The animals of the class Polypiaria, differ from the Sea 
Anemones, and the Zoanthi, by the mouth being provided 
with only a single series of long tentacula, by the body 
being more slender, and by the cells which they form 
being quite simple, or without any radiating laminae. 
The genera belonging to the class Polypiaria are distri¬ 
buted as follows:—

The true Zoophytes, are so called from the general re¬ 
semblance which their corals bear to plants : some of them 
form a horny, and others a calcareous coral. They con-
