Adeona (Lamx.). Leaf-like expansion of the polyzoarium composed of 
two laminae, in which the zooecia are placed in an oblique direction; 
zooecia similar to those of Eschara, their mouth rounded or lunate, some- 
times a small accessory pore beneath it ; near the mouth an avicularium, 
the lower claw of which is immersed in the wall of the zooecium ; the 
external calcareous stratum of the zooecium perforated by numerous 
pores, which, however, do not penetrate through the whole thickness of 
its wall. Stem and branches without zooecia or crust ; they contain in 
their interior the same two rows of zooecia as the blades, but these are 
covered by the calcareous deposit which forms the branch, and their 
mouths are obsolete ; the formation of the branches is therefore posterior 
to that of the zooecia, and the branches are wanting in A. cellulosa. Basal 
stalk and root-liko prolongations fiexible, composed of alternating calca- 
reous swollen rings and a tubular chitinous substance. A. foliacca
