CINCINNATI ZOO GUIDE 
The Green Snake ( Cyclopis vernalis). This is closely allied to 
the preceding species. It is also a native of America. Its color is 
grass green and it is singularly active. 
Boas and Pythons. As stated elsewhere, they have no poison¬ 
ous fangs, but are regarded as dangerous snakes because they 
have a characteristic constricting organization. The name of 
boa constrictor is popularly applied to all of them, but true 
boas are found in the tropics of the New World. The most 
prominent members of the constricting reptiles are the Ana¬ 
conda and the Boa of South America and the Python ( Python 
sabae) of Africa. They kill their prey by compression, and the 
articulation of their jaws and lips admit of great distension, so 
that they can, without difficulty, swallow animals much larger 
than themselves. Many strange stories are told of the sizes to 
which they attain, but it is not probable that they are more than 
thirty feet in length. 
THE SQUIRREL CAGE 
South of the Reptile Cage will be found the Squirrel Cage. 
In the collection are generally to be found the Common Fox 
Squirrel ( Sciurus vulpinus ), United States, the Gray Squirrel 
(S. carolinensis ), United States, the Black Squirrel ( S . niger ), 
Canada, and the Southern Fox Squirrel ( Sciurus var ciner- 
cus ), Southern States. 
The gray squirrel is subject to color variation. The black and 
the white squirrel belong to the gray species. Opposite the 
Squirrel Cage is the Summer Garden and Pergola. 
WINTER QUARTERS 
From the Pergola take the main walk leading to the Club 
House. On the east end of the Club House take the walk leading 
to the bridge. Before crossing the bridge, take walk to the left 
leading to the Winter Quarters. This building is occupied in the 
summer time by a miscellaneous collection of fancy chickens, 
pigeons, rabbits and large snakes. 
In the winter the rabbits, pigeons and chickens are removed
