MUS BARTELSII. 69 
NOTE IL. 
ON A NEW MOUSE FROM JAVA 
BY 
Dr. F. A. JENTINK. 
May 1910. 
A mouse, collected by Mr. Bartels, April 1903, at an 
altitude of 6000 feet on the Pangerango-mountain, Java, 
was presented by that gentleman to our Museum. 
In comparing it with our Javan Mice I see that the 
animal differs enough to bestow it with a new specific title. 
Superficially it reminds my Mus lepturus, also from Java, 
however without more exact locality on that island ; especially 
striking is the very elongated fur of the upperparts, indi- 
cating their origin of elevated localities. 1 propose the name 
Mus Bartelsii, n. sp. 
The extremely soft hairs of the back of a dark mouse- 
color; each hair tipped with sooty black, towards the neck 
and head and the sides the hairs are tipped with maho- 
gany; posterior extremities and base of tail colored like 
back, anterior extremities like sides of body; underparts 
have the hairs of a mouse-color, tipped with pure white; 
hands and feet with short straw-colored hairs, on their 
basal parts a dark patch; tail basally blackish, passing 
gradually towards its (incomplete) end into a yellow tinge; 
hairs of tail extremely short, scales very small, smaller 
than in lepturus. Kars much shorter than in the latter 
species, rounded at the tip, about as broad as long. As 
with trapped small animals generally, the skull has poste- 
riorly been smashed, so that its length cannot be given.
