This species is on the border-land between the subgenera 
Gly phostoma 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 lire, 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.  (tpepwdys, 
pleasing, desirable).
