China's Dong Cheng, Morocco's Mahjouba Oubtil, Romania's Mihaela Lacatus and Queen Underwood of the USA have received wild card entries to the Olympic Games in Katie Taylor's lightweight class.
The quartet join Taylor and seven other boxers - all of whom qualified outright for London games in the lightweight category at last month's AIBA World Women's Championships in China - to complete the 12-strong female lightweight division at London 2012.
Taylor, who claimed her fourth World title in-a-row in China, will be seeded at the Olympics and will receive a bye into the quarter-finals.
World amateur boxing chiefs AIBA confirmed their full list of 250 male and 36 female boxers for the 2012 Games.
Women's boxing will be making a debut in London in three weight categories; flyweight, lightweight and middleweight.
Meanwhile, the Irish Elite squad - including the six-strong Olympic team - will meet India and Tunisia in a Test Match at Dublin's National Stadium on Friday.
All three nations met in a Test Match at the National Stadium on Wednesday. No scores were recorded.
