Habits and Osteology of a New Orang. 421 
examination, and I now proceed to give the results of my 
investigations on its External Characters and Habits. 
It should be borne in mind that my account is based upon 
the statements of the aborigines of that region. In this con- 
nection it may be proper for me also to remark, that having 
been a missionary, resident for several years, studying from 
habitual intercourse, the African mind and character, I felt 
myself prepared to discriminate and decide upon the proba- 
bility-of their statements. Besides, being familiar with the 
history and habits of its interesting congener, (Troglodytes 
niger, Geoff.) 1 was able to separate their accounts of the two 
animals, which, having the same locality and a similarity of 
habit are confounded in the minds of the mass, especially as 
but few, such as traders to the interior and huntsmen, have 
ever seen the animal in question. In this last fact stated we 
find an explanation of the confusion, inaccuracy and exagger- 
ation which characterize the occasional references that have 
been made in books to both animals, the sources of such in- 
formation being transient visitors and voyagers. If it be ad- 
missible to base and sustain a proposition on human testimony, 
then to my mind the existence of this new species of orang, 
aside from the evidence of its skeleton, is established, and the 
account that I now submit of its habits, authentic. It is on 
Such grounds, and with such convictions I venture to place my 
. Sütements on record, leaving them to the future for confirma- 
tion or correction. 
_ The tribe from which our knowledge of the animal is de-

The river is visited for purposes of trade in ivory, ebony and
