This is a very important monograph on the Genus Villosa in which this Genus is now restricted to the South-Eastern USA and other species previously in this Genus are now moved into several new Genera as well as into to previously existing Genera. As well as the new Generic clasifications, 2 new species are named and several new subspecies are name as well. About 20 species in all are now placed new taxonomic combinations. It is good to have this work in the now expanding amount of interest and research going into the freshwater mussels of the USA.
