"This is a pale straw-colored glassy shell with rather long 

 whorls, which are minutely (not very distinctly) puckered 

 above at the suture. This feature is not mentioned by Mr. 

 Taylor in the original description (Quart. Journ. Conch, vol. 

 1. p. 282), nor is it depicted in the figure (pi. 1. fig. 5), in 

 which the aperture is drawn rather too narrow. " (E. A. 

 Smith) .

Very slenderly turrited, closely, weakly striate, glossy, 

 translucent, pale yellow, with rather blunt apex. "Whorls 8, 

 the first globular, the second and third 'convex, comparatively

 larly increasing in diameter, only weakly convex, with mod- 

 erately deep suture. Aperture somewhat oblique, three- tenths 

 the shell's length, between piriform and ovate. Outer margin 

 thin, almost straight, basal margin rounded, columellar mar- 

 gin a little arcuate, somewhat thickened, weakly and obliquely 

 truncate below. Length 12, diam. 2.5, aperture 3.5 x 2 mm.

It stands between S. pergracilis and intermedia, but while 

 the upper whorls are more equal, the lower increase more 

 rapidly in diameter than in these two species. In this re- 

 spect, and the bright gloss, it approaches S. paucispira some- 

 what (Marts.).
