160 SUS-STUDIES. 



Sus harbatus »völlig identisch." This step he has to take 

 over the » warzencihnliche Hautfalteri\ which Grabowsky 

 recollected having observed in the animal in question; 

 now, Hautfalten hardly can be called protuberances^ the 

 more Grabowsky gave his informations from memoi'y ! I 

 think it therefore consequent to cancel the specific-title 

 lonyirostris until a skin with skull may prove that we are 

 wrong in our conclusion. 



There has been figured by Nehring (Die Rassen des 

 Schweines, p. 20, fig. 4) a Pig-skull, from the Zool. 

 Sammlung d. Landwirthsch. Hochschule in Berlin, as »Schadel 

 eines manulichen Bartschweines aus Borneo, ^/^ nat. Gr." 

 It measures 562 mm. It therefore is a good deal larger 

 than the largest known 6ariaf?^s-skull; moreover if compared 

 with a true barhatus-&k\i\\^ f. i. with Nehring's figure of 

 longirostris = barbatus on p. 22, there are such great diffe- 

 rences in the shape that it is very apparently that Nehring 

 has here figured a skull certainly not belonging to barbatus 

 nor to another known species. It is perhaps a skull of 

 an unknown very large Borneo-pig? As Nehring took this 

 large skull as that of a barbatus-si^ecimen, it is evident 

 and explicable why he was forced to describe his true 

 barbatus-sk\i\\ as a new species, longirostris! 



As there is in the Leyden Museum a rather large col- 

 lection of Pig-skulls from the Malayan Archipelago and 

 as these bony parts never have been thoroughly studied, 

 and therefore not always bestowed with the correct specific 

 title, I have reviewed our collection by the broad light 

 that we owe to the investigations by Nehring, Spillner, 

 Forsyth Major, von Nathusius, Rütimeyer and others. This 

 study finally will throw much light over the question 

 whether Sus oi, our Nangoei^ may be admitted as a good 

 species. 



The following study will interest Zoologists the more 

 as the type-specimens of barbatus, verrucosus, vittatus and 

 celehensis are in our collection, having been described by
