SUMMARYOLSON, S. L. 1977. Notes on subfossil Anatidae from New Zealand, including a new species of pink-eared duckMalacorhynchus.Emu 77: 132–135.A new species of pink-eared duck,Malacorhynchus scarletti, is described from subfossil deposits at Pyramid Valley, South Island, NZ, and is characterized by larger size. Preliminary observations indicate that subfossil specimens ofBiziurafrom New Zealand are larger and differ qualitatively fromB. lobata; for the present, the nameBiziura delautouriForbes, 1892, ought to be retained for the New Zealand form. An erroneous record ofMergus australisis corrected.
