with the possible exception of Hdicdla barbara and Hygromia hispida. The 

 latter must occur somewhere in the area, but is evidently not common ; and 

 the former, though undoubtedly absent from the sandy shores about Curraun, 

 probably occurs further north along the shore of Blacksod Bay. The fresh- 

 water list is, I think, possibly complete or almost so. The letters B, C, G-, and 

 M following the name of a species denote that it was found at Ballaghcragher 

 Bay, Curraun, Gleneastle, or Carrowmore Lough respectively. Those not 

 followed bv anv letters are o-enerallv distributed.
