I THE GORILLA. 65 



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. 



" 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 proba- 

 bly 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 Chim- 

 panzee is Enche-eko, as near as it can be Anglicised, 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 sound- 

 ing 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 gray, which 

 fact has given rise to the report that both animals are 

 seen of different colours. 



" Bead. — 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 scat- 

 tered gray hairs ; the under lip highly mobile, and capable
