FASCICULI MALATENSES 
"Type, Adult male, collected on the 9th May, 1901, Original number, 9. 
The grey colour forms a very conspicuous difference by which this race 
may be readily recognized. Specimens from the West Coast do not appear to 
differ from those found in Sumatra. A second specimen was procured from 
the same locality in August.

I have compared these specimens with some paratypes kindly lent me by 
Mr. Miller, and with which they perfectly agree. 
* These two specimens were trapped in the jungle with traps baited with 
melon rind, whereas Mus bukit came into our hut and were caught by the cook 
in the rice-bags.’

This series, which is slightly duller in colour, shows less black on the back 
than a series of paratypes forwarded to me for comparison by Mr. Miller. 
The species seems to be very largely an inhabitant of caves. The specimen 
brought home by the ‘ Skeat ’ expedition, and referred by me to Mus cremori¬ 
venter , belongs to the present species. Apart from other differences, Mus 
cremoriventer is much smaller and has a uniformly brown tail.
