LIVID SWIMMING-CRAB. Ill 



Britannise" was published. It is not mentioned by Mr. 

 H. Goodsir as occurring 1 within his notice on the Scottish 

 coast ; nor does Mr. Couch give any account of its oc- 

 currence in Cornwall. In Ireland, however, according to 

 Mr. W. Thompson's statement, it has occurred repeatedly ; 

 but as it appears to me that faded specimens of P. 

 marmoreus might be easily mistaken for this species, it is 

 always desirable that they should be compared with those 

 well distinguished specimens which exist in the British 

 Museum. The following is Mr. Thompson's notice to 

 which I have referred. " Templeton mentions it as found 

 by him ' on the shore at Dunfanaghy.' We have dredged 

 it on more than one occasion in Belfast Bay, and have 

 obtained it on the beach of Carnlough, county of Antrim. 

 In Mr. R. Ball's collection, are several specimens which 

 were dredged in Dublin Bay." It is mentioned by Milne 

 Edwards as occurring on the French coast.
