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 wasa 
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 specimenthough 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.
