Otina otis, Turton. 

 _ — - _ _ VI. — VIII. — — — _ 



Thompson (15) placed this species under the genus Velutina, but the 

 only British species (F. laevigata and V.2^licatilis) belong to quite a different 

 family. Prof. Harve}- was the first to discover 0. otis at Milltown- 

 Malbay on the Clare coast, and it has since been found on the Galway 

 coast (15). 



Foreign Distribution. — South coasts of England and Wales, Isle 

 of Man, Arran, N. B., north and west coasts of France. 



GenuS-AMPHIPEPLEA. 



Amphipeplea glutinosa, Miiller. 

 — — — — V. — VII. — — — — XII. 



This was not known to Thompson (15) as an Irish shell, but Mr. C. 

 Ashford (14) found it abundantly under the leaves of the Water Lily in 

 several parts of Ireland, and it is reported (5) to have been found in the 

 Grand Canal Harbour in Dublin. 



Foreign Distribution. — England, Sweden, north and south Ger- 

 many, north France, Galicia, and Syria. 



Genus — LIMN.SI A. 



Limnaea stagfnalis, L. 



— — — — V. VI. VII. — XI. X. — XII. 



This species has never been taken in the south-west or north-west of 

 Ireland, but in eastern Ireland, and especially around Dublin, it is fairly 

 common. 



Foreign Distribution. — England, south Scotland, Scandinavia, 

 Finland, Russia, Germany, France, Switzerland, Austria, Transylvania, 

 Turkey, Caucasus, north Italy, Siberia, and North America. 



Limnaea auricularia, T,. 

 I? — — — — V. VI. VII. VIII. — X. — — 



This species, like the last, is not common, and appears to be quite 

 absent from the south-west and north-west of Ireland, the only record 

 from the former region being doubtful (7). 



Foreign Distribution. — Great Britain, south Scandinavia, Finland, 

 Russia, France, Germany, Switzerland, Italy, Sicily, Spain, Portugal, 

 Algiers, Morocco, Cape Verd Islands, Siberia, and North America. 



Limnaea involuta, Harvey. 

 I. ___________ 



A short description of the anatomy of this interesting mollusc has 

 been given by Goodsir (4), but a more minute investigation is much 

 needed. It was first discovered in 1832 by Mr. Harvey, in Crimcaun 

 Lake, on the Cromaglaun Mountain, near Killarney. It has never been 

 found an}"\vhere else, but a closely allied species, Z. burnetti^ occurs in 

 Wales and Scotland. 



Limnsea peregfra, Miiller.

The fact that this species has been recorded from every district in 

 Ireland shows that it is very common, and it is so variable that scores of
