P. micaiis Hartm. 



Obs. — This shell was collected by Mr. John Brazier and pre- 

 sented to Mr. Pease. Heretofore I confounded this shell with 

 Coxi Angas MS., and micans Pfr., it is smaller than either of 

 the former and very thin and pellucid. It is the smallest Partula 

 known.

Obs. — Through the kindness of Captain Brazier, of Sydney, 

 Australia, I have been presented with a number of examples 

 from the original lot collected by himself. It is rather larger 

 than pellucida Pse., more elongated ; the aperture is also larger 

 and more elongate, and the lip more expanded. The length of 

 pellucida is 10 mill., while that of Coxi is 15 mill.
