BUCCINUM, Linn. &c. 
Gen. Char. Univalve; spiral; oval , or elongated ; 
aperture nearly longitudinal,, oblong., with a 
reflected sinus at the base of the columella,- 
Columella plain,, tumid. 
BUCCINUM elongatmxu 
TAB. CX.—Fig. 1. 
Spec. Char. Shell ovate-elongated, transversely 
striated; whorls seven, rather convex, longi- 
tudinally undulated ; outer lip obscurely ere- 
nulated within; mouth oval with a short re- 
curved sinus. 
A wice as long as wide, the aperture is rather less than 
half the length ; the undulations upon the lesser whorls are 
tolerably regular and straight ; upon the last whorl they 
are less uniform and more curved ; the inner lip is smooth 5 
thicker at the base. 
Some doubts may be entertained, of this being a trifling 
variety ofB. undatum of Linn, with greater regularity in 
the undulations, since we know how much the B. undatum 
varies in that respect : indeed it is with much uncertainty 
I give it here as another species. The length of the spire 
may perhaps distinguish it, wherefore I have called it 
elongatum. Mr. Herbert brought this shell from Walton le 
Soken Crag-pits, Essex, in 1810. I do not at present know of 
another specimen, but would recommend further search to 
be made after fossils so nearly related to recent shells. It is
