Antiplanes

Antiplanes is a genus of sea snails, marine gastropod mollusks in the family Pseudomelatomidae,.

Description
(Original description) These deep-water and abyssal forms are smooth except for incremental lines and sometimes fine spiral striae. The periostracum is conspicuous and the shell disposed to be chalky. The anal sulcus is shallow and more or less rounded, usually situated some distance from the suture, but not quite on the periphery of the whorl. The siphonal canal is rather wide and long and often a little recurved. The aperture is unarmed. There are both dextral and sinistral species.
