tual intercourse, the
African mind and character, I felt myself prepared to discriminate and
decide upon the probability of their statements. Besides, being familiar
with the history and habits of its interesting congener ('Trog. niger',
Geoff.), I 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.

(FIGURE 10.--The Gorilla (after Wolff).)

"The tribe from which our knowledge of the animal is derived, and whose
territory forms its habitat, is the 'Mpongwe', occupying both banks of
the River Gaboon, from its mouth to some fifty or sixty miles upward....

"If the word 'Pongo' be of African origin, it is probably a corruption
of the word 'Mpongwe', the name of the tribe on the banks of the Gaboon,
and hence applied to the region they inhabit. Their local name for the
Chimpanzee is 'Enche-eko', as near as it can be Anglicized, from which
the common term 'Jocko' probably comes. The Mpongwe appellation for its
new congener is 'Enge-ena', prolonging the sound of the first vowel, and
slightly sounding the second.

"The habitat of the 'Enge-ena' is the interior of lower Guinea, whilst
that of the 'Enche-eko' is nearer the sea-board.

"Its height is about five feet; it is disproportionately broad across
the shoulders, thickly covered with coarse black hair, which is said to
be similar in its arrangement to that of the 'Enche-eko'; with age it
becomes grey, which fact has given rise to the report that both animals
are seen of different colours.

"HEAD.--The prominent features of the head are, the great width and
elongation of the face, the depth of the molar region, the branches
of the lower jaw being very deep and extending far backward, and the
comparative smallness of the cranial portion; the eyes are very large,
and said to be like those of the Enche-eko, a bright hazel; nose broad
and flat, slightly elevated towards the root; the muzzle broad, and
prominent lips and chin, with scattered gray hairs; the under lip highly
mobile, and capable of great elongation when the animal is enraged, then
hanging over the chin; skin of the face and ears naked, and of a dark
brown, approaching to black.

"The most remarkable feature of the head is a high ridge, or crest of
hair, in the course of the sagittal suture, which me
