Bath have announced the signings of Australian number eight Leroy Houston and Argentina Test prop Juan Pablo Orlandi.
Houston, 26, will move to the Recreation Ground from French club Colomiers. He was a member of the Queensland Reds squad crowned 2011 Super Rugby champions.
And Orlandi, 29, will arrive in the west country from Paris-based Racing Metro, where he has spent the last three seasons.
Bath head coach Gary Gold said: "These are two very significant signings for Bath in that they say a lot about our ambition.
"Leroy is a guy I have admired for a long time, and we are delighted to have secured him. He's very dangerous with ball in hand and loves to hit hard in defence.
"Juan Pablo is also a very powerful man. I spoke personally to the Pumas coach, Santiago Phelan, and he backed up our opinions, telling me that this guy is the real deal."
