Recurring at a different part of its surface, from that of the 
'? r «ier. The spire also is more obscure, of less propor- 
ofiate diameter, and with fewer revolutions. The canal is 
. lQr ter and less deflected : the replication covering a greater 
j ° rt ion of the columella. It is subject to similar variety in 
tubercles of the outer lip ; but they are fully formed 
■ I f >n advanced age. The colour is usually much brighter 
s u,ri that of P. L ; but it is sometimes banded, as in that 
J'ecies. Although from injury received in growth, spe- 
a " ne »s of P. Lapillus may be sometimes found, which 
gPpfoach somewhat nearly to the other, yet in well formed 
jj !e, 'ituens the ilifferences are so great as to leave little room 
?' doubt of their being distinct. I have seen three spe- 
. '"ens of this animal, with the extremity of their shells 
d ( Sf | r fed under that of a common Limpet, and feeding on its 
BUCCINUM. 
;j 'NEFiIC CHARACTER: The shell oval or ovate, 
nonieal. Aperture longitudinal, with a notch at the base; 
ont no canal. Columella not flattened, turgid at the upper 
Part. 
Lamarck had separated into a distinct genus, under the 
1,., of Nassa, those which have a callous columella; but 
16 li - 
as since reunited them to the Buccina.

pd often taken up attached to fishermen’s lines. It is 
rc quently devoured by the Scate, the animal with the 
Porculum attached being found in its stomach; but it 
i Ce '»s that the shell is speedily rejected, and in this state 
affords an habitation for the Hermit Crab: the largest 
specimens of which are commonly found in these shells. 
c urious net work of membranous capsules, sometimes 
birge as the clenched fist, found on the shore after 
°rtuy weather, is the case in which the spawn of this 
ln 'al is produced. In their original state, they are 
0 j. cbed to stones or shells; and when washed on shore, 
le n contain the young shell, which differs much from the 
* ft 1 shape.
