Dear Bjorn Here's my version: ?Agenus aspecies -genus assignment doubtful Agenus ?aspecies -species assignment doubtful ?Agenus ?aspecies -both genus and species assignment doubtful. I do it this way for two reasons: 1- placement of question marks is consistent with placement of cf and aff designations; 2- there is no possibility that the containing sentence could be misconstrued as a question.

Paleonet@nhm.ac.uk ac.uk cc Subject 01/09/2006 07:54 PM paleonet question marks in taxonomic names Please respond to paleonet@nhm.ac.uk Dear colleagues, when the status of a taxon, or the taxonomic position of a specimen is not clear in some taxonomic papers the taxa contain question marks at different positions, such as: ?Michelinoceras michelini (Barrande, 1866) Michelinoceras? michelini (Barrande, 1866) Michelinoceras ?michelini (Barrande, 1866) Michelinoceras michelini? (Barrande, 1866) I guess, every position has a different meaning and the position is regulated by a rule of the ICZN. However, where can I find this rule and where is written what the the meaning of each specific position of the question mark is? Any information is appreciated Bjoern ---------------------- Dr. Björn Kröger Museum für Naturkunde an der Humboldt Universität Berlin Invalidenstr. 43 D-10115 Berlin Germany
