g GENUS BUCCINUM. 



Length 2 inches. Width 9 lines. 

 Inhabits the seas of England and Norway. 



This species is easily distinguished by its turreted form, the 

 ridges and transverse stria?, and by the slightly angular whirls of 

 the spire.

B. testa ovato-oblonga, rugis convexiusculis succincta, griseo-rufescente, 

 anfractibus convexis, margine superiore planis et adnato limbosis ; aperturk

Shell ovate-oblong, reddish, surrounded by strongly promi- 

 nent ridges, which are seven in number upon the lowest whirl. 

 Between the ridges are seen pretty fine and very regular 

 striae ; longitudinal lines, slightly apparent and distant, of a 

 deeper color, form upon t^ie ridges species of rings. Epider- 

 mis of a deep brown color ; spire composed of six distinct, 

 convex whirls, the lowest very large, compressed and re-enter- 

 ing at its upper part ; aperture ovate, elongated, whitish, pretty 

 strongly emarginated at its base ; lip slightly undulated, form- 

 ing at its upper and internal part, a small canal. The colu- 

 mella is white and slightly arched. 



Length 2 inches 3 lines. Width 14 lines. 

 Inhabits the coasts of the Cape of Good Hope. 



We restore to the genus BUCCINUM this species, which La- 

 marck placed among the Purpurae, under the name of PUR- 

 PURA ligatum; it is very analogous to the BUCCINUM Anglica- 

 num ; but it nevertheless differs, in that the whirls of the 

 spire are less turreted and less convex. The aperture is much 

 larger and more effuse than in that ; lastly, the brown lines 

 do not exist upon the BUCCINUM Anglicanum, and the ridges
