having a single series of separate well-developed polype-cells 
on each of the two edges of the branches and branchlets.

ANICELLA. 
Coral fan-like, dichotomously branched ; branches separate, 
divaricating, in the same plane, arising from the short, rather 
sunken joimts. Bark thin, hard, smooth, longitudinally 
grooved. Cells minute, subcylindrical, short, produced in a 
narrow alternating series on each edge of the branches and 
branchlets. Axis calcareous, solid, with longitudinal grooves ; 
internodes very short, contracted, bark-like. 
This genus differs from Melithea in the bark being smooth, 
and the internodes not swollen, and from Js7s in the internodes 
being bark-like and not cartilaginous. 
Anicella australis. Fig. 4. 
Coral red, growing in one plane; the stem distinctly jointed ; 
the branchlets slender, with the joints very inconspicuous.
