Crystal Palace have signed Reading defender Adrian Mariappa and Aston Villa midfielder Barry Bannan.
Mariappa, 26, joins ex-Reading team-mate Jimmy Kebe, who signed a deal on Saturday evening, and the Jamaica international became Holloway's 13th signing of the window.
“I'm delighted to be joining Palace and playing in the Premier League again. It’s something everyone dreams of doing,” Mariappa, who signed a three-year deal, told the club's official website.
“Selhurst Park is always a great place to play -- the atmosphere has always been amazing and I've had some great games against this club.
“I want to prove I can play at this level, and I'm sure that will be the same for everyone in the squad as we aim to stay in the Premier League.”
Meanwhile, Scotland international midfielder Bannan has arrived from Aston Villa, with the 23-year-old signing a three-year deal.

He played for Palace boss Ian Holloway during a loan spell at Blackpool and told Palace’s official website he was looking forward to the challenges ahead in South London.
“It is a big move for me to leave Villa, and I would like to thank the fans there -- but it's a new chapter in my life now and I can't wait to get started,” he said. “I want to get myself in the door and start training and hopefully get myself in the team.”
Palace have also allowed defender Peter Ramage to join Barnsley on a season-long deal.
