P. 81. P. NITIDUS. In Miiller's own collection at Copen- 

 hagen specimens of this and the last species are intermixed, 

 and are named in his handwriting " P. nitidus" I am now 

 inclined to consider this 'the Helix complanata of Linne ; but 

 it may be more convenient to continue the error than to make 

 so many resulting changes. It is the H. fontana of Lightfoot. 

 P. riparius of Westerlund is a small variety.
