Uncapped seamers Beth Langston and Kate Cross are in England's 14-strong squad for
their upcoming limited-overs internationals in the West Indies.
Charlotte Edwards's side face a triangular Twenty20 series against West Indies and New Zealand, before playing three ODIs against the Windies.
Four of the
squad - Anya Shrubsole,
Katherine Brunt and Laura Marsh - are injured.
In addition, all-rounder Arran Brindle misses the tour for personal reasons.
The tri-series, which takes place in Barbados, starts on 14 October, with England's first game against New Zealand two days later.

England & Wales Cricket Board
head of women's cricket Clare Connor said: "After an inspirational summer regaining the Women's Ashes, the England team now embarks on a full winter schedule.
"With a few experienced players currently rehabilitating injuries sustained during the Ashes campaign, a number of young players will have the opportunity to play key roles for the side in what promises to be an exciting tour."
England have also named a 21-strong performance squad for 2013-14, comprising the 14 Windies tourists plus Shrubsole, Knight, Brunt, Marsh, Brindle, seamer Georgia Elwiss and batter Fran Wilson.
