BUCC1NUM tetragonum. 
TAB. CCCCXIY.-; fig. 1 . 
Spec. Char. Squarcish, ovate, pointed, cos* 
tated ; costae crossed by four large and 
several small ridges ; aperture oblong ; lip 
toothed within. 
A thtck rather square rugged looking shell ; the large 
ridges divide the surface between the costae into cells, 
that are crossed by the smaller intermediate ridges : it 
is probably when perfect, covered with concave scales ; 
their remains give it much the aspect of a Murex : the 
beak is short, and but slightly curved ; the teeth in the 
iip are about seven, they are blunt. 
But one specimen of this species is in Mr. Sowerby’s 
cabinet; it was kindly placed there by Mrs. Cobboldj, 
who found it near Ipswich. 
BUCCINUM incrassatum; 
TAB. CCCCXIV- fig, 2. 
Spec. Char. Thick; ovate, pointed, rugged, 
with about five carinae, the uppermost 
largest; aperture oval; lip obscurely fm> 
rowed within. 
The few nearly smooth, large, principal earinae, with 
very slight indications of lesser ones between them, and 
the weight of this shell will always make it easily knowm ; 
the obscure furrows in the lip form obtuse teeth be* 
tween them, and are opposite the earinae ; the deep and 
distant lines of growth make the surface rugged. 
An abundance of this very distinct species in all 
stages of growth, has been found by the Rev. G. R, 
Leathes in Suffolk, and a liberal supply sent for figure 
jug.
