CORAL-MAKING POLYPS. 47 
the polyp; and this is true of all the living Fungie studied 
by the author. It is plain that the power of such tentacles 
must reside wholly in their lasso-cells.

TENTACLE OF FUNGIA LACERA, ENLARGED. 
The tentacles are scattered over the disk. instead of being 
in regular circles. Nevertheless, there is a regular order of 
development, as stated on page 27; a fact which shows that 
the apparent irregularity is a consequence of the unusual 
size of the polyp and the consequent larger number of the 
radiating lamellae and polyps. 
The Fungie, unlike most corals, are not fixed animals 
except in the young state. They are common in coral-reef 
seas, lying over the sandy or rocky bottom between the other 
corals. 
Other varieties of corals and coral animals are illustrated 
in the figures on the following pages. They represent com- 
pound groups, in which great numbers of polyps are con- 

nected in a single zobphyte—a result, in part, of the process 
of budding already alluded to, and partly of different modes 
of growth connected therewith. 
This budding is very similar to the budding process in 
vegetation. One common method is the same that is occa- 
sionally met with in Actinixw, the description of which is 
briefly given on page 40. The bud commences as a slight
