Shell dextral, conical, solid, pointed at the apex ; last whorl ven- 

 tricose ; striae decussating ; whorls 6, rounded ; suture moderate ; 

 aperture subovate ; columella short, terminating in a very strong 

 plait ; lip white, broadly expanded and subreflected ; umbilicus open ; 

 colour dark chestnut sprinkled with white, with a white band sub- 

 central on the last whorl. 



This shell approaches in form the genus Partula. Having ob- 

 tained the specimens alive, I have been enabled to examine the ani- 

 mal, and can find no marks to distinguish it from the common type 

 of the genus Achatinella.
