118 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



(2) Specimens of Patella, showing the intrusion in varying 

 degree of sand grains between the mantle of the animal and its shell 

 and their incorporation into the substance of the shell by subsequent 

 deposit/ion of nacre, as well as individuals both of P. vulgata and 

 athletica that had been attacked by the boring Polychsete Worm, 

 Polydora ciliata, with one showing a very large baroque pearl. 



(3) Suites of Helix pisana, Helicella itala, and Hel. virgata, 

 including some of its varieties of banding, such as the rare var. 

 radiata and var. hypozona, besides a large, high-spired form, which 

 occurs on a wind-swept limestone cliff jutting out to sea, as well as 

 Hel. caperata and its var. ornata, and Cochlicella acuta. All these 

 Isle of Caldey helicoids are much darker than corresponding 

 individuals of the same species on the mainland at Tenby, or in the 

 British Isles generally. Possibly their dusky hue may indicate a 

 tendency towards Melanism. (4) Examples of Limncea pereger, 

 var. maritima, the only form of the species found on the island.
