154 CAMPANULARIID^. 



(Dr. Collingwood). Dr. Collingwood writes, "The most 

 common and characteristic zoophyte (next to Tubularia 

 indivisa, perhaps) of our shores. It is interesting as 

 being a favourite feeding-ground for some minute forms of 

 Nudibranchiata (e. g. Eolis despecta, E. exigua, E. con- 

 cinna)." It is in the greatest profusion in the tide-pools 

 of the Dingle Rocks, where it attains a large size. Also 

 abundant at Egremont, Hilbre Island, and other places.
