Hub. Philippine Islands ; Cuuiing. 



Though apparently smooth, this species, like M. scripla, 

 which it very closely resembles, will be found, on exami- 

 nation with the lens, to be minntelv deeussatelv striated.

The riTTED Meuoe. Shell triangularly ovate, rather 

 narrow, nearly eijuilateral, whitish, profusely retieu- 

 lately blotched with livid-purple, very closely concen-

Ilab. Philippine Islands ; C'uming. 



Conspicuously distinguished from M. picla, which it 

 resembles in painting, by its nan"ower and more equilateral 

 form, deeply-cut ribs, and correspondingly deeply-cut liga- 

 mentary area.

Hub. Indian Ocean. 



In this species, which is the original type of the group, 

 the anterior side is much produced, whilst the posterior is 

 more than usually slopingly truncated. The painting is 

 exceedingly variable.
