Hab. Ranai. 
Shell dextral, conical, solid, pointed at the apex; last whorl ven- 
tricose ; strize 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 subcentral 
band on the last whorl. 
This shell in form approaches 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.
