Its total area was under 14 sq mi, and the estimated population in 1910 was 2,950 people. The capital was Santa Isabel. The islands are presently part of Equatorial Guinea.

Postage stamps

The colony is remembered by philatelists for having issued its own postage stamps between 1903 and 1910. The first issue depicted a profile of the young Alfonso XIII of Spain, and consisted of 18 values, from 1/4 centimos to 10 pesetas. The values from 1c to 10p were reprinted in 1905, but inscribed "1905".

In 1906, the 1c, 2c, 3c, and 4c values were surcharged 10c, 15c, 25c, and 50c, using a box with the value and "1906". A 1907 set of 16 values updated to a profile of an older Alfonso. Several of these values were surcharged between 1908 and 1910.

Subsequently the island used the stamps of Spanish Guinea.
