Clarification of collection data for the type specimens of Hutton's Shearwater Pufftnus huttoni Mathews, 1912, and implications for the accuracy of historic subantarctic specimen data

摘要

Collection information for the type material of Hutton's Shearwater Puffinus huttoni Mathews, 1912, has long been debated. Contrary to some previous studies, we conclude that Sigvard Dannefaerd did not collect the holotype, now in the American Museumof Natural History (New York), nor was it collected in 1894. A more plausible scenario is that Henry Travers shot it off the subantarctic Snares Islands in January 1890. A sole para type of the taxon, previously overlooked in the Natural History Museum (Tring), was perhaps collected in South Australia. Dannefaerd never visited New Zealand's subantarctic region, so several other type specimens supposedly collected by him there in 1894 must also have incorrect collection data.
