skull 1362 d, celebensis generally, and the Bornean form of 

 verrucosus * have still more prominent zygomatic arches than 

 the skull from Amboina with which Lydekker compared the 

 fossil. 



3. Sus verrucosus ceramicus^ Gray. 



A skull of an adult male (B. M. 112 d) from Ceram, col- 

 lected by A, E,. Wallace. As mentioned above. Gray 

 originally f considered this skull — rightly, in my opinion — 

 to be a variety of S. verrucosus ; in the ' Hand-list ' it figures 

 with the Sus verrucosus of Java as " Dasychcerus verru- 

 cosus " \. 



On account of the slenderness of the snout, this skull 

 presents a very elegant appearance. In length it is equal to 

 weaker specimens of the Javan form ; in relative breadth of 

 the zygomatic arches (see table of measurements no. 5) it is 

 the narrowest of all the forms of verrucosus which have come 

 under my notice; in relative breadth of the front (nos. 6, 7) 

 it ranges with the narrowest specimens of S. verrucosus. In 

 relative height (nos. 15, 16) this skull is surpassed by all the 

 members of the group with the exception of mindanensis. 

 The nasal region is very narrow as compared with all the 

 other skulls of the verrucosus type. The crest above the 

 canine is weak — short, low, and narrow. 



Of the last molar of this specimen Rolleston has stated § 

 that it is comparatively simple as compared with other 

 specimens of S. verrucosus. This remark holds good with 

 regard to all the molars and premolars of ceramicus ; thus it 

 approaches ce?eJens2s and amboinensis ; in the elongation of 

 m. 3 it, however, ranges with verrucosus from Java. 



In a paper by Jentink || mention is made of a Sus ceram- 

 ensis, Rosenberg (Malayisch. Archipel. 1878, p. 362j, said 

 to occur in enormous quantities in Ceram and on all the 

 islands from Ceram-laut to Tijoor. Besides, there are in 

 the Leyden Museum skins from Tidore, Ternate, and 

 Waaigeou, collected by Dr. Bernstein ; and Jentink is of 

 opinion that all these are one and the same species, and 

 identical with Sus niger, Finsch ^, from New Guinea.
