iMarine Concik^logy. — The Rev. F. H. Woods writos : — 

 Fortunately the storm on Saturday, which disappointed those 

 who had hoped to boat on the Mere, proved a lx)on to 

 Marine Conchologists, and quite unusual quantities of 

 shells were w^ashed up. Some of these are very rare on 

 the Yorkshire coast, as, for example, Artemis exoleta (see 

 list by Rev. W. C. Hey, ' Naturalist,' vol. x., p. 25), of 

 which there were quite a large number of complete specimens. 

 Curiously enough, lincta, which is fairly common on this coast, 

 was not found. Another very interesting find is Pecten egrinus, 

 of which two single valves were secured. To these should be 

 added specimens of Cardium norvegicum, which does not appear 

 to have been found by Mr. Hey himself, but adopted to his list 

 from the Scarborough Museum, where the specimen is marked 

 * Scarborough.' Another rather unusual feature was the 

 extraordinary quantity of the Common Cowry, CyprcBa europcea. 

 I picked up over fifty specimens in an hour's time on the shore 

 near Rolston. 



A full list of species is given below. It should be noted 

 that these do not include any microscopic forms, which appear 

 to be almost absent from this part of the coast, while abundant 

 at Filey and northwards. It is, of course, uncertain how far 

 this list represents the marine conchological fauna of the dis- 

 trict, as many of the shells may have been driven some distance 

 from the north.
