Original: In addition, at various times, it included Aden Colony (from 1858 to 1937), Lower Burma (from 1858 to 1937), Upper Burma (from 1886 to 1937), British Somaliland (briefly from 1884 to 1898), and Singapore (briefly from 1858 to 1867).
Simplified: The colony of Aden came under the same government in India from 1858 to 1937, and so did British Somaliland (now part of Somalia) from 1884 to 1898 and Singapore from 1858 to 1867.
