114 THE PROBOSCIS-MONKEY 



on tbe »versant occidental de la chaiue separant la vallee 

 du Mekong de celle du fleuve Bleu dans les forêts" ; it has 

 a nose exactly like Roxéllana •) and like that species very 

 short nasal bones. It seems that Rh. Bieti was an unknown 

 species to Dr. Brandes. Further, the name nasicus is not 

 correct, as another specific title larvatus was bestowed upon 

 the Borneo-animal twenty years before, by its first describer ; 

 therefore the correct orthography should be : Nasalis larvatus 

 from Borneo, Nasalis Roxellana from the continent and Na- 

 salis Bieti too from the continent, if Dr. Brandes' hypothesis 

 could be accepted. The three species however cannot by 

 any means be united in one genus, as the Bornean Pro- 

 hoscis-monhey differs from all other Semnopitheci by its 

 having nasal bones much longer than in any other Semno- 

 pithecusl In the youngest skull of our Proboscis-monkey- 

 series the nasalia are a good deal longer than in the figures 

 of the skulls of very old specimens of Roxellana and Bieti, 

 figured in Milne Edwards' papers; in the Bornean-species 

 therefore the »Naseubeine" are the inverse of »schwach 

 ausgebildet", as Dr. Brandes exhibited as base of his 

 hypothesis; so that till now the Bornean-Monkey stands 

 alone in the genus Nasalis, meanwhile the other two are 

 to be united under the generic title Rhinopithecus.

1) Roxellana is the correct specific title as given by Milne Edwards in 

 the first description of the animal (Comptes rendus des seances de l'Académie 

 des sciences, Paris, 1870, p. 341). W. L. and P. L. Sclater relate (the Geo- 

 graphy of Mammals, 1899, p. 25) that this monkey has been named roxel- 

 lanae from its conspicuous turned-up nose ! ! The name certainly has nothing 

 to do with the animals-nose, as Hoxellana evidently means russianl, Roxolania 

 or Roxolaui being an old expression for the later intruders or Sclavonians in 

 Russia. (Ph. J. von Strahlenberg, das nord- und östliche Theil von Europa 

 und Asia, 1730, p. 169).
