Hub. On fuci- Lantivet, Tallandsand, and Mevagissey 

 bays; common. 



Of a delicate pea green colour, which soon bleaches to 

 white, from exposure on the beach. This is the stoutest of 

 all the dichotoinously branching corallines found on our 

 coast. It is readily recognized, by the joints being some- 

 what compressed, and above being prolonged ou each side 

 into a horn. 



CORALLINA. 



Generic Character ; Arborescent, jointed ; the joints slightly 

 compressed, trichotomously branched. 



From this Genus being trichotomously branched, the 

 appearance of a primary stem is preserved, and the two 

 other branches, appear to rise from the sides. 



COMMON CORALLINE. C. Ojfldiialis. Arborescent, 

 jointed ; joints somewhat wedge-shaped with truncated 

 angles ; lateral offshoots short, their internodes short and 

 obtuse.
