Peculiar features of the Mindanao skull are to be found in 

 the considerable length of the snout : — 



M. L. 



Eelat. length of intermaxilla at alveolar border 26-4 247 . 23-8 



The nasals of the ^Mindanao skull are very narrow in the 

 middle of their length ; but the whole of the nasal region 

 still remains remarkably broad, on account of the overlapping 

 of the intermaxillte on the upper surface of the nasal region. 



On placing side by side the Mindanao skull with those of 

 the Celebes form and. the verrucosus proper from Java, there 

 can remain no doubt that the first differs as much from the 

 second as this latter does from the third. So that if the 

 Celebes Wild Boar is to be maintained as a distinct species, 

 it would be only consistent to raise the Mindanao form as 

 well to specific rank. Of course, it results from the fore- 

 going remarks that the Luzon form holds in most respects an 

 intermediate position betvv^een mindanensis and celehensis 

 (contrary to wiiat might have been expected from the geo- 

 graphical position of its habitat). But, on the other hand, 

 the Bornean form of verrucosus^ to be considered hereafter, 

 intervenes betu'een celehensis and verrucosus of Java, by the 

 considerable breadth between the zygomatic arches and by 

 the relative shortness of the last molar. 



Lastly, to connect all these forms still closer together, 

 almost all the characters by which philippensis and minda- 

 nensis differ from celehensis are such as approach the first 

 two to the Javan verrucosus. 



Under these circumstances I cannot see my way to esta- 

 blishing a new species for the Mindanao form, and still less 

 can I range it as a variety under a species 8. celehensis. But 

 I prefer to treat it as a subspecies of S. verrucosus, Miill. & 

 tSchleg., on equal rank with S. verrucosus celehensis^ S. verru- 

 cosus jjhilippensis, Nehr., and the other forms with which I 

 have still to deal. S. verrucosus of Java becomes the type 

 of the species on no other than priority grounds. 



Heude has of late described and figured no less than seven 

 new species of Sus from the Philippines : L Sus effrenus ; 

 2. S.Jrenatus ; 3, S. microtis ; 4. S. cehijrons ; 5. S. niinutus ; 

 6. S. arietinus ; 7. S. calamianensis *. Four of these, viz. 

 1, 2, 3, 6, are from the Island of Luzon; the first-named 

 three from one locality, Jala-Jala, " une langue de terre de 

 huit kilometres de cot^ ; elle termine la grande p(?ninsule 

 dependant de la province de Moron, dans le lac de Bay " f.
