THE MARINE MOLLUSCA AND BRACHIOPODA 

 OF THE ISLE OF MAN. 



Bv L. St. G. BYNE, >[.Sc., and ALFRED LEICESTER. 



(Read before the Society, February T3th, igoi). 



It has for some time occurred to us that a List of the Marine 

 MoUusca of the Isle of Man would be useful to workers, and we here 

 offer one as complete as we have been able to make it. It may 

 happen that. a few species have been inadvertently omitted, but many 

 trifling varieties have been purposely discarded. 



The Isle of Man, especially the area around the Calf, provides a 

 most excellent field for moUuscan work. Several rare species, e.g., 

 Peden incomparabilis (/'. testce), Cardium minimuin, Propilidhan ancy- 

 lo'ide, etc., may be obtained by dredging off Port Erin, where there is a 

 Biological Station under the direction of the Liverpool Marine 

 Biology Committee.' 



Good shore collecting is obtained at Port Erin, Port St. Mary, and 

 Fleshwick Bays, whilst dredging is most productive around the Calf 

 and off Port Erin, Bay Fine, Fleshwick, Contrary Head, and Spanish 

 Head. The Melobesia ground off St. Ann's Head is quite unpro- 

 ductive of mollusca. 



We have included several species not found by us up to the present 

 on the authority of previous writers on whom rests the responsibility 

 for the correctness of the occurrence and identification. Such are 

 Tellina tenuis, Paludestrina stagnaiis, {Hydrobia ulvce), Neptunea 

 antiqtia, (^Fusiis antiquus) var. striata, Clathurella {Defrancia) leufroyi, 

 and Otina otis. 



Yearly Reports upon the Marine Mollusca of the Island have been 

 compiled by one of us (A.L.), and have appeared in the Annual 

 Reports of the L.M.B.C., and in addition we have extracted informa- 

 tion from the following published works: — 

 Forbes, E. Malacologia monensis, Edinburgh, 1838. 

 Darbishire, R. D. The Testaceous Mollusca, Report upon the 



Fauna of Liverpool Bay, vol. i, p. 232-266, 1886. 

 Herdman, W. a. Notes on the Marine Invertebrate Fauna of the 

 Southern End of the Isle of Man, Tom cit., p. 318-341 [Mollusca, 



P- 337-339]- 

 Archer, F. Supplementary Report upon the Testaceous Mollusca 

 of the L.M.B.C. District, Op. cit., vol. 3, p. 59-75, 1892. 



I We desire here to record our indebtedness to the facilities given by this Institution and to 

 call the attention of other naturalists to them. Full particulars may be seen in the Reports of the 

 L.M.B.C. or may be obtained either from Professor Herdman or from the Curator of the Station.
