SEVENTEENTH GENUS—ACROCHORDIDA. 
Wart Snakes. Some species are not venomous, and others 
are known to be exceedingly so. Hast India species are, viz.: 
No. 1. Acrochordon xenodermis. 1 variety. 
2. Acro. javanicus, 8 ft. long. 1 “ (Java). 
3. Acro. chersydrus. Jo 38 
One of the preceding varieties, called Oular carron, is 
often eaten by the natives in India, and its. flesh esteemed 
very delicious.

brown, dark-colored, and cream-colored spots, some of the 
dark ones approaching to a greenish hue. Immediately after 
the death of the snake, a thick, milk-like liquid exudes from
