List of lapses (6)
I believe the answer is:
errata
'list of lapses' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for errata that I've seen before include "Noted mistakes" , "List of mistakes (in book)" , "List of errors" , "Mistakes in printing or writing" , "Mistakes in printed material" .)
