Isis (?) ELONGATA. (Esper.) 



I. rubra, laxe ramosa, ramis teretibus, axis articulis lapideis valde 

 elongatis, striatis, internodiis brevissimis. 



Red, lax ramose, branches terete ; calcareous joints of the axis much 

 elongate, striate ; internodes very short. 



This is a very neat and slender species, with long joints, and short 

 internodes. It has the general habit of a Mopsea. According to 

 Risso's figure, the polyps are long exsert and not retractile, forming 

 thus slender elongate verrucse. The closed polyps are represented as 

 mostly reversed on the stem, nearly as in the Primrioa. The cortex 

 becomes dark brown on drying.
