dian Archipelago may with more propriety claim this interesting and ge- 

 nerally valued shell as a native of their coasts. It is the Weaver's Shut-

 Hab. ad littora Insularum Indiae Occidentalis. Mus. Goodall, nost., &c. 



Desc. Shell oblong, narrow, dull violaceous; columella and outer 

 lip straight; upper canal forming an obtuse keel on the outside; outer 

 lip scarcely thickened, slightly angular near the base, columella with a 

 slight longitudinal groove near and rather below the middle. 



We have several varieties of this species, both in colour and form : the 

 first is white, with a violet line along the middle of the columella; 

 another is of a sulphur colour with a similar violet line; a third is rather 

 more ventricose and of a violet colour, and the fourth of a greenish 

 yellow, and of the same form. It is a native of the West Indies.
