The sexes are alike in plumage, but the female appears to have a greater extent of olive-brown on the flanks and sides. In actions and habits they closely resemble the R. albiscapa of New South Wales, being seldom seen in the " opens," usually confining themselves to the dense brushes and thickly wooded parts. The above described new species were discovered by Mr. Charles Pearce in the Fiji Islands ; and now form part of the magnificent collection at Elizabeth Bay. I am indebted to Mr. William Macleay, F.L.S., for the privilege of describing these new and interesting forms. Mr. Brazier exhibited six rare species of Cyproea ( Walkeri, staphyloma, limacina, miliaris, quadrimaculata, and asellus) from Darnley Island, and a new Helix from Hall Sound, New Guinea.
