PRIDEAUX''S HERMIT CRAB. l77 



In a subsequent note on the same subject, Mr. Thompson 

 quotes Dr. Coldstream, who, in a communication in the 

 " Edinburgh New Philosophical Journal,"" remarks, in treat- 

 ing- on the Actinia maculata obtained by him " at Torbay, 

 and in Rothsay and Kames Bays in Bute," that the shell 

 which it covered was always covered by a variety of the 

 Hermit Crab." It is also remarkable that " by Duges 

 the species have been found associated on the coast of 

 France." Whether this coincidence be accidental or other- 

 wise, it is difficult to decide without further observation ; 

 the facts, however, that Dr. Leach makes no mention of 

 its occurrence, and that Professor Edward Forbes states 

 that not a single specimen of the Actinia taken by him 

 in the course of a season was so associated, are much in 

 favour of their concurrence being fortuitous.
