158 ZIERLIANA. 



Quoy described as M. nigra (= M. Quoyi, Desh., p. 122), may 

 possibly be intended for this variety. 



M. ^ETHIOPS, Reeve. PL 46, fig. 351. 



Dark brown or olive-black, finely decussated. Length, 1 inch. 



Solomon's Islands, Philippines. 



Very much narrower than any of the forms of M. Ziervoge- 

 liana ; yet it may be only a variety of that species. M. creni- 

 plicata, A. Ad. (unfigured) is said by Mr. Sowerby to be a 

 synonym. 



M. ANTHRACINA, Reeve. PI. 46, fig. 352. 



Shell covered by a smooth, black epidermis. Length, 1 inch. 



Me of Ticao, Philippines, on reefs at low water. Cuming. 

 Differs from M. jEthiops only in the want of sculpture.
