4 CATALOGUE OF MAMMALS FROM NEW GUINEA. 
Reinhardt from the northern part of Celebes, the natives of which 
have not observed any varieties in colouring. 
2. P. chrysorrhos is described from two specimens brought home 
by the same Professor, from some of the Moluccas, which have a short 
cottony fur, of an ash-grey more or less black, and the rump and 
upper part of the base of the tail golden-yellow. 
3. Of P. maculata Herr Temminck particularly observes, that the 
fur in all ages and in both sexes is covered with irregular white or 
brown spots, which are paler and less marked in the young. The 
very young are sometimes entirely ashy. They come from Banda 
and Amboyna. 
The yellow colour of the rump and the base of the tail, as far as 
the specimens in the British Museum show, is common to the ashy 
specimens, which might be called P. chrysorrhos, and the variegated 
specimens, which might be named P. maculata: it is very diffi- 
cult to distinguish the pale-rumped ashy ones from those without 
that mark; but it is easy to connect the grey or ashy-spotted ones 
with either the one or the other; and it is impossible to-separate 
the ashy-grey spotted ones from the brown or orange spotted speci- 
mens. In one specimen the animal is nearly white, “With some small 
dark spots about an inch over; and-in another the animal is white, 
with red feet, and one large red spot on the middle of the back. 
From the examination BE the specimens in the British Museum, 
and of their skulls, I ‘am inclined to believe that the P. ursina is 
distinct, and that P. chrysorrhos and P. maculata are varieties of the 
same species. 
Mr. Wallace having sent two specimens of this genus to the British 
Museum, to determine them I went over the previous observ ations on 
the genus, and examined the numerous specimens which are in the 
Museum collection, received from the French voyages of discovery, 
Mr. J. Macgillivray, the Naturalist of H.M. Ship ‘ Rattlesnake,’ 
aud those now sent from the Island of Ula; and I have come to the 
belief that they are all to be referred to four species, which are very 
variable in the colour of the fur ; one being variable in both the sexes, 
and the other, in which the sexes differ greatly from each other, 
but appear to be permanent in their colour ; one species in which 
the furs of the two sexes are alike and uniform in colour; and one, 
of which the female sex only is known, which is uniform iron-grey. 
The two have the ears small, hairy on both sides, and hidden in 
the fur; the other two have larger ears, exposed beyond the fur and 
bald within.
