MINI CRYPTIC CROSSWORD PLUS

(click here for a PDF version)

In this cryptic crossword, the answer from the wordplay half of each clue contains an extra letter. For example, if the clue were "Shy memo for North American canine (6)", the answer would be COYOTE, as clued by "North American canine"; the wordplay half clues COY+NOTE, which has an extra N. These extra letters can be anagrammed to produce this puzzle’s final 8-letter answer.
