In addition, there are a number of species and genera that are either intermediate between the otherwise well- defined tribes (e.g. Coscoroba) or too poorly known for a safe classi- fication (e.g. Anus specularis, Anus leucophrys, Malacorhynchus, Tachyeres) ; others show peculiarities or a combination of characters that prevent them from fitting well into any of the existing groups. Such genera as the Australian Cereopsis, Anseranas, Stictonetta, and Chenonetta could either be made the sole representatives of so many separate tribes or each could be included in the tribe with which it shares the greatest number of similarities. For the sake of con- venience we have adopted the latter course, but without forgetting that these genera are not typical representatives of the tribes with which we associate them.
