MAMMALS FROM NEW GUINEA 613 



mammae, and are all undoubtedly very closely allied to. each 

 other. Much larger series of specimens from the different islands 

 of the archipelago are needed before their relations to each other 

 can be properly determined.

?. Moroka, 13U0 m. July 1893. 



The type of " Mus mollipilosus ", from Katau, has been kindly 

 sent over to me by Dr. Gestro for comparison. The present 

 specimen, though rather larger, seems to accord very closely 

 with it, and should evidently be referred to the same species. 



This rat, and the two following, seem to be certainly members 

 of Milne-Edwards's genus Pogonomys (^) , in whose description , 

 however, no mention is made of the prehensile nature of the 

 tail, nor of the peculiarities of the dentition. 



This being the case, the question has arisen whether the still 

 more specialized species forbesi, made by me the type of a new 

 genus Chiruromys (^) , together with the allied forms pulcher 

 and lamia, should not also be placed in Pogonomys , of which 

 Chiruromys would then be a synonym. 



On the whole it seems best for the present to combine the 

 two groups in one genus, and I have therefore here placed all 

 the species under the name Pogonomys.
