Shell cylindraceous-fusiform, usually slender, strong, 

 nearly opaque, with a satin-like lustre, chocolate brown, 

 with, for the most part, short irregular whitish, or ash- 

 coloured streaks or spots ; whorls, from seven to eleven 

 (usually ten), in number, flattish, or only moderately 



outer lip is flat, thick, milk-white, and very broad. From this last character it 

 has been conjectured that it was identical with the Turbo labiatus of Montagu, but 

 the figures given by the two writers are dissimilar ; perhaps, however. Da Costa's 

 (Brit. Conch, pi. 5, f. 1 5, copied as pi. 21, f. 15, in the Dorset Catalogue), although 

 from its rudeness it is impossible to pronounce with certainty upon it, was drawn 

 from our nigricans, and enlarged to the size of the supposed adult.
