Gregor Townsend was without a number of high-profile stars for the June Tests against Canada, United States – who they became the first tier-one nation to lose to – and Argentina due to planned rest and injuries.
Scotland take on Wales on November 3, before home Tests against Fiji, South Africa and Argentina.
Townsend said in a statement: “We now begin the last 12 months of our preparations for Rugby World Cup 2019 with four Test matches in four weeks, a similar challenge to the one we’ll face in Japan.
“We’ve named a 40-man group for this campaign, which highlights the quality of player that is now available to us and the competition for places.
“It also enables us to welcome more players into our training environment and hopefully give a few more players a taste of Test match rugby.
“It’s going to be an exciting year for the squad but our primary focus is fixed on performing well against Wales – familiar opponents who have already recorded a win against us this year.”
Thomson and Skinner are eligible for the national team through family connections, Thomson through his paternal grandfather, Robert, from Wishaw, while Skinner’s father, Peter, is from Ayr.
Skinner (23) was first involved in the then Scottish Exiles (now Scottish Qualified) programme as a teenager, while at Taunton Titans, before he joined the Chiefs in the 2014/15 season.
He was then selected for England U20 – and faced many of his Scotland contemporaries in the age-grade Six Nations – before becoming an increasingly prominent part of the Exeter squad that won the English Premiership title for the first time in 2017 and finished as runners-up in last year’s final.
Thomson (27) arrived in west Wales from Super Rugby side Hurricanes, having represented New Zealand U20 and the Maori All Blacks, and has been a stand-out performer for the Llanelli side in his debut Guinness PRO14 season.
Johnson (25) is eligible for Scotland on residency grounds, having joined Glasgow Warriors in the summer of 2015.
The Australian-born centre has been a popular figure at the Scotstoun club, making 40 appearances since his arrival and voted last year’s Players’ Player of the Season by his peers.
The squad also welcomes the return of several seasoned campaigners who missed the summer tour either through injury or a summer of scheduled rest, which sees the likes of Alex Dunbar, Jonny Gray, Huw Jones, Greig Laidlaw, Sean Maitland, Willem Nel, Gordon Reid, Finn Russell, Tommy Seymour, Ryan Wilson and Hamish Watson all back in the squad.
The selection also marks the return of centre Matt Scott and scrum-half Henry Pyrgos, who last featured in a Scotland shirt in the side’s 2017 wins over Australia in Sydney in June and Edinburgh last November, respectively.
