Coach Mark Robinson said: "In selecting this squad, we've had the opportunity to consider our England Women's Senior Academy fixtures against South Africa and New Zealand and it's heartening to see so much competition for places.
"We saw some excellent individual performances in those games - Sophia Dunkley hit 91 against New Zealand, Emma Lamb and Freya Davies have bowled well and Bryony Smith made an outstanding 92 yesterday against South Africa.
"There’s a growing number of players beginning to make cases for selection which is a reflection of the depth that’s starting to emerge and that’s exciting."
