Banco Nacional Ultramarino
In 1906, the "Banco Nacional Ultramarino" took over the issuance of paper money, issuing notes for 5, 10, 20 and 50 rupias. In 1917, notes were added for 4 and 8 tangas, 1 and rupias. These were the only issue of tanga denominated notes, whilst the rupia notes were issued until 1924 and the 1 rupia until 1929. 100 and 500 rupias notes were reintroduced in 1924.
