Enigmatic Variations 1661 By Chalicea

[Matakari]

Good day, Chalicea, one of my favourite setters, brings a pretty tricky offering for the EV this week. Help with the following would be appreciated, thanks in advance!

25a Fortification of constructed mansion-house sons abandoned ( 7 ): ?O?????

31a Non-Muslim; initially discovering him, I’m upset ( 6 ) : D?????

2d Firearm’s weight is carried by member ( French one ) ( 8, 2 words ) : ?RW?S???

4d Large African animals mounted indeed in exhibition hall ( 6 ) : ?W????

18d Backing dip into set of people in sort of implantation ( 8 ) : ??GA??M?

22d Something that expands retrospective cover on American tour ( 7 ) : ?AG??I?

 

PREAMBLE: Four statements made by 13 Across circle the grid in a clockwise direction, beginning at cell 13. A final S is ignored in one of them. Extra letters produced by the wordplay in 27 clues, read in clue order, give another of his statements. The PIG LATIN is not in Chambers Dictionary ( 2016 ), which is recommended.

25 Take 'sons' out or 'mansionhouse' and anagram it.

31 - 'Initially discovering ' gives the first letter, then a three-letter word from the clue, followed by 'I'm upset', ie reversed.

You have mistakes in 2, 4, 18 and 22.

Thanks, Scorpiojo, Toorak, NACW! 25a carries 7 letters and does accommodate Mahoenui. Answers for 4, 18, 22? Thanks!

25 Moineau (thought you'd spot that). I'm sure you've remembered the 'extra letters in wordplay'. Here it's the H.

4 Nyalas

18 Nidation

22 Dilator

Hope this is enough to get you on the right track - the last Chalicea turned into rather a nightmare for you!

25a The H is a surplus letter so anagram the other 7
