TURBO sculptus. 
TAB. CCCXCY .—fig. 2. 
Spec. Char. Conical, with minute longitude 
nal fetriee and deep transverse sulci ; whorls 
rounded, separated above by a canal ; um- 
bilicus small ; aperture sulcated within. 
Syn. Turbo sulcatus, Pilkington, Linn . Trans .

Very similar in form to Cyclostoma elegans : the aper- 
ture is obovate rather than round, thus it is not strictly 
a Turbo ; it has not the reflected margin of a Cyclostoma, 
hut has a small slightly recurved expansion near the um- 
bilicus, similar to that part of the lip in Scalaria. The 
upper part of the aperture has an angle corresponding 
with the upper edges of the whorls ; the length is greater 
than the width. 
Not rare at Barton; I have received good specimens 
from several kind Friends. It has been necessary to 
change the specific name given by Mr. Pilkington, for 
it has already been twice used in the same Genus by 
Gmelin, &c. 
The two shells before us do not, it must be owned, 
agree precisely with the characters of the Genus Turbo, 
as they are given by Lamarck, but the discrepancy is 
not sufficiently great to warrant the placing them in any 
other, they form a passage towards Delphinula, from 
which however the sculptus is quite distinct, and they 
are so nearly allied to each other, that it would be doing 
a violence to nature to separate them.
