Fur pur a lapillus, L. 



A narrow elongated form occurs rarely at Llandudno 

 (B,T.) : an instructive comparison is to be drawn 

 between the ordinary clean, well-coloured Purpuras 

 so common at Llandudno by the pier, and a very 

 large solid, muddy-looking form which occurs at 

 extreme low water on the '' Conway shore " (so-called) 

 along the Morfa. By the pier shells of a rather un- 

 usual colour, pinkish mauve, are not uncommon, 

 var. imhricata, Lam. In the McAndrew Coll. (Camb. 

 Univ. Mus. of Comp. Anatomy) may be seen a mag- 

 nificent suite of some 40 specimens of this var., 

 beautifully frilled. They were dredged in Khoscolyn 

 Bay, Anglesea, in 4 — 7 fms.
