TURBO scLilptus. 

 TAB. CCCXCV.— j^-. % 



Spec. Char. Conical, with minute longitudi- 

 nal fetriae and deep transverse sulci ; whorls 

 rounded, separated above by a canal ; um- 

 bilicus small ; aperture sulcated within. 



Syn. Turbo sulcatus, Pilkington, Linn. Trans. 

 VII. 'p. 118. tab. 11. Jig. 9. 



V ERY similar in form to Cyclostoma elegaus : the aper- 

 ture is obovate rather than round, thus it is not strictly 

 a Turbo ; it has not the reflected margin of a Cyclostoma, 

 but 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 ; T 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 

 Gmclin, &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.
