ZOOPHYTA. ESCHARADiE. Cellefora. 
Gen. LII. CELLEPORA. — Cells agglomerated, presenting 
various forms. 
157. C. Substance loosely cellular, the cells or- 
bicular, the mouth round, with a produced marginal process. 
Eschara millepora lapidea, instar pumicis porosa, Ellis^ Coral. 75, t. xxx. 
f. D. — Millepora pumicosa, Pallas, El. 254 — Eliistra bullota, Sol. Ellis 
Zooph. 16. — Investing the stems of fuci. 
When young the cells are remarkable for their rounded form, but they be- 
come less regular as they multiply gemmiparously, and are piled upon one 
another without order, when the mass bears a very close resemblance to pu- 
mice-stone. 
158. C. cervicornis. — Branched, compressed, rough, mouths 
of the cells slightly marginated, with a blunt process on the 
upper side. 
Porus cervinus Imperati, Borl. Com. 240, t. xxiv. f. 7- — Millepora cerv. 
Pall. 252 — M. compressa, Soiver. Brit. Misc. t. Ixi — In deep water, 
not rare. 
Stem rising to the height of several inches, dichotomously divided, the 
branches spreading; rough, with the half formed cells; the extremities of 
the branches are compressed, even, and thin, consisting of a single layer of 
cells on each side regularly placed. In this state it accords with the Mille- 
pora Skenii of Sol. Ellis, Zooph. 135. It afterwards increases irregularly in 
thickness, becoming rounder. It is of a pale brownish colour, and looks 
sometimes as if varnished. 
129. C. palmata . — Base round, suddenly expanding on each 
side into a compressed, slightly divided head, the cells with a 
tooth on the proximal margin. 
A single specimen from deep water, Zetland. 
Height about half an inch, breadth an inch, stem about two-tenths ; rough, 
the little branches are short and truncated ; the orifices of the cells are de- 
clining, and nearly concealed by the spinous processes, which are rather long, 
and give the surface a muricated aspect ; the substance is somewhat compact. 
ISO. C. Dichotomously branched, cylindrical, the 
pores wide, with simple mouths. 
A single specimen from deep water, Zetland. 
Height an inch and a quarter, diameter one-tenth ; the branches are 
smooth, with the orifices of the cells smooth and concave ; towards the ex- 
tremities the branches are rough with the forming cells, and the orifices are 
more declining, circumscribed, a little prominent, with a blunt process at the 
proximal margin. 
131. C. —Dichotomously branched, the branches 
round and confluent ; cells prominent, with a produced spinous 
process on the proximal mai’gin. 
Linn. Syst. i. 1285. — Millepora pumicosa var. Sol. Ellis, Zooph. 136. 
Cordiner's Iluins, No. xiv. — In deep water, not rare. 
Height of the largest specimen in my possession about an inch and a half, 
the thickness of the branches scarcely a line, and their length less than half
