Miiller, who has given an admirable description of this 
shell, informs us that it is a native of Italy. The band 
occupies the middle of the body volution, but is placed near 
the suture of the other whirls. 
UPPER FIGURES. 
BULIMULUS TRIFASCIATUS. 
B. albus ; anfractibus septem bifasciatis, basilar tri- 
fasciato; fasciis rubro-fuscis. 
THREE-BANDED BULIMULUS. 
White, with seven two-banded whirls, the first volution 
with three bands; the bands reddish-brown. 
This shell at first sight bears a near resemblance to the 
preceding species ; but avery slight examination must con- 
vince the experienced conchologist that they are very dis- 
tinct : the outer lip is much thinner, the basal whirl longer 
in proportion, and all the volutions are less convex. Added 
to these characters, the number of bands (which are sub- 
ject to variety in breadth, especially the lateral ones) is 
very constant, and the colour invariably the same, except- 
ing in worn specimens. 
Conchclogy, when rendered subservient to geognostic 
investigations, assumes the rank of an useful science, and 
then becomes a subject of the highest importance. Budi- 
mulus trifasciatus, avery common West Indian shell, occurs 
imbedded in the same limestone which incloses the fossil 
human skeleton, lately sent to the British Museum, from 
the grande terre of Guadaloupe, by Sir A. Cochrane, prov- 
ing that rock to be of modern date, and contemporaneous 
with the existing creation of animals*,

volume of their Transactions.
