Reeve, in accordance with his invariable rule, did not mention 

 any dimensions, but Pfeiffer gave the following measurements 

 (Mon. Helic. Viv. iii, p. 496) from Bensonian specimens: 

 "Long. 9, diam. 4 mill., ap. 3| mill, longa, vix 2 lata." The 

 British Museum possesses specimens from the Kliasi Hills, one 

 of which is composed of 7j whorls and measures 15-5 x7'5 mm., 

 while another, consisting of 8 whorls, only attains a length of 

 14 mm., with a diameter of 6 mm.
