This species would appear to be distributed over the whole of the southern portion of the Australian continent, since it is to be found in New South Wales, South Australia and at Swan River, where it is particularly abundant on the limestone hills near the beach around Fremantle; it is also an inhabitant of Van Diemen’s Land, and all the islands in Bass’s Straits. I have never observed it in collections from the northern coast of Australia, whence I infer that it is confined to those portions of the country mentioned above. In Van Diemen’s Land it is by far the most abundant on the north side of the island, while in the neighbourhood of Hobart Town it is rarely, if ever, seen. Independently of a slight difference in structure, the habits of this bird differ sufficiently from those of the true _Meliphagi_ to fully justify its separation into a distinct genus. In the first place it affects very different localities, preferring to dwell among the trees that crown the low stony ridges, rather than those growing on the lower lands or the brushes; its flight is also very rapid, and, which is rather remarkable for the smaller Honey-eaters, it mounts high in the air, and flies off to a distance with an extremely rapid horizontal and even motion. It is an exceedingly active bird among the branches, clinging about and around the flowers of the _Eucalypti_ in search of food in every variety of graceful position.
