Hab. In deeper water than the last, but sometimes mixed 

 with it in deep pools. 



This coralline very much resembles the last, of which it 

 appears to he only a variety. It grows to a greater length, 

 is more slender, and more branched and the branches more 

 filiform than the C. officinalis, and is prostrate instead of 

 being semi-erect. 



C. SQUAMATA. Calcareous, jointed, trichotomously 

 branched, joints compressed, two edged.

This delicate species is most commonly of a delicate pea- 

 green colour. It resembles the C. officinalis in general 

 appearance, but is undoubtedly distinct from it. The inter- 

 nodes are wider in proportion to their length and more 

 compressed than in that species. The branches are erecto- 

 patent, joints linear, pointed and compressed at the edges. 

 The compression of the edges is a character which is always 

 present.

lhib. On the common coralline, in pools; very common. 



When recent it is of a reddish brown colour, paler 

 towards the edges. It enerusts the stems of the common 

 coralline, of which it is thought to be a variety, and sends 

 off horizontal semi-circular plates, which are turned op at 

 their edges. When recent, it will be found marked by
