 Inhabits the East Indies ; and is a land shell. Chemnitz. 

 This shell appears, by Chemnitz's figure, to be about half an 



inch in diameter ; but neither the figure or description is 



sufficiently clear, and I am quite unacquainted with the 



species. 



3LUCANA. 86. Shell urabilicated, nearly globular, 

 with five whirls, and the base gibbous ; outer 

 lip white and reflected.
