly adult female, Nilgherris." 



Height of lacrymal 095 in. ; malar border 06 in. 



Young male of Sus indicus; in collection of British Museum, not catalogued; with 3rd molar just 

 coming into use — that is to say, about 18 months old. 



Height of lacrymal 0-9 in. ; malar border 0*9 in. 



Skull of Indian Wild Hog, Sus cristatus, no. 3251 a, Boyal College of Surgeons of England. This is 

 the skull of an adult male probably, the complexity of the posterior lobe of the 3rd molars being very 

 o-reat. The naso-frontal suture resembles that of Sus scrofa rather than that of Sus cristatus. The 

 lacrymo-frontal ridge is very largely developed. 



Height of lacrymal Ol in. ; malar border T25 in. 



Skull of Indian Wild Hog, Sus cristatus, no. 3251 b, R. C. S. England. 



Skull of Indian Wild Hog, Sus cristatus, no. 3251 c. R. C. S.England. 



Height of lacrymal Ol in., malar border 095 in., in both. 



These two skulls were probably from the same district as no. 3251 a ; but they differ from it, and agree 

 with all the other specimens of Sus cristatus, in having the height and the malar length of the lacrymal 

 subequal. 



Skull of Wild Sow from Andaman Islands, Sus andamanensis , no. 151-1 b, Oxford University Museum. 



Height of lacrymal 17 mm. ; malar border 8 mm. : adult. 



Skull of Sus vittatus from Amboyna. Alfred Russel Wallace, Esq. British Museum, " 1362 c." 

 An adult male with a nearly straight naso-frontal suture, and a convex fronto-parietal region. 



Height of lacrymal 0"55 in. ; malar border 0-8 in. 



Sus vittatus. British Museum, 1362/. "Skull of animal developing the hinder molar." The 

 lacrymo-frontal ridges are convex, the frontal region is flat, the naso-frontal suture, however, is straight, 

 as in S. cristatus. 



Height ol* lacrymal 1-05 in. ; malar border 0-6 in. 



II. Sus scrofa, yav.ferus, and its allies. 



" Sus libycus." British Museum, 713 a. " Hab. Asia Minor, Xanthus (Sir Charles Felloives). The 

 skull is very distinct from all the skulls of the Wild Boars from Germany in the British Museum." The 

 animal was just about 18 months old : its interectorbital region is still convex; but it has no very marked 

 lacrymo-frontal ridge ; its naso-frontal suture is convex backwards, as in Sus scrofa, var. ferus ; its nasals 

 are 8 in. long, as against 14=§ of total skull-length ; and the height of the lacrymal is less than its 

 inferior length. Here it resembles Sus scrofa rather than Sus cristatus. 



Height of lacrvmal 1 in. ; malar border 0-15 in.
