All the upper surface brownish olive, tinged with yellowish olive on the margins of the feathers; outer webs of the primaries and tail wax-yellow; inner webs brown; under surface of the wing and tail yellowish buff; stripe over the eye to the back of the neck black; ear-coverts dark grey; below the ear-coverts a stripe of bright yellow; throat and under surface yellow, becoming paler as it approaches the vent, each feather with a stripe of brown down the centre. The Plate represents the bird in two positions of the natural size. [Illustration: PTILOTIS FLAVIGULA: _Gould_. _J. Gould and H. C. Richter del et lith._ _Hullmandel & Walton Imp._ ] PTILOTIS FLAVIGULA, _Gould_. Yellow-throated Honey-eater. _Ptilotis flavigula_, Gould in Proc. of Zool. Soc., Part VI. p. 24; and in Syn. Birds of Australia, Part IV. This fine and conspicuous species of _Ptilotis_ is abundant in all the ravines round Hobart Town, and is very generally dispersed over the whole of Van Diemen’s Land, to which island I believe it to be exclusively confined, for I neither observed it myself nor have I met with any example in the numerous collections I have received from South Australia and New South Wales. It is very animated and sprightly in its disposition, extremely quick in its actions, elegant in its form, and graceful in all its movements; but as its colouring assimilates in a remarkable degree with that of the leaves of the trees it frequents, it is somewhat difficult of detection. When engaged in searching for food it frequently expands its wings and tail, creeps and clings among the branches in a variety of beautiful attitudes, and often suspends itself to the extreme ends of the outermost twigs; it occasionally perches on the dead branches of the highest trees, but is mostly to be met with in the dense thickets. It flies in an undulating manner like a Woodpecker, but this power is rarely exercised. Its note is a full, loud, powerful and melodious call. The stomach is muscular, but of a very small size, and the food consists of bees, wasps and other Hymenoptera, to which are added Coleoptera of various kinds, and the pollen of flowers. It is a very early breeder, as proved by my finding a nest containing two young birds covered with black down and about two days old, on the 28th of September.
