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.

Nassarius (Nassariidae)
Nassaria (Buccinidae)
