 Hah.— Vovtsea, Port Phillip. 



Observation. — Size of type: Length, 9; latitude, 5; altitude, 2' 

 mm. Tate and May place this as a synonym of M. niyrita, 

 Sowerby, a species that it strongly resembles, but it may be dis- 

 tinguished therefrom by its much finer sculpture, the undulating 

 outline of the outer edge, and it is usually marked by "two red 

 lines on the back forming a cross." We therefore consider it 

 worthy of rank as a species. 



M. nigrita, was well known to Mi-. Beddonie. We have an ex- 

 tensive series from other States, and have no difTiculty in separating 

 it from M. crucis.
