Dear colleagues,

there is a Fissidentalium rectum (Gmelin 1791) mentioned in some books to be
occuring in the deep waters  of the mediterranean, but it is not clear
whether it is a recent species or if the location is right. The only picture
I ever saw was in P. Dance "The collectors encyclopedia of shells" 1990,
p.27 with the note "mediterranean, uncommon".
Today I saw in magazine of the Zoological State Collection in Munich another
Fissidentalium shell of about 70 mm length labelled D. rectum Gmelin,
mediterranean, from a collector of the early 1900s. It looks like the shell
in Dance and it was not fossil.
Do anybody have some information on that species (except the short notice in
Pilsbry&Sharp 1897) and on its habitats and distribution?  Any confirmed
findings in the mediterranean?

Best regards from Munich
Bernd Sahlmann
