Hah. Karpatho island {Spratt). 



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.

 Hab. Island of Crete, without exact indication of habitat {Spratt). 

 This little species is very closely allied to 0. 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 iu the profile view obliquely in a nearly straight line, 

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

 horizontally into the midst of the mouth.

Habitu C. byzantinse, Ohrp., typicce, sed apparatu elaustrali 

 C troglodytis. Ad. Schm. — Differt a typo punctis cinereis 

 parce adspersa, anfr. mediis glabratis, vix substriatis, apert. 

 minus protracta. Alt. 21, lat. 4 mm.; alt. apert, 4|, lat. 

 apert. 3| mm. 

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

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

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

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

 very slight or nearly obsolete striature.
