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, Hiucks, would seem to have no other habitat; and 

 in the only known locality for it^ the shallow water of£ 

 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.
