No. 1626. MAMMALS FROM HASTHERN SUMATRA—LYON. 677 
The Orang-utan do not occur so far south as the Siak River, at least near 
the coast. No one seems to know the southern limit of its range. 
The natives mentioned a third sort of Mawas [that is in addition to the 
“large” and the “small” species] which I did not meet with. They called it 
Mawas orang (literally man orang) and said it was nearly naked. It was said 
to occur back in the mountainous districts and also up the Besitan, where I spent 
eight days without seeing anything but the two ordinary species.—W. L. Abbott.
