This is a thin, somewhat ventricose species, with the winged 

 varices peculiar to the group shorter than in the allied forms. The 

 whorls are variegated with deep chestnut-hrown, and there is a faint 

 white transverse line in the middle of the last whorl.

 trifariam varicosa ; spira acuta ; anfractibus 6, planis, postice

P. testa ovato-fusiformi, pallide fusca, trifariam varicosa; spira
