Frederick Wollaston Hutton (1836–1905) was a geologist and a supporter of Darwinian theory. He emigrated to New Zealand in 1866, became Professor of Biology at Canterbury College, and won awards both in Britain and Australasia for his work on the natural history of New Zealand. He published scientific papers on biology and zoology as well as geology and, with James Drummond, wrote two popular works, Nature in New Zealand (1902) and The Animals of New Zealand (1904). The latter was extremely successful. It was revised and expanded the following year, and this fourth edition was published in 1923. The book focuses on native vertebrates, so the bulk of the content relates to birds, of which Hutton had published a catalogue in 1871. It also describes marine mammals, reptiles, and bats, and gives brief coverage to introduced species. There are 154 illustrations, and indexes of Maori, English and scientific names.
