Gen. LII. CELLEPORA. — Cells agglomerated, presenting 

 various forms. 



127. C. pumicosa. — Substance loosely cellular, the cells or- 

 bicular, the mouth round, with a produced marginal process.

 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. 



128. 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, Sower. 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. 



130. C. l(evis. — Dichotomously branched, cylindrical, the 

 pores wide, with simple mouths. 



A single specimen from dee}) 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 \\'ith the forming cells, and the orifices are 

 more declining, circumscribed, a little prominent, with a blunt process at the 

 proximal margin. 



131. C. ramulosa. — Dichotomously branched, the branches 

 round and confluent ; cells prominent, with a produced spinous 

 }>rocess on the proximal margin,

Cordiner's Ruins, 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 scarcelv a fine, and their length less than half
