Glasgow Warriors supply eight of the new squad members in Jon Welsh, Dougie Hall, Tom Ryder, John Barclay, Sean Kennedy, Alex Dunbar, Peter Horne, Peter Murchie.
The other players are: Alasdair Dickinson, Richie Vernon (both Sale Sharks), Grant Gilchrist (Edinburgh), Tom Heathcote (Bath) and Nikki Walker (Worcester Warriors).
The Scotland team to play Ireland will be announced on Wednesday.
