_J. Gould and H. C. Richter, del^t_ _C. Hullmandel Imp._ ] ARTAMUS SUPERCILIOSUS, _Gould_. White Eye-browed Wood Swallow. _Ocypterus superciliosus_, Gould in Proc. of Zool. Soc., Part IV. 1836, p. 142; and in Syn. Birds of Australia, Part I. fig. 2. There is no species of _Artamus_ yet discovered to which the present yields the palm, either for elegance of form or for the beauty and variety of its plumage; the only known species with which it could be confounded is the _Artamus rufiventer_, an Indian bird with the breast similarly marked, but which is entirely destitute of the superciliary stripe of white, which has suggested the specific name; in this character and in the rich chestnut colouring of the breast, it differs from every member of its tribe inhabiting Australia. I am unable to say what is the extent of its range, but I am induced to believe that it is confined to Australia, and that in all probability it seldom leaves the interior of the country; the extreme limits of the colony of New South Wales, particularly those which border the extensive plains, being the only parts where it has yet been observed. I first met with it at Yarrundi on the Dartbrook, a tributary of the Hunter, where it was thinly dispersed among the trees growing on the stony ridges bordering the flats. From this locality to as far as I penetrated northwards on the Namoi, as well as in the direction of the River Peel, it was distributed in similar numbers, intermingled with the _Artamus sordidus_, at about the ratio of one hundred pairs to the square mile, the two species appearing to live and perform the task of incubation in perfect harmony, both being frequently observed on the same tree. In their dispositions, however, and in many of their actions they are somewhat dissimilar; the bird forming the subject of the present Plate being much more shy and difficult of approach than the _Artamus sordidus_, which is at all times very tame; it also gives a preference to the topmost branches of the highest trees, from which it sallies forth for the capture of insects, and to which it again returns, in the usual manner of the tribe. In every part where I have observed it, it is strictly migratory, arriving in summer, and departing northwards after the breeding-season.
