Scrivens, who captained England to the final of the Under-19s Women's T20 World Cup in January, is joined in the 12-strong squad by a number of her England Under-19s teammates
Grace Scrivens will captain an ECB Development XI against Sri Lanka at Arundel on August 28.
The T20 match will serve as a warm-up fixture ahead of Sri Lanka's white-ball series against England, which will run from August 31 to September 14 and includes three T20Is and three ODIs.
Scrivens, who captained England to the final of the Under-19s Women's T20 World Cup in January, is joined in the 12-strong squad by a number of her England Under-19s teammates, with Liberty Heap, Niamh Holland, Ryana MacDonald-Gay, Charis Pavely, Davina Perrin, Lizzie Scott, and Alexa Stonehouse all selected.

South East Stars duo Charlotte Lambert and Jemima Spence, who were both non-travelling reserves for the Under-19s World Cup, have also been included in the squad alongside 19-year-old Central Sparks bowler Hannah Hardwick.
At 23, Eva Gray is the oldest player in the squad. The right-arm seam bowler has taken 14 wickets across all formats for Sunrisers and Oval Invincibles in 2023.
England Women head of performance pathways, Richard Bedbrook, said: "The clash with The Hundred finals stages means a number of players aren't available for selection for this one-off fixture and, as such, steering the team towards an ECB Development XI, rather than an England pathway team, allows us more flexibility with selection.
"We have looked to involve a group of younger players who are all progressing within their regional teams and this game provides all selected with an opportunity to experience playing against senior international opposition."
