344 — Genus Miriopyrcjus, Meek. Founded upon a minute, smooth, sub- 



cylindrical shell, with a rather obtuse apex, and a subrhombic 

 aperture. It is much like Pijryuld, but differs in not having 

 its axis perforate, while its whorls are without carinaj, though 

 they are prominent and obtusely subangular below the middle. 

 Occurs with fresh-water forms. Type Melania viinutula, Meek 

 & Hayden, Proc. Acad. Nat. Sci. June, 1856.
