 Helix mondon fraterna Say. 

 Helix leaii Ward. 

 Helix tridentata Say. 

 Helix palliata Say. 



Helix virgata Da Costa. A single well marked example of this 

 species, apparently of the variety called ''alba" by Taylor, occurs 

 in the collection with the following label: "From Dr. Clark of 

 Flint, Michigan, where he says it was found." Dr. Clark was a 

 well known physician of Flint in times past ; but as both he and 

 Dr. Lathrop are dead, it is not probable that any further informa- 

 tion in regard to the circumstances under which this shell was 

 found can be had. The specimen though mature, is not quite fresh, 

 and as the body whorl was filled with hard packed fine sand it 

 seems very probable that it was imported in the earth about some 

 foreign plants. 



Vallonia pulchella Mull. Determined by Dr Sterki. 

 Strobilops labyrinthica Say. 



Pupa corticaria Say. These are the first specimens seen from the 

 eastern part of the State.
