Found quite generally in the Eastern and Middle States. Melaniid^. It should be noted of this family that it contains many genera and hundreds of species. Almost every river drainage system of the world has either distinct or closely allied forms; those of the United States being the Strepomatidae, of which there are many local genera, the most compion of the Eastern and Middle States being the Goniobases and Anculosa of the Hudson, Susquehanna, Delaware and Potomac basins. For brevity these only are described, the others are closely related similar forms. GoNioBAsis. This genus has most beautiful conical or fusiform shells, showing faint lines of growth and often series of longitudinal ridges on the seven to ten whorls. Occurs quite generally in flowing waters.
