Left to right, top row to bottom, shells of Hydrobia totteni (A), H. salsa paratype (B), H. truncata paratypes (C, D), H. truncata from Stone Harbor (E-I), H. truncata from Salt Pond (J-L). The shell length of A is mm; other shells are drawn to the same scale. Hydrobia totteni. The shells vary from ovate to ovate-conic (Fig. 7A) and have a high rate of whorl expansion as discussed for H. salsa (Fig. 8). They vary from uneroded to severly eroded so that often only three whorls are seen; the degree of erosion var
