 chestnut band, comi)osed of macnlations ; aperture violaceous

This species, descrilu'd t weuty-five years ago. but never figured, 

 remains unrecognized. Carpenter, who so thoroughly studied 

 the mollusca of Mazatlan, and of the West Coast of North 

 America, could make nothing of it. Philippi compares it with 

 G. azora, Dnclos, which, he says, it resembles in form but differs 

 in being one- instead of three-banded.
