The island of Nias, the largest of the long series of islands flanking the west coast of Sumatra, and situated at a distance of about 70 miles from the north-west coast of the latter, has, of late, more than once been the subject of zoological investigations. The first intelligence about the avifauna of Nias is due to a visit, paid to that island by Baron von Rosenberg, in 1854. The results of his investigations are published in the Verhandelingen van het Bataviaasch Genootschap van Kunsten en Wetenschappen, Vol. XXX (1863) under the title: Verslag omtrent het eiland Nias en deszelfs bewoners, door J. T. Nieuwenhuisen en H. C. B. von Rosenberg. This report contains, on pp. 19 and 20, a list of 50 species of birds without any further details. Several of these names I was not able to identify with any of the known Malaiasian species, and of others the identification I ventured in the following list is subject to some doubts.
