Punctum azoricum spec. nov. is described from the Azorean Island of São Miguel. This species was probably previously reported as Punctum minutissimum (Lea). Deroceras agreste (L.) is removed from the Azorean list. Attention is drawn to the possible occurrence of aphallic specimens in Deroceras panormitanum (Lessona & Pollonera).
