This species is on the borderland 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 delicately 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. (himerodes = pleasing, desirable).
