• Copy the label and relevant determination slip for the specimen (or specimens) that are being removed and alter the collector’s number from “999” to “999 p.p.” for both collections (p.p. = pro parte or in part).

• Separate the specimens into two parts representing each taxon. If the specimens are taped the tape can usually be cut and the specimen(s) removed, leaving the mounting sheet intact. If the specimens are glued, or the specimens are many and small, cut the sheet up and glue the portions to new mounting sheets. Provide a new CANB number to the relevant sheet.
