N.B. reporting of the edit history is currently fairly unclear and misleading. Most edits made to specimens appear as a pair of 'add' and 'delete' entries, which may not be together in the list. There are also often 'minor' edits, which are made automatically (rather than due to user activity), for example to merge synonym names.

I have modified the sheet as it appears to be a mixed gathering - see the two IDs of Dandy. I have had to assume that Ley collected both spp on the same occasion.
