PLATE XLVIT. 



According to Dr. Lister this species is a shore shell, and found very 

 frequently in the shallows of Lancashire, and near Filey in Yorkshire, 

 &c. It is also found at Scarborough, Dorsetshire, Devonshire, and 

 Cornwall. 



It is an elegant shell, the outside being beautifully marked with 

 numerous delicate striae like strokes of engraving, and tinged with a 

 fine rose or flesh colour. Some specimens are almost white, or white 

 with transverse bands of deeper red, and the margins yellow. With- 

 in, the red colour is much more vivid than the outside.

 Da Costa has placed this species in the Cardium genus, and indeed 



with much propriety ; though Linnaeus arranges it amongst the 

 Tellens. It has a tendency on one side to flexure or slope like the 

 Tellens, but the central and remote lateral teeth we think mould re- 

 move it to the former genus.
