 simis cincta ; spira turrito-exserta ; apice valde elato ; labro tenui, 

 acuto, arcuato, juxta spirant emarginato ; apertura fauce fusca. 



Shell oblong turbinated, somewhat fusiform, brown, encircled 

 with a number of very fine thread-like lines ; spire exserted in the 

 form of a turret, apex very elevated ; lip thin, sharp, arched, emar- 

 ginated next the spire, aperture brown with a white blotch: length, 

 1 5-S inch, breadth, 4-S inch. 



Habitat? 



The remarkable feature of this shell is the spirt", which is ex- 

 actly half its length, the whorls very prominent and nine in num- 

 ber. 



I am indebted to Mons. F. Cailliaud of Nantes, for this rare 

 Cone, and have taken tho liberty to dedicate it to him.
