is short, stout, round, and frequently distorted into rounded 
protuberances. The branches are compressed, especially to- 
wards their terminations. Except the terminations of tl> e 
branches, the whole of the surface is roughly granular, fron 1 
the irregular growth of the cells. The cells are urceolat®> 
partially imbedded, and distributed over all parts of tlC 
polvpidom. The apertures are round, with a notch on th® 
inferior margin anil an obscure wave on the superior on 0 ' 
At the termination of the branches the surface is smooth, 
the apertures of the cells only appearing. The granm?f 
surface is produced by the super-position of cells on the pl al j 
first layer. When living, the polypidom is of a delicate 
colour, which afterwards changes to a dusky brown; and 1 
frequently has a varnished appearance. Borlase, in hi 
Natural History of Cornwall has a characteristic figure 0 
this species but the figure given by Dr. Johnston is s 
entirely unlike any specimen of the great number I 
procured, that it seems to be a distinct species approacbiwj 
to Eschara. In this opinion I am supported by seve> a 
friends to whom I have submitted specimens for comparis 0 
with the Doctor’s figure.

This calcareous coral attains occasionally the height of 
inches, but it is more commonly met with about one. 1° ^ 
living stale it is of a reddish flesh colour, or pink, wb' 0 
always fades in death, and sometimes becomes of a p 0ar f 
white tint. It is stout, slightly compressed, rough and 
chotomously branched. The roughness, which is confined.^ 
the branches, is produced by the lormation of new cells.
