Naturalists,

The publication on this is now available on line - and any of the 
provincial museums would be glad of specimens or photos documenting that 
it is "is clearly more widespread in the region."

gives an account of the St John River discovery and our experience with 
the species in Ontario, and

an account of the ones near home.

=============================================================

Abstract: The Chinese mystery snail, Cipangopaludina [=Bellamya] 
chinensis, is documented for the first time in the Saint John River, New
Brunswick, a watercourse which drains the largest watershed in Atlantic 
Canada. This is the first non-native mollusc known to be established
in the Saint John River system. Although significant ecosystem effects 
of the species seem unlikely, possible introduction of C. chinensis via
boat traffic emphasizes the need for boater education combined with 
monitoring of the Saint John River system for potentially more
troublesome non-native species, including the zebra mussel, Dreissena 
polymorpha. Review of published records and museum collections
for Atlantic Canada show C. chinensis has been reported from 13 
freshwater wetlands and waterbodies in New Brunswick, Nova Scotia and
Newfoundland since 1955. The species remains extant in at least 10 of 
these sites and is clearly more widespread in the region than the single
previously published report would suggest.
