BUCCINUM. WHELK. 
slightly toothed within; inner-lip slightly reflected with 
generally two faint distant folds : color whitish, or pale 
ochre: length about half an inch; breadth hardly three- 
eighths. 
It differs from the last, and from the young of B. rcticu- 
latum, in being broader in proportion to its length, in the 
volutions being a little flattened at their tops, and in the 
ribs being more distant and a little swelling at the junctures: 
it wants also the colored spot at the back of the canal. 
Maton and Rackett, and consequently Mr. Dillwyn, in re¬ 
ferring to the fig. 19. in the Dorset Catalogue, not consider¬ 
ing that there are two numbers of this denomination, have 
directed us to that without the star, which is Helix succinea. 
The former authors, in their corrigenda, have strangely 
desired us to erase 19, and substitute 23, a number not to 
be found. 
About Weymouth and Poole, and at Portmamock in 
Dublin bay : rare. v. ?n. 
9. Buccinum tuberculatum. Tubercled Whelk. 
Shell taper, white but not glossy: spires six, rounded 
and well defined by the line of junction, with numerous 
strong longitudinal rib3 crossed by fine transverse lines, 
giving them a tubercled appearance: aperture oval; the 
outer-lip thin and toothed within; inner-lip strongly marked 
with oblique striae, and ending in a short reflected rather 
cloven canal; length six-tenths of an inch ; breadth not a 
third of its length. 
It differs from B. reticulatum in its elongated and taper 
shape, and in the inner-lip and canal; from B. ambiguum, 
in having the ribs more numerous and closer together, arid 
in wanting the stronger tubercles at the junctions of the 
volutions ; from B. hepaticum, in not having the volution* 
entirely covered with tubercles; and from all, in the strong 
oblique striae on the pillar. 
Found in the sand at Exmouth, and is in the cabinet of 
Mrs. C. W. Loscombe: very rare, v . m .
