 Hab. sub lapidibus ad oras Americas Meridionalis. (Isle of Muerte.) 

 This species has long been known, and has commonly been call- 

 ed Col. Strombiformis. It does not, however, agree with Lamarck's 

 description of that shell, and Mr. Sowerby possesses specimens of 

 another which corresponds exactly with it.

 tricosd, coerulescenti-albidd, fusco punctatd et maculatd ; spird 

 gradatim acuminatd ; anfractibus 8 — 9, longitudinaliter costel- 

 latis ; superioribus decussatis ; medianis subtuberculiferis ; ul- 

 timo medio lecvigato, infra) [spiraliter sulcato ; aperturd oblongd, 

 superne acuminatd, subtus in canalem breviusculam desinente ; 

 labio externo intus denticulato ; columelld arcuatd, Icevi : long. 

 2 T V, lat. Ajoo//. 

 Hab. ad Panamam. 



This species is remarkable for its gigantic size. It must be placed 

 with the Columbellce, although not precisely according with the cha- 

 racter given of that genus by Lamarck j for it is more nearly related to 

 them than to any other genus. A single specimen only was found.
