A more attenuate shell than B. chemnitziana, usually re- 

 taining more whorls. It is widely distributed over the plateau 

 of the centre and the western half of the island, but does not

 of B. chemnitziana. The specimens sent by Mr. Jarvis from 

 Aenon Town are small, 19 x 3.3 to 22 x 3.8 mm., with 7y 2 to 

 whorls below the plug.
