284 Description of two additional Crania of the 
brutes, the expanded portion of the nasals between the 
frontal,—or an additional osseous element, if this prove an 
independent bone,—the vertically broader and more arched 
zygomata, contrasting with the more slender and horizontal 
ones of the Chimpanzée, the more quadrate foramen lacerum 
of the orbit, the less perfect infra-orbitar canal, the orbits less 
distinctly defined, the larger and more tumid cheek-bones, 
the more quadrangular orifice with its depressed floor, the 
greater length of the ossa palati, the more widely-expanded 
tympanic cells, extending not only to the mastoid process, 
but to the squamous portion of the temporal bones,—these 
would of themselves be sufficient to counterbalance all the 
anatomical characters stated by Professor Owen, in support 
of the more anthropoid character of the Engé-ena. 
When, however, we add to them the more quadrate outline 
of the upper jaws, the existence of much larger and more 
deeply-grooved canines, molars with cusps on the outer side, 
longer and more sharply pointed, the dentes sapientiz of 
equal size with the other molars, the prominent ridge be- 
tween the outer posterior and the anterior inner cusps, the 
absence of a crista-galli, a cranial cavity almost wholly be- 
hind the orbits of the eyes, the less perfectly marked depres- 
sions for the cerebral convolutions, and above all, the small 
cranial capacity in proportion to the size of the body, no 
reasonable ground for doubt remains, that the Engé-ena oe- 
cupies a lower position, and consequently recedes farther 
from Man than the Chimpanzée. 
It does not appear that any other bones of the skeleton 
have as yet fallen into the hands of any European naturalist. 
A description of some of the more important of them will be 
found in the Memoir above referred to,* in which it will be 
seen that there are two anthropoid features of some import- 
ance, which go to support the view advanced by Professor 
Owen, and these are the comparative length of the humerus 
and ulna, the former being seventeen, and the latter only 
fourteen inches, and in the proportions of the pelvis. This last 
is of gigantic size, and is a little shorter in proportion to its 
breadth than in 7. niger. prime.
