266 The Irish Naturalist. 



I^AND AND Freshwater Moi.IvUSCA. 



The number of members particularly interested in the investigation of 

 the land and freshwater moUusca of the district covered by the 

 excursion was practically limited to myself, and Messrs. Welch and 

 Collier, but several others so far interested themselves as to pick up such 

 specimens as they came across whilst engaged in their own special 

 pursuits, and handed them to me. In this way much valuable 

 assistance was rendered, for which I would here take the opportunity 

 of thanking one and all. 



From the diversified character of the ground over which our researches 

 extended, a good list was hoped for, but, with the exception of Lough 

 Corrib, the various sheets of water proved rather unproductive. The 

 failure to find the rare Vertigo Moulinsiana was a grievous disappointment, 

 but .circumstances prohibited any lengthy search in its recorded 

 localities, to which moreover we had no precise clue. 



On the occasion of our trip to Oughterard the courtesy of a local 

 gentleman, Mr. Henry Hodgson, J. P., of Currarevagh, in kindly 

 placing a couple of boats at our disposal, enabled Messrs. F. J. 

 Bigger, R. Welch, E. Collier, and myself to cross over to Inchangoil, 

 and he otherwise extended his hospitality. This visit was especially 

 interesting, both from the historic associations connected with the place 

 and from the fact that it was very probably the first time a conchologist 

 had ever set foot on this beautiful islet, which proved a good collecting 

 ground. 



On the breaking up of the party, eight of us spent a few days at 

 Roundstone, and whilst some visited Inis MacDara, and other places, 

 the rest investigated the shores and sandhills of Dog's Bay. (For 

 particulars of the interesting deposit of semi-fossil land shells found 

 there see note at end of list.) On the return journey a break was made 

 at Athlone, where the night was spent, and next day the party visited 

 Clonmacnois. The many interesting finds made during this " extension 

 trip" are included in the subjoined list— in which I have chiefly followed 

 the nomenclature and classification used by Dr. Scharff in his " List of 

 Irish Mollusca." In all cases where a particular species was only taken 

 by one individual his name follows in brackets. 



Vitrlna pelluclda, Mull.— Gentian Hill, near Galway ; Aran ; Inch- 

 angoil ; and Inis McDara. As is generally the case during the summer 

 months only dead specimens were obtained. 



Hyallnia cellaria, Mull. — Common everywhere. 



Hy. draparnaldl, Beck.— Very fine near Kilronan, Aran; and 

 Clare-Galway Abbey. 



Hy. alliarla, Miller.— Clare-Galway Abbey; Inis McDara; and 

 near Athlone. Uncommon. 



Hy. nitidula, Drap.— Common at Clare-Galway; Inchangoil; Innis 

 McDara ; and Clonmacnois. 



Hy. pura, Alder.— On Inchangoil, the only locality noted, the brown 

 variety is fairly plentiful under moss-covered stones in the graveyard. 



Hy. radlatula, Alder.— Several fine specimens under stones on 

 shore of Lough Corrib, between the Abbey and Castle at Annaghdown. 



Hy. crystalllna, Mull.— A small compact form at Gentian Hill; 

 Ballyvaughan ; and Inchangoil. Not plentiful.
