This species was referred by Carpenter and Tryon to Zuspira pallida Broderip 
and Sowerby, but this ascription is absurd, since the latter species is without the 
Sutural channel and has a decidedly different outline, besides being a very much 
larger shell,

Plate 11, figure 7. 
Shell small, white, smooth, covered by a conspicuous, brownish periostracum ; 
Whorls about four, the nucleus eroded; suture distinct, deep; the whorls rather 
full at the shoulder, giving a somewhat elongated aspect to the shell, rounded, 
the last much the largest; sculpture of incremental lines rather feeble and irreg- 
ular, and, on the spire, numerous, not very regular, fine wrinkles radiating from 
the suture and becoming obsolete near the periphery, but absent from the last 
Whorl; there are also a few faint, irregular, spiral markings, perhaps pathological ; 
aperture ovate, outer lip thin, simple; body with a thin, whitish callus thicker on 
the Pillar, which is arcuate, slightly reflected and with a very narrow umbilical 
chink open behind it; operculum dark brown, horny, with about two and one half 
whorls, Height of shell, 15.0; of last whorl, 14.0; of aperture, 11.5 ; max. diam.
