Hab. E. Mexico: Orizaba (Botteri'). 
The author knows only one specimen, and that bleached, but he states that it 
differs from all those described and figured in the work of Fischer and Crosse by the 
close costulation (170 costule on the last whorl), without visible interstices. He 
compares the species with £. boucardi, but the aperture is not so remarkably drawn 
out and bent backwards.
