4. Nores on a Sprper Monkey (ATEtEs cucu.tatus, Gray) 
LATELY LIVING IN THE Socrety’s MenaGerisz. By Dr. J. 
Mouriz, Prosecror To THE Society. 
An adult male specimen of this Spider Monkey was purchased by 
the Superintendent of the Society’s Gardens from a dealer in Liver- 
pool in May 1865. It was said to have come from South America. 
The animal seemed in a fair state of health until shortly before 
its death, which took place on the 23rd of August, 1865. 
Immediately on receipt of the body, notes were taken of the co- 
lour and general appearance, wherein it differed somewhat from the 
known species of the genus; and Dr. Gray has thought these suffi- 
ciently characteristic to entitle the animal to a separate specific 
name. His description of the same from the skin* embodies the 
distinctive differences. It, however, may be worth while remarking 
that while alive the skin around the orbits and upon the nose was 
bare, and of a brownish flesh-colour with darker freckles intermixed 
(somewhat sunburnt-like). The cheeks and lower jaw were also 
nearly bare of hair, but the skin more decidedly of a black shade. 
The following measurements were taken shortly after the animal 
had died :—
