 (Abstract.) 



This memoir will be printed in the Society's Transactions in full. 



The following specimens were exhibited at the Meeting : — 1. 

 Skidl of 8. scrofa, var. domesticus, from a late Celtic interment. 

 2. Skulls of S. scrofa, var. ferus, from alluvium near Oxford and 

 from G-ermany. 3. Skull of S. andamcmensis, forwarded to the 

 Author by J. "Wood Mason. 4. Skull of S. cristatus, lent by Sir 

 Walter Elliot, K.C.S.I. 5. Skull of S. larhatus, wrongfully 

 named S.verrucosus, and needlessly Euhys harhatus in some mam- 

 malogical catalogues. 



TJpon these and other data the author bases the subjoined con-

 exemplified by the specimens from the interment referred to, ap- 

 pears to resemble B. scrofa, vox. ferus, rather than 8. cristatus or the 

 domestic variety, 8. indicus. 



2. On the other hand, S. cristatus, the Indian wild hog, appears 

 to him, whilst being readily and always distinguishable from >S'. 

 scrofa, var. ferus, to dijffer from it mainly by the retention perma-

 porarily represented in the European wild species. The third 

 molars of the male 8. cristatus varied, however, concomitantly 

 with its canines, and showed a much larger development of their 

 posterior lobe than either 8. scrofa, var. ferus, or the females of 

 their own species. The rearmost lobe, however, of the posterior
