— o ARSES KAUPI, Gould. Kaup’s Flycatcher. Arses Kaupi, Gould in Proc. of Zool. Soc., December 10, 1850. I nave some little doubt as to the propriety of placing this bird in the genus drses, but rather than multiply the number of genera, perhaps unnecessarily, I have assigned it a place therein, as it accords more nearly with that form than with Monarcha, the only other genus to which it offers alliance. I am happy to have this opportunity of paying a just compliment to my friend Dr. Kaup of Darmstadt, an ornithologist of vast acumen and research, and whose philosophical labours are well known to all naturalists: the compliment is the more appropriate, as he is at this time (1851) engaged in preparing a Monograph of the Muscicapide, to which family the present bird belongs. The specimen here represented is the only one I have seen: it was killed on the north coast of Australia ; and this is all, I regret to say, that is at present known respecting it. Small spot on the chin, crown of the head, lores, line beneath the eye, ear-coverts, broad crescentic band across the back, and a broad band across the breast, deep shining bluish black ; wings and tail brown- ish black ; throat and a broad band across the back of the neck white; lower part of the back and abdomen white, the base of the feathers black, which occasionally showing through give those parts a mottled appear- ance; bill bluish horn-colour, becoming lighter at the tip; feet black. The figures are of the natural size. a ea
