lOO WARREN : MARINE MOLLUSCA OF KILLALA RAY, IRELAND. 



M. bidentata (Mont.). Occasionally procured in the debris 



amongst the rocks at Carrahubbuck. 

 M. ferruginosa (Mont.). Valves very common in shell-sand, 

 and after a gale in February, 1892, I found two perfect 

 specimens at Enniscrone. 

 M. dawsoni Jeff. A valve of this very rare species was 

 detected by Mr. Marshall in drift from Bartra Island. 

 Other valves were dredged in deep water off Donegal Bay 

 in the 'Porcupine' Expedition. 

 Lasaea rubra (Mont.). Very abundant, living amongst the 

 crowded mussels on the rocks and in the tufts of Lichina 

 pygincea. 

 Kellia suborbicularis (Mont.). In the Saxicava burrows in 



the limestone. 

 Lucina borealis (L.). A few perfect and full-grown shells on 



tlie sandy shores of Bartra and Enniscrone. 

 Axinus flexuosus (Mont.). At Bartra, frequently in shell- 

 sand, but never alive. 

 Cyamium minutum (Fab.). 

 Cardium echinatum L. Common, cast up alive on the 



sandy shores after storms. 

 C. exiguum Gmel. A few good specimens at Enniscrone. 

 C. fasciatum Mont. Valves at Enniscrone. 

 C. nodosum Turt. 

 C. edule L. 



C. norvegicum Speng. In January, 1878, an unusually 

 severe gale displaced many sand-banks in the bay, causing 

 them to yield up their treasures. The 'ill wind' in this' 

 case brought the treasures to land, and several very fine 

 specimens of this handsome Cardium were procured at 

 Enniscrone. 

 Cyprina islandica (L.). Rare on this coast. Single valves 



occasionally. 

 Astarte triangularis (Mont.). Enniscrone. 



J.C., vii., Oct , 1892.
