The Irish Land and Freshwater Mollusca. 89, 



Limas: flavus, L- 



I. II. — IV. V. — — — IX. — XI. — 



Although abundant in Dublin cellars, this species has very rarely oc- 

 curred to me in the country, and I have never met it on the west coast. 

 Thompson (16) recorded it from the north, Messrs. Taylor and Roebuck 

 (14) from Waterford and Cork, and Mr. Barrett-Hamilton sent me speci- 

 mens from Wexford. 



FoRKiGN Distribution. — Great Britain, throughout Continental 

 Europe, Asia Minor, Algiers, Sicily, Sardinia, Azores, occurs also in 

 many localities on the east coast of North America and Brazil, as well as 

 in Australia and New Zealand, but it is believed to have been introduced 

 into these regions. 



Limax marginatus, Miiller. 



I. II. III. IV. V. VI. VII. VIII. IX. X. XI. XII. 



The older name has been retained here, although in most of the British 

 works this species is described as Z, arborum (Bouch.-Ch.) It is one of the 

 commonest of our slugs, especially on the west coast, where it associates 

 with Geonialacus maculosus. It_ occurs also on the Skellig rock and the 

 Aran Islands. 



Foreign Distribution. — Great Britain (including Shetland Islands 

 and Faroe Island), Scandinavia, Germany, Austria, France, Italy, Sicily, 

 Spain, Portugal, and the Canary Islands. 



Genus— AGRIOLIM AX. 



Agriolimax agrestis, L. 

 I. II. III. IV. V. — VII. VIII. IX. X. XI. XII. 



This slug is extremely common ever5rwhere in Ireland. It varies con- 

 siderably in colour from pure yellowish-white to chocolate-brown. A 

 bluish form has also been taken. 



Foreign Distribution. — Great ' Britain and throughout continental 

 Europe, Asia Minor, Persia, Siberia, Japan, Iceland, the Azores, Canary 

 Islands, Madeira, Morocco, and Greenland. It has probably been intro- 

 duced on the east coast of N. America, in Brazil, South Africa, and New 

 Zealand. 



Agriolimax laevis, Miiller. 



I. — — IV. V. — VII. VIII. _ — XI. — 



This is one of our rarest slugs. It was first discovered by Mr. H. B. 

 Rathborne in the Dublin mountains, and I have since met with it in 

 Connemara, Killarney, Glengariff, Greystones, and in Knockdrin de- 

 mesne, near Mullingar. Mr. J. N. Milne has sent it to me from Culmore, 

 near Londonderry. 



Foreign Distribution. — Great Britain and throughout continental 

 Europe. A closely allied species, A. campesiris, is found in N. America. 



Genus— AMALIA. 

 Amalia Sowerbyi, Fer. 



I. II. — IV. V. — — VIII. IX. — XI. XII. 



When I referred to this species on a previous occasion (12), I believed 

 A. carinata. Leach, was the correct name, but as Mr. E. Collinge pointed 

 out to me. Leach's work was not for sale until many years after Ferussac 

 had published a description of the species. 



In Dublin this species is very common, but in the north it seems to be 

 much rarer, as Thompson does not record it. It has only recently been 

 obtained in Antrim (17), and by Mr. J. N. Milne, near Londonderry.
