Sus verrucosus, MiiU. cfc SchUg.^ and Allies. 535 



a skin of a wild hog from the same island, naming it " Sas 

 harbatus, var. palavensi's, Nehr." * 



Heude has since + made known the skull and teeth of his 

 Sus calamianensis from the Calamianes Isles, situated 

 between Mindoro and Palawan, the name having already- 

 been published in 1888 in the explanation of a plate showing 

 the upper and lower premolars. Heude refers his species 

 with a query to " S. longirostris, Nehr.," and states that 

 " S. ahcenobai-bus, Huet," belongs to the same group. 



In the same year Nehring \ corrects some errors in the 

 description, measurements, and figures of " S. ahcenobarbas^^ 

 (the skull named S. ahcenobai'bus is that of ^S^. Marchei, Huet, 

 and vice versa), which he is inclined to consider as identical 

 with his own S. barbatus var. palavensis. 



In the same place § short mention is made of the skull 

 of an adult male from Culion (Calamianes group), and the 

 opinion is expressed that >S'. calamianensis, Heude, is a second 

 variety of >S', barbatus, " 8. barbatus var. calamianensis ^ 

 Nehring." A detailed description is promised. 



The Natural History Museum received some years ago 

 from Mr. A. H. Everett four skulls of a wild pig from 

 Balabac Island (between Borneo and Palawan), one (B.M. 

 94.6.8.8) being from a male and three of females (B.M. 

 94.6.8.7—94.6.8.9—94.6.8.10). The male is almost com- 

 pletely adult, the two anterior thirds of the last molar 

 being in use. Of the female skulls, one (10) is immature, 

 the last molar being almost unworn ; skull 9 is of an old and 

 7 of a very old sow (molars worn to the sockets). 



I am of Nehring's opinion, that the pigs from Calamianes 

 and Palawan are somewhat dwarfy varieties of the Borneau 

 Sus barbatus, and the same holds good with regard to the 

 Balabac pig. In the table of cranial measurements given 

 below the reduced measurements of 8. barbatus balabacensis 

 are placed side by side with the same of S. barb, palavensis ; 

 these last are calculated from the absolute measurements 

 given by Nehring 1| ; for comparison liave been added the 

 measurements of a male and female skull of S. barbatus, 

 reduced as above from the tables in Nehring's paper ^.
