Do the rules of taxonomy allow for generic names that are identical except for the gender-specific suffix? For example, since we already have the molluscan genus Cancellaria, would it be allowable to name a new genus of mollusks (or other animals) Cancellarium, or Cancellarius? Seems like this could cause of a lot of confusion. Source of my question: Nassarius (Nassariidae) Nassaria (Buccinidae) Paul M
