164 The Irish Naturalist. August, 



But Mr. Clarke was not unmindful of the existence of other 

 insects, and records (p. 47) having taken the rare beetle Carabiis 

 7iitc?is off the bog of ClonbuUock. Even microscopic creatures 

 were not beyond his ken, for he tells us of the occurrence of 

 Hydra viridis, Cyclops qtcadrico7iiis, and Cyclops castor in the 

 neighbouring ditches (p. 128). 



When we come to his special subject, the land and fresh- 

 water Mollusca, his remarks are naturally of particular interest. 

 Pla7iorbis comeus he refers to as being very plentiful in the 

 townland of Clononne3% and he also mentions Helix fusca, 

 Helix lamellata^ Acme lineata^ Coecilianella acicicla, Biilivmms 

 obscurus^ and other uncommon species as occurring in the 

 neighbourhood. 



Ornithologists will be interested to learn that on Mr. Clarke's 

 authority the Crossbill was seen near J^a Bergerie in the spring 

 of 1838, one gentleman having shot no less than seven of them.

NOTES ON THE MOLLUSCA OF NORTH CORK 



AND WATERFORD. 



BY p. H. GRIKRSON. 



The following notes were made during the summer and 

 autumn of 1902 and summer of 1903, in the northern portion 

 of the Co. Cork and in Co. Waterford, over an area extending 

 across the greater portion of the south of Ireland, and varying 

 greatly in its soil and geological features. 



I have confined m3^self simply to giving the name of the 

 nearest town to where the specimens were taken, with the 

 number of the one-inch Ordnance Survey map after it. I 

 have followed Dr. ScharfF's nomenclature as given in hish 

 Naturalist^ 1892. 



I am much indebted to Messrs. L. E- Adams and R. Welch 

 for help — the former for naming slugs, &c., and the latter for 

 sending me the names oi Hyalinics and Fisidia. The trouble- 

 some immature Hyalinice Mr. Welch submitted to Messrs. 

 L. E. Adams or G. W. Taylor, and the Pisidia to Mr. 

 Oldham.
