ON THE DOMESTIC PIG OF 



supposes to be its still surviving representative, the ' Biindtner-Schwein,' as having a 

 short snout (see pp. 42, 45, 181-185). The classificatory value, however, of such a 

 peculiarity is much reduced by the results of such experiments as those of Nathusius 

 just referred to.

 Museum, adult ?. 



The skull from which this drawing was taken was that of a wild sow from the 

 Andaman Islands, procured for me by my friend J. Wood-Mason, F.G.S., of the 

 Calcutta Museum. It is about the same size as the two prehistoric British skulls, 

 Plate IV. Figs, i and 2, and as the 'Torfschwein' of Riitimeyer — resembling this latter 

 in the one important particular, that of its long fronto- parietal region, in which it 

 differs from the British skull (Fig. 2). It differs from all the pigs' skulls here figured 

 in the exaggeratedly disproportionate shortness of the malar border of its lacrymal 

 bone, which is, as in the newly-born European pig, little more than half the length of 

 the orbital border. In its convex frontal region we have, again, a character retained 

 in the adult Asiatic which is transitorily represented in the European pig. This
