THE CONCHOLOGIST. 



FOR 1891. 



MARINE SHELLS OF NORTH WALES. 



r.v Rev. Cari.etoN' Crefxe, M.A. 



THE following list is the result of three 

 visits made in 1881, 1883, and 1889. 

 I have availed myself of the aid of other 

 collectors in compiling it, and have to 

 acknowledge especially the assistance of 

 Miss E. Harrison, of Hendremynach, Bar- 

 mouth ; Rev. H. Milnes, of Winster ; and Miss 

 Edwards, of Bury St. Edmunds. The records 

 contained in Jeffrey's " British Conchology " 

 and other works have been incorporated for 

 the sake of completeness, and are printed 

 in italics. The reputation of Mochras as 

 a hunting-ground appears to have declined 

 lately, and I am informed that at Barmouth 

 the most interesting shells have disappeared 

 since the laying down of the new sewer-pipe. 

 Under the term. Barmouth in this list is in- 

 cluded all the coast south of Mochras and 

 north of Towyn. The only place where 

 shells were found at my last visit was at 

 the mouth of Tal-y-bont stream, about two 

 miles north of IJanaber Church. There may 

 be many out-of-the-way places yet to be 

 explored, especially in the Lleyn promontory 

 of Carnarvonshire ; but the following list alone 

 shows, I think, that North Wales possesses 

 a great range of species, and deserves a high 

 place as a region of conchological interest.
