BUCCINUM labiatum. 
TAB. CCCCX11 —Jigs. 1 and ± 
Spec. Char. Ovate acuminated, costated, 
transversely striated ; striae numerous, large, 
elevated and rounded; whorls convex ; 
aperture oblong ; its outer lip enlarged in 
the middle, and striated within. 
T he striae upon the surface of this shell are almost pro- 
minent enough to be called carinae ; they are nearly close 
together, and alternately large and small ; the lip is thin 
and sharp, it has a very obtuse sinus that occupies its 
upper half, the lower half being enlarged ; the beak is 
rather wide, open and twisted ; the costae are numerous, 
long, and curved ; the upper parts of the whorls are 
slightly concave. 
Found at Plumstead by the Rev. H. Steinhauer in 
1812, ; the Rev. Mr. Iremonger met with it on the 
Hampshire coast, and it has since been found in Colwell 
Bay on the Isle of Wight by Professor Sedgwick ; it ap- 
pears to abound wherever it occurs, and is probably 
characteristic of the so-called upper marine beds. 
Fig . 1, is from a Hampshire specimen, and Fig. 2, one 
from the Isle of Wight. 
BUCCINUM lavatum. 
TAB. CCCCXIL —Jigs. 3 and 4. 
Spec. Char. Ovate acuminated, costated, fur- 
nished with many acute carinae, and trans- 
versely striated ; aperture oblong ; lip ere- 
nulated at the edge, and striated within; 
whorls convex. 
Syn. Buccinum lavatum, Brander, f. 10. 
All the carinae are sharp and equal ; they are enlarged 
as they pass over the curved costae ; the strise between 
them are minute, but very regular : these characters will 
distinguish this shell from the one just described, when 
the aperture is imperfect; when that is perfect, its 
notched edge without a sinus adds to the certainty. 
Extremely abundant in the blue Clay of the Barton 
Cliff.
