8 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 strie, 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 ; apertura 
‘alba, levigata. 
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 
strie ; longitudinal lines, slightly apparent and distant, of a 
deeper color, form upon the ridges species of rmgs. 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 Purpure, under the name of Pur- 
PuRA ligatum; it is very analogous to the Buccinum Anglica- 
num; but it nevertheless differs, m 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
