Clare Inland Survey — Land and Fresh-water Mollusca. 23 35 



barren beyond description. Except on Tory Island, in Donegal, and on the 

 outer islands of the Shyrgaard of Norway, I have never seen such desolate 

 tracts of land. Fresh-water habitats are frequent, but yielded no species of 

 special interest, with the single exception of Pisidium hibernicum. I have to 

 thank G. P. Farran for an unpublished list of mollusks collected by him on 

 the island during the years 1900 and 1901. This contains twenty-three 

 species, five of which were only represented by dead examples found in the 

 " shell-pockets " on the sand-dunes. The total list of species known to live 

 or to have lived on Inishbofin is as follows 1 : —
