232 On Two new North- Born eaJi Mammals. 



Besides the type, a second specimen, in most respects 

 precisely similar and also a male, was obtained by Mr. Everett 

 at tlie same time and place. 



This handsome monkey seems only to be nearly allied to the 

 species above referred to. Of these it differs from S. Hosei 

 and S, Everetti by its vertical frontal cre«t, its greyish crown 

 surrounded by black instead of black surrounded by white, 

 and its greyish nape and sides of neck, where there is none of 

 the sharp contrast between black and white characteristic of 

 those species ; the legs also above the ankles are grey instead 

 of black. 



From S. Tkomasi, which Jilso has a crest, it is distinguished 

 by its backwardly directed occipital hairs, its perfectly unicolor 

 tail, its paler back, and by the lesser extension and purity of 

 the white of the belly and inner surface of the limbs. 



In addition, as already noted, S. sahanus is distinguished 

 from all its allies by the whitish or flesh-coloured tint of the 

 upper half of its face. 



Mus Margarettce pusilluSj subsp. n. 



Apparently similar in every way to the typical form, but 

 very markedly smaller in all dimensions, as is shown by the 

 following measurements of the type (an adult female in 

 alcohol) : — 



Head and body 67 millim., tail 123; hind foot without 

 claws 1G"8 ; ear from notch 13'8. 



Skull: basal length 19*1, upper length 22*6 ,• zygomatic 

 breadth 12-2, breadth of brain-case 11 ; nasals, length 7'3 ; 

 interorbital breadth 39 ; interparietal, length 3*2, breadth %'6 ; 

 anterior zygoma-root 2'0; palate, length ll'o; diastema G'l ; 

 anterior palatine foramina o'O ; length of upper molar 

 series 3"0. 



Eah. Mount Kina Balu, N. Borneo. Coll. A. Everett. 



This beautiful little mouse is evidently a local represen- 

 tative of the very remarkable species 1 described as Mus 

 Margaretice, i'rom the Penrisen Hills, Western Sarawak*, and 

 as such deserves a subspecific name. The specimen is 

 distinctly older than the original type of the species, and is of 

 the same sex, so that the difference in size is clearly due 

 neither to age nor sex. 



A second specimen, identical in all respects with that now 

 described, was sent home by Mr. Everett, but was not acquired 

 for the Museum collection.
