Crepidula fornicata L. on the Coast of Kent. — On April 9th I picked up 

 on the beach near Sandwich iwo specimens of Crepidula fornicata. One was dead, 

 the olher contained the animal, and was attached to a large Ckiysodo/iius antiijicus. 

 This Crepidula has been known for some time in the Esse.v rivers and, I believe, 

 in the Humber, but I am not aware of its having been found hitherto on the coast 

 of Kent. — J. E. Cooi'ER {Read before the Society, April 14th, 1909).
