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 of 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 observations 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,' 

 and 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.
