CONTRIBUTIONS TOWARDS 



A LIST OF THE MARINE MOLLUSCA 



OF KILLALA BAY, IRELAND. 



By miss amy WARREN. 

 (Read before the Concliological Society, October 5th, 1892). 



I HAVE been induced to prepare the following List, although 

 only the result of shore-collecting, as the bay has never been 

 investigated by the collector's dredge ; so that my more prosaic 

 finds will give some idea of what the locality produces, especially 

 as it is the result of several years' research. Also, I have never 

 been content with the mere shell-drift of the sandy shore, but 

 have had many a day's hard work amongst the rocks — always 

 the most interesting, and on this coast sometimes exciting, as 

 there is often an idea of danger from the incoming rollers of 

 the Atlantic. 



Killala Bay, on the west coast of Ireland, opens to the 

 north, and from Kilcummin Head (Mayo) to Kinnasharragh 

 Point (Sligo) is about eight miles. The Island of Bartra (2I 

 miles long), which is all sand-hills to the seaward, lies partly 

 across the head of the bay and forms a natural break-water, 

 and the Enniscrone sand-hills stretch out two miles and nearly 

 meet those of Bartra, the river Moy channel dividing them. 

 Between these and the mainland are extensive sand-flats, and 

 here the estuary shells are to be found. The shore under 

 Kilcummin Head is very rocky, as is also the coast north of 

 Enniscrone. This description of the locality will shew what to 

 expect in the following List. 



The arrangement I have followed is that of Jeffreys' ' British 

 Conchology.' 



I have to acknowledge the great kindness of Mr. J. T. 

 Marshall, of Sevenoaks, Torquay, who has always responded 

 most willingly to my numerous appeals for help in identification.
