540 THE VOYAGE OF H.M.S. CHALLENGER. 



Habitat.— Mediterranean, Madeira (Watson); Atlantic coast of France (Fischer). 



Fossil. — From the Middle Pliocene onwards (Seguenza). 



The identification of this shell with the Madeiran species I am quite sure of, and the Marquis of 

 Monterosato some years ago identified that Madeiran species for me with the species of Philippi. At 

 the same time I confess the latter identification is one I would not have made, so far as I know the 

 form which bears Philippi's name ; but the Tenerife specimens are in too bad condition for much 

 independent examination, and the inquiry as to the Madeiran species I cannot pursue further 

 just now.

To repeat here once more what has been so often urged by others, that the name of Da Costa 

 has priority by fourteen years over that of Olivi, is irksome but still unfortunately necessary, so 

 resolute are some foreign authors in clinging to their mistake on this subject.
