pale' fawn-colour; columella with only one oblique fold, 

 above which upon very close examination the faintest possible 

 indication of a projection may be perceived.

 a Voluta uniplicata, which it has been suggested should be 

 called a Guivillea ; but I find that the single fold is not even 

 a specitic cliaracter.
