These 2 specimens were found beached on the Atlantic coast of Portugal. My guesses are:
1) Mitra cornicula? (ca. 30mm) http://www.gastropods.com/6/Shell_2246.html
2) Euspira guillemini? (ca 15mm) http://www.idscaro.net/sci/04_med/class/fam3/species/natica_guill1.htm

Can someone confirm these 2 guesses? Or are they wrong?

Many thanks, Mike
