Although very generally distributed throughout the globe, and 

 perhaps more so than most of the Polyzoa, it appears extremely 

 doubtful whether this species really belongs to the British Fauna. 

 The only British specimen I have seen or been able to hear of, is 

 that in Dr. Johnston's collection now in the British Museum, 

 and found by Mr. Bean at Scarborough. The other forms in- 

 cluded under the same name by Dr. Johnston, as well as those 

 collected by Lieut. Thomas at Copinstra and off Tynemouth, all 

 belong to Cellularia peachii : so that, unless the specimen men- 

 tioned by Dr. Fleming, as collected by Miss Blackburne on the coast 

 of Cheshire, should really belong to A. neritina. it might be con- 

 cluded that Mr. Bean's specimen was one accidentally introduced 

 by some vessel from abroad.
