200 ON THE NEW-GUINEA MAMMALS. 



104. Dendrolagus ursinus Muller. 



The type-specimens in the Leyden-Museum are from South 

 Dutch New-Guinea, Bay Lobo, collected by Muller and 

 Macklot (1828), others in that collection are from N. 

 D, N. G., Doreh, collected by von Rosenberg. In the 

 British-Museum is an adult female from Skroe, Maclure 

 Inlet, W. N. G., from Forbes' collections. The Genoa- 

 Museum received two specimens from the Arfak Mountains 

 by Mr. Bruyn. 



105. Dendrolagus inustus Muller. 



Like ursinus this species has been found at the Lobo- 

 Bay (type-specimens from Muller and Macklot, 1828), at 

 Andai (von Rosenberg) and at Doreh (Hoedt); besides 

 specimens from these localities the Leyden-Museum pos- 

 sesses an adult male from Diard's N. G. collections and 

 a young individual from the Arfak Mountains. Wallace 

 has collected specimens also in N. W. N. G., meanwhile 

 Beccari and d'Albertis procured specimens at Sorong, and 

 Beccari at Doreh. 



106. Dendi'olagus dorianus Ramsay. 



From the Mount Astrolabe region, S. E. New-Guinea. 

 Thomas remarked (Catalogue, 1888, p. 98): " the rever- 

 sal of the whole of the fur of the back and the great 

 proportional size of the first incisors are both characters 

 of so much importance as to show that dorianus is a 

 species very distinct from any of the other members of 

 the genus; head and body 750 mm., tail 610 mm.; skull: 

 basal length (?) 132 mm., greatest breadth 69 mm." Mr. 

 Waite (Records Austr. Museum, Vol. II, 1892—96, p. 85) 

 exhibitet other specimens from the same locality, among which 

 only one with a skull and this has the occipital region 

 cut; he gave the following figures of the latter : basal length
