158 ZIERLIANA. 



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

 possibly be intended for this variety. 



M. ^ETHIOPS, Reeve. PI. 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-

 synonym. 



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

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