that the living of this species both in New-Guinea and on 
the Arou-islands, is another proof for their land-connection 
in times past. However, notwithstanding there seems to be 
no doubt about the original locality — the Arou-islands — 
it is a very remarkable fact, that nobody since 1875 saw 
another specimen from the named islands, the more strange 
as before Beccari our traveller Baron von Rosenberg col- 
lected specimens, now in the Leyden Museum, of Pha- 
langer maculatus as well as of Phalanger orientalis on these 
islands, and Wallace too procured from there specimens, 
now in the British Museum, belonging to these two species. 
This may be as it is, it remains however a fact that 
Peters described the species in such clear terms, that 
merely lack of material may be an excuse why later authors 
failed to accept it as a species distinct from Phalanger 
orientalis. Indeed, extremely striking is the kind of fur and 
its colour as well as the naked tail, only adorned with a 
rather small ring of fur round its base; moreover the 
skull, concave like in orientalis, presents a dentition quite 
distinct from that of the latter species, especially by the 
very stout posterior premolar (p*) in the upper- as well 
as in the lower jaw, placed by far not so correctly 
in the molar-row as is the case in all other Phalanger- 
species. 
Phascogale Lorentzti, n. sp. 
N° 329. Young adult 9. Hellwig Mts. (2600 M.), October 24, 1909 
(skin and skeleton). With four youngs in pouch. - 
This animal is characterized by its large size, long fur, 
shining black colour, white ears, white extremity of tail 
and very elongated claws. 
The fur is very long, longer than in any other Phasco- 
gale known to me, very dense — not adpressed like in 
other Phascogale-species — and very soft to the touch. Head 
with thickly set black hairs, like the anterior part of the 
back, broadly between the shoulders, and like the posterior
