Conversion of Ficus for a clade of snails would= =20 prevent subsequent conversion of Ficus for a clade of plants. If= =20 this were to occur, a new name Phytoficus might be selected for the= =20 plant clade. Alternatively, because Ficus is a very well known name,= =20 one could propose that the CPN conserve Ficus for the plant clade,= =20 and the snail clade would have to be renamed. Phil --=20 Philip D.
