madeari than appears at first sight , for withhi the group of 

 large species with white tipped tails, of which a short synopsis 

 was given in tlie original description of that animal, it differs 

 by most of the ciiaracters which separate the species from one 

 another, notably by its black head and rump, its non-possession 

 of elongated dorsal bristles, and its siiort palatal foramina. The 

 otiier species there mentioned are all more or less greyish 

 instead of rufous, while the additional one since described by 

 Dr. Jentink from Flores, Mus armandvillei {^), is readily distin- 

 guished from the present and evei-y otiier species by its enor- 

 mous size. 



It is unfortunate that all tlic specimens of Mus siporanm are 

 males, so that I am unable to record the very important cha- 

 racter of the mammary formula.

In the possession of a bright rufous collar this specimen 

 agrees with tlie Kina Balu skins mentioned in my recently 

 published description of the species (-), rather than with the 

 typical lowland ones. It shows therefore that I should have been 

 wrong to describe tlie collared variety as a species or subspecies 

 peculiar to that mountain, as I had at first believed to be 

 necessary.

One of the ordinary dark coloured forms belonging to the 

 Mus rattus ^Yo\\\), with 2-3=10mamma\ Exact determination 

 within this group is for the present entirely out of the ques- 

 tion, owing to the large number of described species and the 

 paucity of proper material.
