Habits and Osteology of a New Orang. 493 
The animal has the power of moving the scalp freely forward 
and back, and when enraged, is said to contract it strongly 
over the brow, thus bringing down the hairy ridge, and point- 
ingthe hair forward so as to present an indescribably ferocious 
aspect. 
Neck short, thick and hairy; chest and shoulders very 
broad, said to be fully double the size of the Enché-eko's; arms 
very long, reaching some way below the knee, the forearm 
much the shortest; hands very large, the thumbs much larger 
than the fingers. 
Abdomen very broad and prominent, the hair thinner than 
on the back, legs bowed like the Chimpanzée’s, but the muscles

No tail nor callosities ; a small tuft of hair at the extremity

the Chimpanzée it does not stoop as much in walking; like 
that animal it makes progression by thrusting its arms forward,

‘esting on the knuckles, but to extend them, thus making a 
fulerum of the hand. When it assumes the walking posture 
to Which itis said to be much inclined, it balances its huge 
Xy by flexing the arms upward. They live in bands, but 
are not so numerous as the Chimpanzée’s ; the females generally 
exceed the other sex in number. My informants all agree in 
assertion that but one adult male is seen in a band ; that 
the young males grow up, a contest takes place for mas-
