 Mediterranean, Mogador, and Senegal ; but it has not been recorded from 

 the Canaries. I never found it nor have seen it from Madeira, and the 

 shells labelled as this species in Lovre's collection belong to C. sulcosa. 

 Having it therefore as Madeiran on Senr. Nobre's authority alone, with no 

 information beyond the name, and in absence from his list of the common 

 C. sulcosa, I may, I trust, without discourtesy, hold the species as more 

 than doubtfully Madeiran.
