*) P. o. may be a variety of P. quadridens Pfr.: but when full 
grown it is oval; the spiral ribs on the last whorl are broad and approxi- 
mate, and on the whole shell they are smooth, without the irregular mi- 
eroscopie granulations of P. quadridens: the color is yellowish brown or 
waxen: the aperture is similar to that of Dr. Pfeiffer's species, but the tooth 
of the right side is less conspicuous. — Length 0,12; breadth 0,09 inch.
