I have been enabled to examine nine specimens of this distinctly 

 marked species, all of which, however, were females. In general 

 appearance these have a superficial resemblance to the genus Melam- 

 psalta. 



[Since writing the above I have discovered one male specimen of 

 this species in the Godeffroy collection, which was received from 

 Sydney. The opercula are pale ochraceous, with somewhat paler 

 margin, and about reach the base of the first abdominal segment, 

 they are slightly directed inwardly, the inner margins rounded and 

 produced, but considerably apart, and the posterior margins wide and 

 very slightly rounded.]
