Beelzebub 1,276 – Fifteensquared

This all seemed fairly straightforward for the most part, with Chambers just required to wrap up a few loose ends. The bit where I am stumped is 25 down.

The initial letter is unchecked, so could be C or T, but the wordplay has me beaten.

*=anagram, []=dropped, <=reversed.

Across
1	SPECIES – EC in SPIES.
7	EDNA – [wom]AN DE[finitely]<.
11	ARCANE – CAN in ARE.
13	AMEER – A + MEER.
14	COUNTER-ROLL – COUNTER + ROLL.
15	TARPEIA – RAT< + (A1 + EP)<. I don’t think I’d heard of Tarpeia, but the wordplay seemed quite clear.
16	CORRIE-FISTED – CO + (S in TERRIFIED*).
17	SWEET FA – WEE in FAST*.
21	UNGORED – UNDERGO*.
22	IATROCHEMIST – (SO + ARITHMETIC)*.
24	JUNINHO – (IN + H) in JUNO.
26	LEVI-STRAUSS – (TRAVELS + US + IS)*. Claude Lévi-Strauss, rather than the jeans guy.
27	MISOS – O in MISS.
28	PERSIA – PER + SIA[m].
29	PESO – PES[t] + O.
30	NEEDLER – NEED + L[n]ER.

Down
1	SACK – two definitions: bed as in “hit the sack”, plus this sort of thing.
2	PROMO – P + ROMO, a brief fad which I vaguely remember.
3	CANTRED – CAN’T + RED. I can’t quite find a reference for “red” being “to handle match”, but I suspect it’s there somewhere.
4	INTUITIONISM – (N + TUITION) in (I + M).
5	SARAFAN – (A + F) in SARAN.

17	SKI JUMP – JU[ly]in SKIMP.
18	FUCHSIN – SUCH* in FIN.
19	LOMBARD – MBA in LORD.
20	SAULIE – SAU[l] + LIE. In this case, “mute” means a hired funeral mourner.
23	SUSIE – US in SIE.
25	?SAR – Set on invoking special authority.
