540 ON THE DOMESTIC PIG OF 



spoken of a real male Sus harhatns as having a skull with a straight 

 profile ; Muller and Schlegel figured a female skull, whereas Mr. 

 Blyth's, I am sure, was a male's. As regards the contraction of 

 the vertex, which shows Mr. Blyth's skull to have been a male's, 

 this is sometimes exceeded by the old and strongly muscular Indian 

 wild hog, such as Sir Walter Elliot's No. 71 (for history of which 

 see p. S?>3)i where it is only 8", whilst in the skull No. 72 it is 

 i-S'', showing an oscillation, owing to the varying action of the 

 temporal muscles, which entirely deprives it of any morphological 

 value ; and the measurements of the molars, finally, assure me that 

 there is no need to add the words ' und wahrscheinlich auch Ceylon' 

 to the word ' Borneo' as the ' Vaterland' of Sus barbatus, as Fitzinger 

 has done, I. c. p. 393. Miiller and Schlegel, p. 179, give Borneo, 

 if I rightly read their words, as the ' habitat ' of this well-marked 

 species. 



Secondly, of Sus verrucosus. The soft and perishable parts of 

 Sms verrucosus are even more interesting and of greater importance 

 than the bones ; for they show us that wild pigs do have appendages 

 — warts, to wit, covered with long bristles, and attached to the 

 corners of the lower jaw, like those of the Irish greyhound pig, 

 once so plentiful in Gal way ; and they thus do away with one of 

 the objections to Mr. Darwnn's views, stated fairly (by himself) in 

 the work on ' Animals and Plants under Domestication,' i. p. 79, ed. 

 1875. If it is a profitable thing to lay Muller and Schlegel's figure 

 of Sus verrucosus (tab. 28. I. c.) alongside of Richardson's figure of 

 the ' old Irish greyhound pig ' (/. c. p. 49 ; Darwin, I. c. p. 79), 

 it is profitable also to read the Dutch letterpress^ of the two former 

 authors, from which we learn, when helped by the translation given 

 by Fitzinger, that the young of Sus verrucosus are never striped, and 

 hereby have it suggested to us how it may be that so many of our 

 domestic breeds never have their young striped — none, in fact, ex- 

 cept the Westphalian and the Turkish. Riitimeyer {I. c. p. 187) 

 has suggested that the so-called ' Berkshire breed ' of domestic pigs 

 may have its parent stock in Siis celebensis, as figured by Schlegel 



* The words of the two Dutch naturalists are, 'Verhandl.' p. 177: ' De deer 

 jonge voorwerpen dezer sort zijn niet gestreept, en onderschieden zich daardoor van 

 de jongen van Sus vit'tatus en van de meeste, ja, misschien van alia overige soorten.' 

 It is much to be regretted that Dr. Gray did not enter a note of this most im- 

 portant fact in his papers above referred to, in which the * Verhandiungen ' are 

 often cited.
