cupied by Sowerby, Reeve changed it as above, and Pease subse-

umella three-plaited. Length, 7 mill.

I have not seen a specimen of this shell, but the figure is so 

 close to M. Paumotensis, Pease, that I suspect it will prove to 

 be synonymous with that species.

 nut ; columella four-plaited. Length, 5 mill.
