 in the neighbourhood, but only met with some of the common 

 kinds.

NOTES ON THE MOEEUSCA OF CO. EEITRIM. 



BY P. H. GRIERSON. 



When I began work in April, 1899, I knew nothing about the 

 subject, and sent all my specimens to Dr. Scharff for iden- 

 tification, but these few notes may be of interest. 



Co. Leitrim is a long rather narrow county with a low rocky 

 coast-line of nearly three miles between counties Sligo and 

 Donegal, and extending in a south-easterly direction for 

 about fifty miles. It is chiefly limestone, covered in most 

 places with deposits of drift. There are some Coal-measures, 

 which proved very unproductive from a conchological point of 

 view. The northern part is very mountainous, and so is the 

 south-eastern shore of L,ough Allen, where Slieve Anierin 

 rises to over 1,900 feet; the rest of the county is undulat- 

 ing with low hills. Lakes and rivers are very numerous, 

 especially in the southern part. The River Shannon bounds 

 it for perhaps twenty miles on the south-western side. A very 

 considerable portion of the county is covered with bog. 



During a ramble one afternoon between Mohill and Feenagh 

 I found the following slugs — most of them were in Feenagh 

 Churchyard: — Avion atcr^A. subfuscus,A. hortensis, A. circum- 

 scriptus, Liviax maximus, and Agriolimax agrestis ; later on near 

 Cloone I found Avion minimus. Vitrina pellucida was common 

 in the districts of Manorhamilton and Cloone. Of the 

 Hvali?iice I found H. draparnaldi and H. crystalline/, at Manor- 

 hamilton, H. alliaria and H. nitidula at Dromahaire, H> pura 

 at Glencar, H. fulva at Mohill, H. nitida near Dromod, at the 

 Shannon ; H. ccllaria is common in many places. Of the
