VA GENUS BUCCINUM. 
This large and fine species was much sought for several years 
since; it is less rare at present in cabinets; it is found even 
24 inches in Jength. M. Edoux, a distinguished naturalist, 
collected in his voyages a large number, which he has lately 
brought home. 
25. BUCCINUM ACHATINUM, Lam. The Agate Buccinum. 
(Collect. Mass. Lam.) Lisv., pl. 977, fig. 18. 
Pl. VII, fig. 21. 
B. testa ovato-elongata, turrita, levi, luteo-rufescente ; anfractibus con- 
vexiusculis, superné confluentibus; spird apice obtusiusculd; apertura 
levi, basi latiuscula. 
Shell ovate, elongated, subturreted, smooth, polished, of a 
reddish yellow color, composed of seven whirls, hardly con- 
vex. The suture which separates them is simple, shallow, 
submargined ; the summit moderately pointed. Pretty promi- 
nent strie of growth are seen upon the lowest whirl ; aperture 
ovate, smooth, widened at the middle and strongly emarginat- 
ed at its base ; columella yellowish, smooth and arched; a 
keel, continued from the upper third of the aperture to the 
base of the right lip; the space between the keel and the 
edge of the lip is filled with oblique folds. The right lip is 
simple, thin, sharp, and slightly effuse towards the middle. 
Length 2 inches. Width 6 lines. 
Inhabits the Bay of the Cape of Good Hope. 
This species, though common, is rarely found perfect in 
collections. The specimens which we procure are almost al- 
ways partially worn, by the violence of the waves by which they 
have been cast upon the shore. It appears to be found only in 
very deep water. The animal resembles that of the smooth 
Buccinum, and like it is blind.
