The single example of this beautiful bird, which was procured and presented to me by B. Bynoe, Esq., is I believe all that has ever been seen; I regret to say it no longer graces my collection, having been stolen therefrom, together with some other valuable birds, in the year 1846. Family MERULIDÆ, _Vig._ Genus PITTA, _Vieill._ The members of this genus extend from tropical India throughout the islands of the Indian Archipelago to Australia; one or two species also occur in Africa. Of the three inhabiting Australia the _Pitta Iris_ is figured for the first time in the present work, and is one of the very finest species of this lovely group of birds. 251. Pitta strepitans, _Temm._ Vol. IV. Pl. 1. Since my account of this species was printed I have received its eggs, accompanied by the following notes from Mr. Strange of Sydney:— “I never saw any bird whose actions are more graceful than those of the _Pitta strepitans_, when seen in its native brushes, where its presence is indicated by its singular call, resembling the words ‘_want a watch_,’ by imitating which you can call it close to the muzzle of your gun; no sooner, however, does it commence breeding than it becomes shy and retiring, keeping out of sight in the most artful manner, moving about from place to place, and occasionally uttering its cry until it has drawn you away from the nest. The nests I have seen were placed in the spur of a fig-tree near the ground, outwardly constructed of sticks and lined with moss, leaves and fine pieces of bark; the eggs are four in number,” of a pale creamy-white marked all over with irregularly-shaped blotches of brown and deep vinous grey, the latter appearing as if beneath the surface of the shell; they are one inch and a quarter in length by seven-eighths of an inch in breadth. 252. Pitta Vigorsii, _Gould_ Vol. IV. Pl. 2. I regret to say that up to the present time I have not been able to obtain any information respecting this species, the specimen of which, in the Linnean Society’s Collection, is the only evidence we have of its occurring in Australia; I believe New Guinea to be its true habitat. 253. Pitta Iris, _Gould_ Vol. IV. Pl. 3. Genus CINCLOSOMA, _Vig. & Horsf._ Among the novelties comprised in the present work, there are none more important than the additional members of this genus; three well-defined species being described and figured, of which only one was previously known. The form is peculiar to Australia, and is, I believe, closely allied to my genus _Ianthocincla_, a group of birds confined to India. 254. Cinclosoma punctatum, _Vig. & Horsf._ Vol. IV. Pl. 4. 255. Cinclosoma castanotus, _Gould_ Vol. IV. Pl. 5. 256. Cinclosoma cinnamomeus, _Gould_ Vol. IV. Pl 6.
