NOTES ON THE SLUGS AND LAND SHELLS 

 OF ICELAND. 



HANS SCHLESCH. 



Hellcrup, Denmark. 



In its Land Mollusca the Iceland fauna is very poor and 

 possesses the characters of that of Scandinavia. Only two 

 species are Arctic forms, viz., Pupa arctica Wall, and Succinea 

 groenlandica Beck. Messrs. F. H. Sikes (Sevenoaks), and 

 Bjarni Saemundsson (Reykjavik), have added a good deal 

 to our knowledge of this fauna, and have kindly provided me 

 with lists of their finds. As the island becomes more system- 

 atically explored, however, it is probable that additional 

 species will be found. The collections of Mr. Bjarni Ssemunds- 

 son are placed in the Reykjavik Museum ; of Mr. F. H. Sikes 

 in the British Museum, and my own in the Hull Museum. 



The abbreviations of the collectors' names are the same as 

 in my paper on ' The Icelandic Forms of Limncea ' ( The 

 Naturalist, 1917, pp. 257-259).
