Bath have signed Argentina international Eusebio Guinazu and former Scarlets back rower Mat Gilbert.
Guinazu, who covers both hooker and prop, has signed a contract to keep him at The Rec until 2014.
The 30-year-old has 25 caps for his country and has played club rugby for Agen and Biarritz.
Gilbert, 26, made 15 appearances for Scarlets before moving to Mogliano in Italy and has won 11 caps for the England deaf rugby team.
He has been offered a deal at the Premiership club until the end of the season.
Bath head coach Gary Gold said: "Both Eusebio and Mat will be great additions to the squad we have here.
"Eusebio has a huge amount of experience which will be a great benefit to us, whilst Matt is a special young talent with a lot to offer the game.
"They are great guys, will fit in well, and we're looking forward to them joining us."
