England Women have named a squad of 13 for their must-win Kia Women's Test.
Heather Knight (Berkshire, cap)
Tammy Beaumont (Kent)
Katherine Brunt (Yorkshire)
Kate Cross (Lancashire)
Sophie Ecclestone (Lancashire)
Georgia Elwiss (Sussex)
Kirstie Gordon (Nottinghamshire)
Amy Jones (Warwickshire)
Laura Marsh (Kent)
Nat Sciver (Surrey)
Anya Shrubsole (Berkshire)
Lauren Winfield (Yorkshire)
Sarah Taylor (Sussex, wicketkeeper)
Kirstie Gordon - who impressed in last winter's ICC Women's World T20 before picking up a stress fracture - is brought into the squad after taking eight wickets in the warm-up fixture between Australia and England Women's Academy.
England's warm-up game - against Australia A - ended in victory, with centuries for Tammy Beaumont, Amy Jones and Nat Sciver.
Danni Wyatt and Jenny Gunn, who were a part of the ODI squad, will stay with England Women's Academy to take part in T20s against Australia A and Ireland, the latter fixtures a replacement for Ireland's series against Zimbabwe which was cancelled.
Fran Wilson and Alex Hartley will stay with the Test group in Taunton as cover.
England captain Heather Knight said: "It's obviously a very important match for us and we need to win it to stay in the series.
"The beauty of the multi-format points series means we're still very much in the battle, a normal bilateral series that finished like the ODIs would have been finished but we can get back to 6-4 with a win in the Test match and that's exciting.
"The warm-up at Millfield was ideal. We saw batters get runs and spend time in the middle and the bowlers performed well to bowl out the opposition twice on a flat one. We're raring to go again to get back into the Ashes."
