The skull of the Saleyer seen from above shows not the 

 elegant shape of barbatus and as much not that of verrucosus 

 but more ao intermediate stage. The animal must be a 

 very strong build one, for the skull although not large is 

 very broad and thick-bony; in this male-skull the osseous 

 crest above the alveolus of the upper canine is relatively 

 as well as absolutely much stouter developed and more 

 thickened behind than in the larger species ; the canines 

 are strong and very curved. Although the molars are feebly 

 used and therefore the skull not very adult, the distance 

 between the parietalia (later crista) is only 20 mm. The 

 profile-line of this fullgrown skull is feebly concavely curved, 

 froutalia and uasalia very rough. Bony palate much more 

 protruded beyond the hind-most molar than in celebensis. 

 Side of the lower jaw in the middle somewhat swollen. 



There is a hypothesis generally accepted by Zoologists 

 that there have been land-connections between the large 

 Islands of the western part of the East Indian Archipelago 

 and the Indian continent; they want such land-bridges to 

 explicate the fauna of these Islands. This hypothesis may 

 be based upon geological grounds, it however is a fact that 

 a lot of animals now living in these islands iiave no repre- 

 sentatives on the Indian continent, f. i. what Paradoxurus- 

 species, what ^?ioa-species, what Babirussa-S]^ecïes have 

 walked over the laud-bridge to Celebes? Paradoxurus Mus- 

 schenbroekii, Anoa depressicornis and Babirussa alfurus have 

 at present no representatives on the continent ! The defenders 

 of the land-bridge-hypothesis however will tell me that in 

 the darkness of past geological ages a Paradoxurus^ an 

 ^woa-like animal, a Pig walked over the temporary bridge; 

 that these animals lived for centuries isolated on Celebes and 

 have given rise to offsprings quite different from the original 

 forms, — developed by the stuggle for life and existence? 

 Not very likely, as there are on Celebes nor have existed 

 in foregoing ages, as far as we know, large Paradoxurus-, 

 or Anoa-, or Pig-e^img mammals or other carnivorous ani-
