Genital system, as figured by Moquin-Tandon, has a penis sac short, stout, with a very long, flagellate extension, on the middle of which en- ters the vas deferens; the retractor muscle is inserted at the com- mencement of the flagellum; the genital bladder is small, suboval, with a duct three times its length and very stout; at the entrance of this duct into the vagina there are, on both sides, a bundle of (four) multifid vesicles; quite near the common orifice there is a small, glob- ular sac, inclosing, in place of the usual dart, a small body fringed or digitated by four or five unequal obtuse lobes. TACHEA, Leach. Animal heliciform, mantle subcentral; other characters as in Patula. (See Bost. Journ. Nat. Hist., I, Plate VIII.) Shell imperforate, globose or subdepressed, white or yellow, orna- mented with distinct bands; whorls 5, the last convex, tumid, descend- ing at the aperture; aperture broadly lunate, obsoletely angular; peristome thickened, reflexed, its coluraellar margin constricted, cal- lous. A genus of Middle and Southern Europe; one species also common to America, perhaps imported by commerce. Our single species, T. hortensis, found only along the northeastern coast, and there usuallv restricted to the islands, agrees in its jaw with the other known Jaw of i\icin^jortcn<.-h: gpe^ies of the subgcuus.
