trees. If there is a young one, it goes with the mother. These 
retreats are only built for a very temporary residence, and are not 
used for more than eight or ten days, and for the following reason. 
When the Nshiego has ravaged a certain extent of country 
around its habitation, it betakes itself to another quarter, where it 
prepares a new residence. 
This species is distinguished from the ordinary Chimpanzee 
( Troglodytes niger ) by the absence of hair on the head ; this is 
why M. du Chaillu has proposed to name it the Bald Chimpanzee 
(Troglodytes calvus ) . 
In one of his excursions, M. du Chaillu killed a female Hshiego 
carrying her young one in her arms, which he took to his resi- 
dence. In a few days it was so completely tamed that he could 
allow it to wander at liberty without fear of it running away. He 
could not move a step without being followed by the youngster ;

had satisfied itself with this examination, hastened to carry off 
some bananas. If, on the contrary, the sleeper moved in his bed, 
the Monkey disappeared like a flash of lightning, and came in 
again a few minutes afterwards to go through the same 
manoeuvres. 
“ If I opened my eyes,” adds M. du Chaillu, “ while it was in 
the act of committing theft, it all at once assumed an honest 
air and came to caress me ; but I could readily detect it darting 
furtive glances towards the bananas. 
“ My cabin had no door, but was closed by a mat. Nothing 
could be more comical than to see Tommy quietly raising a corner 
of this mat to see if I was asleep. Sometimes I feigned to be
