This species is probably related to P. auraniana and its 

 allies. It has been erroneously placed in the synonymy of 

 P. otaheitana by G-arrett (Journ. Acad. N. S. Phila. ix, 

 p. 47).

The shell is long ovate, moderately strong, white under a 

 thin cuticle which is gray on the spire and base, yellowish- 

 brown in the middle part of the last whorl, where there are 

 very faint traces of spiral lighter and darker bands. The spire 

 is rather long, whorls convex; suture well impressed. Just 

 above the suture may be seen an inconspicuous ridge or angle 

 the periphery of the penultimate whorl. The embryonic 

 sculpture is worn; subsequent whorls have very even and 

 regular spiral striation, which may be slightly weaker on the 

 upper part of the last whorl. Last whorl is convex at first, 

 on the last half becoming flattened laterally; very convex, 

 sack-like, at the base. The umbilical fissure is short but deep. 

 Aperture slightly oblique, ovate, small, white inside. Peris- 

 tome well expanded, thickened within, white, columellar mar- 

 gin dilated above, and slightly grooved where it joins the 

 preceding whorl. Parietal callus transparent. 



Length 19.7, diam. 10.2, aperture 10 x 7 mm. ; whorls 51/4.
