The Marquis of Monterosato (Enumerazione, p. 45) says that the living Mediterranean species 

 Pleurotoma loprcstiana, Calc., has been confounded with the Pleurotoma crispata, Jan. If I have 

 not followed him here it is merely because I do not know the limits of the two species, and therefore 

 think it safer to follow the nomenclature of the British Museum, which has specimens under the 

 name of Jan's species, and it is with these that the Challenger shells agree.
