Specimen collected by Robert Falcon Scott's British Antarctic Expedition 1910-1913, also known as the Terra Nova expedition. It had a broad scientific programme and collected thousands of geological and zoological specimens. This species of seabird breeds on the island of Trindade, off Brazil. Previously known as South Trinidad, it was one of the stops made by Terra Nova on its voyage south. This specimen was prepared by Wilson, the expedition's chief of scientific staff, in July 1910.
