Characters and Description. — Shell straight, elongated, with a smooth surface, with 
the posterior half conical and pointed, generally caducous in the adult. The anterior 
half is swollen medianly, but constricted behind the aperture. A partition, concave in

this the truncation is formed. The transverse section is circular, except towards the 
aperture, where it is a little compressed, and appears somewhat reniform. Behind
