California (Mus. C timing). 



This locality has not been verified by Californian collectors, 

 and I do not know that the species has been recognized by con- 

 chologists generally : I am unacquainted with it. G. vexillum^ 

 Reeve (fig. 54), appears to be a state of this species in which 

 the flames are replaced by irregular longitudinal strigations ; it 

 is said to come from the Gulf of California, and is equally

Shell elongately turret ed, spire plicately ribbed towards the 

 apex ; whorls flatly convex, fulvous chestnut, encircled above 

 with a white band ; aperture small, denticulated within. 



Habitat unknown- 



This species was described from a single worn specimen in the 

 Cumingian collection. From this specimen, presumably, the two 

 very different illustrations in Sowerby (fig. 57) and Reeve (fig. 

 58) were drawn. Sowerby figures and describes a shell w^ith 

 smooth spire-whorls.
