Specimens will generally be found in the collection of the 
Common Boa .{Boa constrictor ) of South America, the Emperor 
Boa ( 3 . imp erat or), the Tree Boa {Epic rates angulifer ) of 
Cuba, the Coppery Boa (E . cupreus ) from Trinidad, and 
the Anaconda {Eunectes murinus'). The genus Epicraies 
belongs to a section of the family which are distinctively 
known as tree boas; they are rarely more than seven or eight 
feet long, are arboreal in habit, and are found in the West 
Indies and Guiana. Cor alius hortulanus and C. ruschenber- 
geri are also tree boas, the latter species being very rare. 
Certain small-sized boas have developed a habit of burrow¬ 
ing, and live under ground. The Indian Eryx ( Eryx johni ), 
Conical Eryx ( E . conicus ) of India, as well as Botta’s 
Snake ( Charina bottoe) of California, are examples of these. 
The pythons represent in the Old World the boas of 
America; among them are the Indian Python (. Python 
molurus ), the Two-lined Python (. P . bivitiatus ), the Royal 
Python {P. regius ), and the West-African Python { 3 . sebce ). 
In spite of the enormous size reached by these serpents, their 
destructive powers are largely exaggerated, and it may be 
considered doubtful if any of them are dangerous to human 
life. 
Comparatively small members of the Boidce are the Car¬ 
pet Snake {Python spilotes) of Australia and the Madagas¬ 
car Boa {Boa madagascariensis ). 
The lizards are distributed throughout the world, being 
most common in the tropics and the warmer parts of the tem¬ 
perate zone. There are some nineteen hundred known species 
belonging to the order Lacertilia. Among the most common 
North American forms are :— 
The Striped Lizard {Eumeces fasciatus), Middle Atlantic 
and Southern States. 
The Six-lined Lizard {Cnemidophorus sexlineatus ), South¬ 
ern States. 
The Brown Lizard {Sceloporus undulatus ), Southern States. 
The Horned Lizard {Phrynosoma cornuta ), South-western 
United States and Mexico. 
Douglass’ Horned Lizard {P. douglassi ), Western States. 
Crowned Horned Lizard {P. coronata ), Western States. 
Short-nosed Horned Lizard {P. platyrhina ), Western 
States. 
The Green Lizard {Anolis principalis ), Southern States.
