NATICA SORDIDA. 



To the Editors of the Annals of Natural History. 



Windsor Lodge, Monkstown, Co. Dublin, 

 Oct. 22, 1853. 

 Gentlemen, — I have much pleasure in being able to record an- 

 other habitat for that rare Mollusk Natica sordida, specimens of which 

 were obtained by me this summer ; they were taken off this coast by 

 trawling in about sixty fathoms. In company with the above shell was 

 found Fusil s proinnquus ; I have also noticed the same two !Mollusca 

 occurring together off" the Wexford coast, and my friend Dr. Melville 

 has likewise dredged the two species in close proximity off the Isles 

 of Arran, Gal way Bay. 



I remain. Gentlemen, yours truly obhged, 



William White Walpole.
