The tour of North and South America will provide an opportunity for those players to gain their first taste of international rugby in the matches against Canada, USA, Chile and Uruguay scheduled to take place next month.
Zander Fagerson, Grant Gilchrist, Richie Gray, Finn Russell, Jack Dempsey and Darcy Graham are among the senior players who have been left out, along with France-based pair Ben White and Blair Kinghorn and the Japan-bound George Turner.
However, Duhan van der Merwe, Matt Fagerson, Huw Jones, Pierre Schoeman, Jamie Ritchie, Rory Darge, Kyle Steyn, Scott Cummings and Sione Tuipulotu have all been selected, ensuring an experienced core remains within a largely experimental group.
Here are the 10 new faces in the squad:
