 can be had only from Filey Bay, where the fisherman obtains it in a 

 somewhat unexpected manner. Armed with a long pricker with a 

 spade-shaped end, he walks backwards through the shallow water, and 

 noticing the presence of a razor shell, though it is out of sight, he 

 bores tentatively with his pricker, and getting right through the animal, 

 he gives a half-turn to his implement, which is too broad to slip 

 through the narrower diameter of the shell, and thus brings up the 

 impaled mollusc.
