odour of roses and geraniums ;" whilst Ellis bluntly calls 

 it "fishy." 



The flat frond of F. foliacea * offers an excellent site 

 for the colonies of the smaller Polyzoa and Hydroida; 

 and many species are commonly found associated with it 

 amongst the rest, Scrupocellaria reptans and S. scruposa, 

 Crisia eburnea, Bugula flabellata, Sertularella rugosa, &c. 



The rare and interesting Hydroid Hydranthea mar- 

 garica, Hincks, would seem to have no other habitat ; and 

 in the only known locality for it, the shallow water off 

 the Capstone at Ilfracombe, almost every tuft of the 

 Flustra which comes up in the dredge is covered with its 

 delicate network and flower-like polypites. 



Sir John Dalyell has studied the embryos, and states 

 that he has known ten thousand to be liberated from a 

 specimen in the course of three hours ! 



This species is one of the commonest of sea-side objects, 

 and may generally be met with on any sandy beach.
