Enge-ena, from Gaboon, Africa. 281 
maxillary bones form a projecting ridge on the median line, 
both in and below the nasal orifice, and at the middle of the 
border of this opening form the projecting “ nasal spine,” 
which is not met with in any of the lower animals, and is, 
therefore, an anatomical character peculiar to man. With re- 
gard to this conformation of the intermaxillary bones, the 
Engé-ena recedes farther from man than the Chimpanzee. 
Two infra-orbitar foramina exist on each side. The crests 
are not so well developed as in the cranium just described. 
The occiput having been in part destroyed, the cavity of the 
cranium is completely exposed. A groove for the lodgement 
of the longitudinal sinus is well defined; “ digital impres- 
sions,’ formed by the cerebral convolutions, exist, but not 
well marked, the crista-galli is merely rudimentary, and is 
represented by a very slight median ridge, the olfactory fossa 
is quite deep, the cribriform plate being on a level with the 
middle of the orbit; about five parallel grooves for the 
lodgement of the branches of the dura matral artery exist on 
each side. 
Zoological position of the Engé-ena. 
With the knowledge of the anthropoid animals of Asia and 
Africa which now exist, derived from the critical examina- 
tions of their osteology, their dentition, and the comparative 
size of their brains, by various observers, especially Geoffroy, 
Tiedemann, Vrolik, Cuvier, and Owen, it becomes quite easy 
to measure, with an approximation to accuracy, the hiatus 
which separates them from the lowest of the human race. 
The existence of four hands instead of two, the inability to 
stand erect, consequent on the structure of askeleton adapted 
almost exclusively to an arboreal life, the excessive length of 
the arms, the comparatively short and permanently flexed 
legs, the protruding face, the position of the occipital con- 
dyles in the posterior third of the base of the skull, and the 
consequent preponderance of the head forwards, the small 
comparative size of the brain, the largely-developed canines, 
the interval between these last and the incisors, the three 
_ roots to the bicusped teeth, the laryngeal pouches, the elon- 
gated pelvis, and its larger antero-posterior diameter, the
