Daphnella bella, Pease (unfigured), and PI. gemmulata, Desh. 

 (PL 22. fig. 51), are synonyms. 



M. GIBBOSA, Reeve. PI. 24, figs. 24, 25. 



Whorls nodulous at the shoulder, smooth, ribs slightly 



flexuous ; ashy white, encircled by faint orange-brown lines, 



back stained with pale black at the upper part. Length, 7 mill. 



Philippines, on the reefs (Cuming) ; Swan River, Australia. 



M. Novse-Hollandide, Reeve (fig. 25), appears to be only a 

 variation of the main characters of this shell.

Shouldered, plicately ribbed, transversely obsoletely striated ; 

 cinnamon-colored, narrowly white-banded. Length, 13 mill. 



New Guinea, Straits of Macassar, and Malacca.

Shell ovate, attenuated at both ends, smooth, transparent, 

 shining, longitudinally closely ribbed, whitish, brown at the 

 base, sometimes with three narrow, interrupted bands. 

 Length, 5 mill. 



Habitat unknown (Reeve) ; Darnley Isl., 



Australia (Brazier) ; Philippines (Ad. and Reeve). 

 M. trivittata, Ad. and Reeve (PL 22, fig. 63), appears to be a 

 banded form of this species.

 light brown. Length, 7 mill.

 from the Philippines.
