anfractibus 8 — 9, ultimo antice transversim sulcato ; apertura 

 longitudinal!, sub-flexuosa; labii externi crassi margine 

 antico tenuiusculo ; labio interno lamellam levatam colum- 

 ellarem instructo ; canali brevi, sub-reflexo. 



Shell oblong, smooth, white, with unequal angular rusty 

 spots, apex acuminated ; spire rather elongated, volutions 

 8 — 9, the last transversely sulcated in front; aperture longi- 

 tudinal, sub-flexuous ; anterior edge of the thickened outer 

 lip rather thin ; edge of the columellar lip slightly raised 

 anteriorly ; canal short, somewhat reflected. 



Very nearly related to Col. flavida. It appears to be 

 very rare as we have only seen two specimens in Mr. 

 Cuming's collection. Lamarck says it is found in the Medi- 

 teranean. We suspect it belongs to the South Seas.
