A very characteristic little variety.

Admiral Spratt found this smooth little species in the Pass of 

 Prevli and a slight variety at Sitia (?), island of Crete.

 Bab. Island of Crete, without exact indication of habitat (Spratt). 

 This little species is very closely allied to C. virginea, Pfr., but 

 neither so ventricose nor so smooth and polished in the median 

 whorls ; its mouth is strikingly smaller, and the base of the inferior 

 lamella ascends in the profile view obliquely in a nearly straight line, 

 whilst in C. virginea it shows a concave base and projects more 

 horizontally into the midst of the mouth.

 Hub. Roumili near Tarrha, South Crete (Spratt). 

 This variety has quite the form and size and the glabrated median 

 whorls of the typical C. byzantina, Chrp., from Khania ; but it is a 

 true V. troglodytes the costulation of which has been reduced to a 

 very slight or nearly obsolete striature.
