NOTES OF CERTAIN TERRESTRIAL AND FLUVIATILE 

 MOLLUSCA FROM GLENGARIFF, CO. CORK. 



By Staff-Surgeon K. H. JONES, M.B., F.Z.S., R.N. 



(Read before the Society, Sept. 13, 1911). 



The specimens referred to in the following notes were collected by 

 the writer in the vicinit}' of Glengariff, Bantry Bay, at the end of 

 March and the beginning of April, 1911. 



The terrestrial species are not of particular interest, but some of 

 the fluviatile, and especially those belonging to the genus Pisidium, 

 require to be carefully considered if only on account of their geo- 

 graphical distribution. It is perhaps doubtful whether Pisidium 

 hibernicuui and Liinncea iiwoluta have previously been collected so 

 early in the year. 



Under the head of each species mention is made of the peculiari- 

 ties of its habitat, if any, and of the position of the same in relation 

 to Glengariff. 



For the identification of the species of Pisidium, Mr. B. B. Wood- 

 ward is responsible. The terrestrial species were submitted to Mr. 

 A. W. Stelfox, of Belfast. 



The following species were met with : — • 



Hyalinia nitidula. 



H. pura. 



H. radiatula and var. viridescenti-alba. 



H. crystallina. 



Zonitoides excavatus and var. vitrina. 



Pyramidula rotundata. 



Cochlicopa lubrica. 



All the above species were found abundantly in the woods imme- 

 diately behind the Eccles Hotel. 



Helix aspersa of course was plentiful and nearly always very 



thin in the shell.
