ANURIDA. 363 



III. GEOGRAPHICAL DISTRIBUTION. 



Anurida maritima has been recorded from a number 

 of localities scattered all around our British coasts. It 

 appears to be abundant in the neighbourhood of Penzance 

 and Land's End (Marquand, 75), it also occurs at 

 Plymouth (Parfitt, 80), and the present writer has met 

 with it sparingly at Torquay. On the coasts of Wales it is 

 known from Gower, Kevin and Llandudno,* and it is also 

 common on the broad stretches of sand in the neighbour- 

 hood of Rhyl. On the west coast of Scotland it is 

 described as being common among seaweed-covered rocks 

 at Peaton, Loch Long (Evans, 60) ; it is also found on the 

 shores of Ayrshire and Buteshire (Boyd, 52). On the east 

 coast Lubbock (Lord Avebury) mentions it from St. 

 Andrews, and it is plentiful about the shores of East 

 Lothian at Aberlady and North Berwick (Carpenter and 

 Evans, 57). In the Isle of Man it is abundant among the 

 rocks on the north side of Port Erin Bay, and can also 

 be met with at Poolvaish near Castletown. In Ireland it 

 occurs on the east, south and west coasts (Carpenter and 

 Evans), and Lubbock mentions having received it from 

 Kinsale. 



On the continent of Europe Anurida is plentiful in 

 France at Treport, Havre, Boulogne and ether places, 

 together with the Channel Isles. It has also been recorded 

 from Holland, Belgium, Denmark, Heligoland and 

 Scandinavia. 



In North America! it is reported from the Atlantic 

 coast from Cape Ann, Annisquam, Long Island, New 



* For these localities, the writer is indebted to Dr. I). Sharp, P.R.S., 

 for Gower, and to Mr. F. A. Potts for Nevin and Llandudno. 



f Packard (79) states that the American examples of Anurida 

 have been examined by Lubbock and found to be identical with the 

 European form.
