174 SUS-STUDIES. 



observe that according to Dr. Dvbowsky — as Dr. Nehring 

 wrote — his specimens showed »zwei warzenahnliche Haut- 

 falten im Gesicht", now harhatus practically has two pairs 

 of tufts of stiff elongated bristly hairs, which might be 

 called perhaps » warzenahnliche Hautfalten"; but such tufts 

 never can be compared with the enormously developed 

 warts or protubera7ices on the face of verrucosus. 



All our specimens are from Java and never has any 

 naturalist procured a verrucosus from other islands; it is 

 therefore very remarkable that according to Dr. Forsyth 

 Major, I. c. p. 534, there is in the British Museum the 

 skull of an old male from Borneo, collected by j\ir. A. R. 

 Wallace; he describes it as belonging to an individual of 

 a new subspecies, Sus verrucosus borneensis. That is all what 

 is known about the animal. 



In the «Verhandelingen" has been described Sus vittatus, 

 based upon specimens collected by the members of the 

 » Natuurkundige commissie", in Sumatra and Java. Now 

 in December 1904 Mr. Gerrit S. Miller Jr. from the 

 Washington Museum was studying here during a fortnight ; 

 he suggested that the specimens described as Sus vittatus 

 might turn out by close inspection to be a mixture of two 

 distinct species, the one from Sumatra, the other from Java; 

 and indeed by looking through our material it soon appeared 

 that Miller was quite right in his suggestion. There are, 

 as well in the skulls as in the external appearance, diffe- 

 rences constant for the animals procured from each of the 

 two islands. The figures of the animal as well as those 

 of the skull evidently have been drawn by Prof. Schlegel 

 under the impression of the specifical uniformity of the 

 pigs of both localities, so that the description is appliable 

 to both and as to a certain degree also the figures, there- 

 fore it now hardly can be made out what Schlegel's typical 

 specimen really has been. Under these circumstances we 

 had to solve the question by letting the old name to one 

 of the species and give to the other a new name ; after all
