 — I think it just possible that my specimens may belong to 

 Miiller's species (which iinds representation under some- 

 what diverse figures), and cannot take the responsibility of 

 describing the Madeira species as new on the strength of 

 merely two specimens, obviously of one species, but of 

 which oue is little more than embryonic and the other is 

 slightly chipped. At the same time I greatly doubt whether 

 they can be left under this name : their spire is too high, 

 the corner of the outer lip droops too far below the plane 

 of the apex, and the sculpture is too fine, too uniform, and 

 too sparse to suit Miiller's species.
