On the local distribution of some Tasmanian animals

Many of the Fellows of this Society must have noticed the absence (till lately) from our suburbs of the black and white or whistling Magpie (Gymnorhina organicum), the Miner (Myzantha garrula), and the Rosella parrot (Platycercus eximius). From the earliest days of Hobart Town till a few years ago, these three birds were unknown, as residents, on the Hobart Town side of the Derwent, from Glenorchy to the Huon, although much of the country lying between these places is apparently similar to that inhabited by the same birds at a distance. So marked was this absence in the case of the Magpie and Rosella that Mr. Gould, the celebrated ornithologist, specially refers to it in his recently published handbook on the birds of Australia
