Mias pappan is the _Simia Wurmbii_ of Mr. Owen, having callosities
on the sides of the face: the natives treat with derision the idea
of the Mias kassar, or _Simia morio_, being the female of the Mias
pappan or Simia Wurmbii; and I consider the fact can be established
so clearly that I will not trouble you with their statements: both
Malays and Dyaks are positive that the female of the Mias pappan has
cheek-callosities the same as the male; and if on inquiry it prove
to be so, the existence of three distinct species in Borneo will
be established. The existence of the Mias rombi is vouched by a few
natives only, but they were men of intelligence, and well acquainted
with the animals in the wild state. They represent the Mias rombi to
be as tall as the pappan, or even taller, but not so stout, with longer
hair, a smaller face, and no callosities either on the male or female;
and they always insisted that it was not the female of the pappan.

The Mias kassar or Simia morio is of the same color as the Mias pappan,
but altogether smaller, and devoid of callosities either on the male
or female adults.

By the native statements, therefore, we find three distinct species,
viz. the Mias pappan or Simia Wurmbii, the Mias kassar or Simia morio,
and the Mias rombi, which is either the _Simia Abelii_, or a fourth
species. The existence of the Sumatran ourang in Borneo is by no
means impossible; and I have already compared so many of the native
statements, that I place more confidence in them than I did formerly,
more especially as their account is in a great measure borne out by
the skulls in my possession. I had an opportunity of seeing the Mias
pappan and the Mias kassar in their native woods, and killing one of
the former and several of the latter species. The distribution of these
animals is worthy of notice, as they are found both at Pontiana and
Sambas in considerable numbers, and at Sadung on the northwest coast,
but are unknown in the intermediate country which includes the rivers
of Sarawak and Samarahan. I confess myself at a loss to account for
their absence on the Sarawak and Samarahan rivers, which abound with
fruit, and have forests similar and contiguous to the Sadung, Linga,
and other rivers. The distance from Samarahan to Sadung does not
exceed twenty-five miles; and though pretty abundant on the latter,
they are unknown on the former river. From Sadung, proceeding to the
northward and eastward, they are fou
