Russell is one of four players who will go to a third World Cup, along with locks Grant Gilchrist (33) and Richie Gray (33) and front-rower WP Nel (37).
Coach Gregor Townsend did not spring any major surprises in naming his squad, the announcement coming four days after Scotland’s 30-27 loss in a warm-up test in France.
The selection for France is made up of 19 forwards and 14 backs.
Forwards Ritchie, Zander Fagerson, George Turner, Scott Cummings and Hamish Watson are also back for another tilt at the World Cup, as are backs Darcy Graham, Chris Harris, Blair Kinghorn and the scrumhalf pair of George Horne and Ali Price.
First choice scrumhalf Ben White is included despite injury concerns.
McInally, Murphy Walker, Josh Bayliss and Jamie Dobie are the four players cut from the 37-man training squad. McInally, who won 49 caps, retires from rugby in November to become an airline pilot.
Fullback Stuart Hogg, who won 100 caps for the country, is absent after announcing his surprise retirement last month, saying his body could no longer take the strain.
Gray is the most-capped member of the squad with 75, while former Ireland under-20 international Ben Healey is the least experienced with only two caps after making his debut in March.
Huw Jones, who was a surprise omission four years ago, is in the squad this time round and expected to be a starter when Scotland take on holders South Africa in their first match in Marseille on September 10th. They also face Tonga, Romania and Ireland in Pool B.
The Scots will have a final warm-up test against Georgia at home next week before heading to France.
