A handsome dark purple-brown shell, much shorter than E. 

 aurantiaca. The narrow sutural border is defined by an im- 

 pressed line, and at the suture itself a. very narrow whitish 

 line runs. Under a strong lens very weak traces of spiral 

 lines are visible. The columella is more concave in a front 

 than in an oblique view, and the outer lip is strongly arcuate. 

 One of the type lot measures, length 20.5, diam. 10, aperture 

 9.5 mm.

Shell subfusiform-oblong, pellucid-corneous or whitish;

 Whorls 5, rounded, polished, longitudinally strongly striate, 

 under a lens transversely striate. Columella twisted, ab- 

 ruptly truncate, whitish; aperture moderate, the lip white- 

 edged. Length 19.5, diam. 9, aperture 9x4.5 mm. (Da C.).

This species bears a strong resemblance to G. underwoodi 

 Fulton, but differs from it in having a more attenuated spire. 

 The color is generally much paler, in fact occasionally it is 

 nearly white, while the columella and peristome are always 

 white (Da C.).
