Show 1868.] MR. E. P. RAMSAY ON BIRDS FROM QUFAENSLAND. 381 2. On certain New and Rare Species of Birds found at Rockingham Bay, Queensland. By E. P. R A M S A Y , C.M.Z.S. As some of my scientific friends are doubtless aware, I despatched Mr. E. Spalding, an experienced collector, to Rockingham Bay during October 1867, with instructions to procure as complete a collection as possible of all north-country species found in that and the surrounding districts, and particularly to obtain all the information he could respecting the Australian Cassowary (Casuarius australis). The following, then, is a list of the most interesting species found in this locality, and descriptions of such of them as I deem to be new. 1. HALIASTUR LEUCOSTERNUS. This species is common as far south as Port Denison; and a few stragglers have wandered down to the Richmond and Clarence River-heads, New South Wales. 2. ASTUR, sp. Agrees with Mr. Gould's description of A. cruentus, but has no rufous collar. This specimen was accompanied by a young bird, just able to fly, and which coincides with A. approximans exactly. Total length 20 inches; wing from flexure 11, tail 9. 3. ASTUR APPROXIMANS. The above mentioned young bird. There is no difference between the West-Australian and the New-South-Wales individuals of this bird. 4. ASTUR ( $ ), sp. nov. Two specimens shot, both alike. Total length (of skin) 20 inches. Whole of the upper surface dull slaty brown, lower part of hind neck brown. Wings above slaty brown; underneath white, except the tips of the quill-feathers, which are slaty grey; the basal portion of the inner webs of the secondaries and tertiaries barred with greyish brown to within one-third of the width of their inner margin; edges of the wings barred with brown at the base of the primaries. Sides of the head and neck slaty brown, the feathers on these parts being white barred and margined with slaty brown. Whole of the under surface white; the throat, neck, chest, breast, and flanks crossed with wavy bars of brown, broader and inclining to arrow-shaped markings on the breast and flanks. Upper tail-coverts and tail barred with blackish brown; underside of tail-feathers light slate-grey, the bars distinctly showing through on all but the two centre feathers; inner webs of all lighter, becoming-white at the base. Bill jet-black, yellow at the base; cere, legs, and feet yellow, claws black ; irides deep orange. Total length 20 inches; wing from flexure 11*2, tail 8*4; bill, from angle of mouth 1*3, from the forehead along culmen to tip 1*6, |
