Since the above was written I have learned that Physa Lordi (Baird) is 
found in the northern parts of the State of Michigan, but was at first described 
as Physa Parkeri; also, that Helix nitida, Muller, is common in the same State, 
and that it may prove common in Western Canada. 
Ihave also found Helix milium, Morse (April, 1880); and I find Helix 
minutissima, Lea, to be very common in certain localities. Both of these shells 
are new to the Canadian list, so far as I have been able to learn.
