This species seems to be nearly allied to G. conferta, but distinguished by an evident 
difference in the sculpture of the last whorl, the upper half being costulated, the lower 
half smooth. The costulation renders the suture crenulate. There are some impressed 
varices, white and pale brown. All the quoted descriptions agree in these characters; 
but the figures given by Pfeiffer himself1?, Fischer and Crosse 4, and Strebel ° differ 
so much in shape znter se that I am at a loss how to reconcile them as belonging to 
one species—Pfeiffer’s figure is somewhat biconical, like G. conferta, Fischer and 
Crosse’s more narrowly cylindrical (perhaps not quite full-grown ?), and Strebel’s fig. 46, 
on the contrary, more ventricose, widened below. But as all these authors refer their — 
figures to the same species and I have no specimens for examination, I dare not make 
any change of names.

Quite peculiar in this genus by the regularly tapering spire and the rather broad 
pale band in the upper half of the last whorl.

Pfeiffer speaks’ of opaque yellowish irregular spots and streaks in this species. A
