I add a few notes upon some of the rarer species of the col- 
lection :— 
1. MACACUS SPECIOSUS. 
Inuus (Macacus) speciosus, Temm. F. J. Mamm. pls. 1, 2, p. 9. 
Of this rare Monkey we have a fine young male specimen, pur- 
chased from a dealer in Liverpool in June last, said to have come 
from “ Brazil’?! Iam not aware that it has been previously brought 
to England alive, although there was a specimen in the Gardens at 
Rotterdam some time since. 
2. Macacus cyctopis, Swinhoe, P. Z.S. 1862, p. 350, pl. xxi. 
The pair of this species presented by Mr. Swinhoe in 1862 are 
still in good health in the Society’s Menagerie. Since they have 
attained maturity, the female has acquired a most extraordinary de- 
velopment of the parts surrounding the organs of generation—far 
exceeding anything I have ever noticed in the Rhesus Monkey—of 
which the accompanying sketch (see p. 711) will give some idea. 
An accurate examination of this species has still to be made, Mr. 
Swinhoe’s notes having being taken from the living animal ; but I 
have little doubt that when narrowly compared with M. rhesus good 
points of distinction will present themselves.
