 The elegant Zizyphinus. Shell shaq)ly conical, de- 

 pressly tumidly rounded towards the base, yellowish, 

 whorls concavely sloping, granosely ridged, ridges 

 distant, grains also rather distant, interstices broadly 

 excavated, especially at the sutures, ridges violet- 

 brown.

 Cuming. 

 The grains, which on the upper part of the whorls are 

 rather distant from each other, gi-adually diminish in size, 

 and approximate towards the base, where they amalga- 

 mate into smooth cords.

 The necklace Zizyphinus. Shell erectly conical, rather 



swollen at the base, transparent white, encircled by 



a necklace of violet spots, whorls concavely sloping, 



spirally ridged, ridges smooth, the two basal ridges 



more prominent. 

 llab. Port Curtis, East Australia. 



The necklace of violet spots has an exceedingly pretty 

 appearance on the delicate transparent ground of the shell.
