This magnificent shell, at present unique, defies comparison 

 with any iiitherto known species. The most prominent

 spire, which is quite symmetrical and has no appearance of

 body-whorl is gracefully attenuated towards the base and 

 slightly rounded at the angle, which is surmounted by a 

 narrow keel. The surface is sculptured by rather numerous 

 shallow spiral grooves and longitudinal minute irregular 

 plicae. Li colour it is rather light fulvous yellow, with white
