PROLIFEROUS. 
19. Corallina prolifera . Small ramifications im-

pressed, and near two millemetres in breadth ; colour 
very white by desiccation ; height one decimetre.—

Coasts of the Bahamas. 
CYMOPOLIAo 
Polypi doms plant-like, necklace-formed, and di- 
chotomous ; articulations cylindrical and separated 
from each other ; polypean pores almost visible to 
the naked eye. 
Two species alone have served me to establish this 
genus, which differs from that of the Corallinas by the 
dichotomous ramifications, from that of the Galax- 
aura by the thickness of the cretaceous rind, and the 
smallness of the interior tubular axe ; it also differs 
from the Amphiroas by the regularity of its divisions 
which peculiarities distinctly separate them from any 
of these genera. They are easily recognized by the
