Abstrakt:	We documented the currently known distribution of the Asian snail Bellamya (=Cipangopaludina) chinensis in Minnesota, along with another viviparid snail, Viviparus georgianus, a North American native whose range has expanded. We also recorded the first known occurrence of Bellamya japonica in Wisconsin. Bellamya chinensis and V. georgianus occurred predominately in lakes within the Minneapolis/St. Paul metropolitan area and the lakes region of northcentral Minnesota. Both species are now established in the three major watersheds that drain Minnesota. We collected Bellamya japonica at six sites in the Namekagon River, part of St. Croix River system in Wisconsin.
