three yellowish white transverse bands ; spire subelevate, 

 acuminate ; whorls 7, flattened, thickly ribbed lengthwise with 

 small obsolete ribs, and very finely girdled with transverse 

 lirse ; aperture narrowed ; columella quadriplicate. 



Kare, Coll. Legrand. The fine ribs are most prominent on 

 the upper whorls. There is a shell very closely allied to 

 this which I have marked as variety a, where the ribs are 

 larger and continuous, and another variety where they are 

 smooth, and the whorls coronate.

M. shell small, fusiformly turretted, pale yellow, zoned 

 with an indistinct white line ; spire acute ; whorls 7, rounded, 

 elegantly thickly ribbed with valid equal smooth shining ribs, 

 which disappear on the last whorl. Aperture rather wide,

Long Bay, rather rare, Eev. H. D. Atkinson. Avery pretty 

 shell, the ribs and somewhat turretted spire give it a scalariform 

 aspect. It is somewhat dull in color.

King's Island, rare. A very small shell, varying somewhat 

 in the shades of its coloring, and not unlike M. tasmanica, 

 above described, except that its ribs are more permanent and 

 larger in proportion to its size.

M. shell small, oblong ovate, somewhat thin, shiny, sub-

Kare, King's Island. A shining banded shell of the series 

 of our M. pica, but much smaller. The coloring seems very
