Dear Paul, Ross and other shellies, first of all I have to say hallo to each all for introducing myself to the list. I am a Ph.D. student at the University of Bielefeld / Germany and more of a leisure time conchologist since my main research field are Terrestrial Isopoda, although I do some research on fresh water bivalves. And now I'd like to make a short comment on Paul Monfils' exhaustive course in nomenclature: As far as I know suffices for geographic expressions ending on -ensis are exclusively for female and male names, the neuter form correctly must be -ense, e.g. Cerastoderma (neuter though ending on -a) hauniense or in a wider context -is is changing to -e e.g. Mytilus edulis vs. Cerastoderma edule or Dentalium vulgare. Made I mistake on it? A nice day to all of you, Andreas --------------------------------------------------------------------- Andreas Leistikow Universit t Bielefeld Fakult t f r Biologie Abteilung f r Morphologie und Systematik der Tiere Morgenbreede 45 D-33615 BIELEFELD / Germany e-mail: [log in to unmask]
