IQO MARSHALL : ON SOME NEW BRITISH SHELLS. 



Mr. B. Sturges Dodd is to be congratulated on his keen- 

 ness and enthusiasm in adding this minute species to the British 

 fauna, a preliminary notice of which appeared in the " Notting- 

 hamshire Weekly Express " at the time of discovery, and a short 

 paper on which was read before the Nottingham Naturalists' 

 Society at their meeting of December 14th last. 



Scalaria pseudoscalaris, Broc PL I, fig. 4. 



Another species that may now be considered conclusively 

 established as British is Scalaria pseudoscalaris^ Broc, as six 

 specimens have been found in recent years from three widely 

 different localities — Scilly, North Devon, and Kent. Miss 

 Fairbrass, of Faversham, an old and trustworthy correspondent, 

 is the discoverer of all six specimens, three of which were found 

 at Pegwell Bay in Kent, one at Ilfracombe, and two at Scilly. 

 In all three cases they were found on the shore with our 

 common S. communis. 



It is only quite recently that Miss Fairbrass submitted them 

 to me, although they have been in her possession and noted as 

 distinct for some time. She wrote to me : — " I picked up these 

 Scalaria at Pegwell Bay and I placed them with the 6". communis 

 I also found there, but always thought them very different, and 

 hoped for an opportunity of sending them to a conchologist 

 who could inform me if they were distinct." I may add that 

 she is always very particular as to her localities, her shells as 

 she collects them being entered and numbered in books. It is 

 a shell not easily recognisable from our 6". communis, except to 

 one acquainted with the European species, especially after 

 being rolled on the beach. The differences are slight except 

 in one important particular — the last whorl is encircled at the 

 base by a prominent white ridge, giving the appearance of an 

 additional whorl having been broken off at that part.
