Lacuna macmurdensis, sp. nov. (Plate L, Fig. G) 



Shell small, turbinate, thin, and loosely coiled. Colour, pale buff. Sculpture : 

 three strong peripheral keels, beneath which are two smaller threads. Base

This appears to represent L. noto-rcadcitsis, Melvill and Standen,* from the opposite 

 coast of Antarctica. It differs by having the shoulder of the whorl sloping instead 

 of flat, fewer and more prominent keels, and a broad smooth area between the lowest 

 keel and the umbilical margin.
