This species is on the border-land between the subgenera 

 Glyphostoma and Cythara. A pure white, extremely delicate 

 little species, subvitreous, fusiform, with seven whorls, two of 

 which are glassy and apical, the remainder being all very deli- 

 cately ribbed, with spiral lirae, the interstices longitudinally 

 striolate. At the sutures and the angle of the whorls there is a 

 pale ochre band, again appearing, but almost obsoletely, in 

 the middle of the last whorl. It is very conspicuous, however, 

 just at the back of the outer lip. The mouth is narrow, outer 

 lip thickened, columella simple. Many specimens. (i/*ep«S»/s,
