on the axis of C. 8aTleana and Hjalmarsoni. It is curious 

 that no species peculiar to Jamaica has a similar character of 

 axis.

 sis et strigis obliquis fusco-corneis variegata; spira ovato-conica, apice

Habitat, Turks Island, also Inagua, Bahamas. 



RemarJcs, This species is allied to M. Hermanni^ Pfr., of 

 Haiti, but is less distinctly costulated, the suture not crenu- 

 lated and has thicker peristome. 



I dedicate the species to the late Mr. Robert Swift, from 

 whom I originally received specimens.
