ZOOLOGICAL GARDENS.

Anthropoids are kept in another part of the Gardens 
and will be described afterwards, while the second group 
is represented in this and also in the Jheend House 
and in some small cages distributed throughout the Gardens. 
Of this latter group there are two well-marked genera 
exhibited in this house, the genus Semnopithecus without 
cheek-pouches, and the genus Macacus which has these 
sacs, all having tails generally well developed, but 
differing from each other in dentition, the form of 
the skull, and the structure of the stomach,—this last 
anatomical feature being one of considerable im¬ 
portance. In the genus Macacus the stomach is a simple 
sac as in man ; whereas in Semnopithecus it is, as far as we 
know, throughout the genus, a much sacculated organ. 
These last monkeys feed largely upon the leaves of trees, 
and it is interesting to observe the manner in which, by 
one sweep of their hand, they strip the leaflets from off a 
pinnate leaf; whereas the food of the Macaques is much 
more varied. 
The Langur or Hunaman monkey, S. entellus , is a large 
powerful animal, generally distributed over the greater 
part of India, and is represented in the Himalaya by even 
a more powerful monkey, viz., the Hill-Langur which some 
have supposed to be a distinct species, although perhaps 
it would be more accurate to regard it as only a mountain 
race which ascends to considerable altitudes. The Langur 
and the other Semnopitheci, are essentially gregarious, and 
the experience gained in these Gardens has been, that the 
only way to keep any alive is to have a considerable number 
of one species together, otherwise they pine and die. 
It is well known to sportsmen that the Langurs 
from their heights among the trees, are very observant of
