By Shirley Palmer, M. D. With the view rather of eliciting and collecting, than of communicating, information on divers obscure parts of Zoology, I propose to give occasionally, in The Naturalist, a sketch of one of the rarer or more curiously constructed animals. My delineations will be taken from the best living or the most per- fectly preserved specimens to which I can obtain access. I shall describe, as •minutely and correctly as possible, the external characters of the subject of the sketch ; and any peculiarities of internal structure, or of economy, which it may be known to exhibit : and most especially shall I feel obliged by the communication of any authentic facts respecting the anatomy, physiology, or habits of such animal, which the experienced observer may be enabled, and have the kindness, to supply. Facts, — not opinions or hypotheses, however novel or specious, — are the only contributions which I crave, or covet, on these subjects. The description of the specific characters and habits of the animal will be followed up, if not preceded, by a sketch of the characters of that genus to which, in my opinion, it has been most correctly referred ; by an enumeration of its synonyms in the leading languages of Europe ; and a reference to the most accu- rate delineations, iconographical or literary, of the animal in question, which I have hitherto seen. For the subject of my First Sketch, I have selected, the Cream-coloured Swiftfoot, Cursorius Isabellinus, — a bird belonging to the Order, Echassiers, Family, Pressirostres, of Cuvier ; and to the Grallatores, Charadriadce, of modern British Ornithologists. VOL. I. b This elegant bird, — le Coure-vite Isabelle, of Temminck, — and Corrione biondo, of Italian writers, was arranged, by Gmelin, in the Plover genus, under the title of Charadrius Gallicus ; and is briefly noticed, but not figured, by Bewick, in his last edition of the History of British Birds, as the Cream- coloured Plover. It was first separated from that genus by Latham, and taken as the type of a new genus, Cursorius ; of which the following are the distinguish- ing characters : Bill shorter than the head ; depressed at the base ; slightly arched and curved, and pointed, at the tip. Nostrils, oval, basal, lateral, and surmounted by a slightly protuberant membrane. Legs long, slender, and naked to some dis- tance above the tarso-tibial joint. Toes three, short; all directed forwards, and united by membrane at their base : interior toe much shorter than the middle toe. Nails small ; that of the middle toe broad, and pectinated on its inner margin. Naked portion of the tibia, front of the tarsus, and upper surface of the toes scutellated. Wings of mean length : first quill-feather almost as long as the second, which is longest. The following is a correct description of a finely-preserved specimen of the adult Cream-coloured Swiftfoot, in the Birmingham Museum of Natural History : Bill black, nearly four-fifths of an inch long. Forehead and crown of the head, pale buff-orange ; changing, on the hind head, into ash- or smoke-grey. (The irides, according to Selby, are pale yellowish-grey). A white streak extend- ing from above the middle of the eye, pointed anteriorly and growing broader as it runs backward, to unite with its fellow at the occiput. Beneath, and in contact with this, a black streak of nearly uniform width, commencing at the posterior part of the eye, and extending to meet its fellow, by an attenuated line on the posterior margin of the white band on the occiput. The occipital angle of the white streak filled up, and bordered to a short distance, by an irregularly- but somewhat cres- cent-shaped patch of black. Nape of the neck bright buff-orange. Whole upper parts of the body sienna-yellow, with an irregularly distributed tinge of ash-grey. Chin, throat, neck, and inferior parts, pale yellowish-white. Quill-feathers deep- brown, bordered at the extremity with buff, and reaching to the end of the tail. Tail slightly rounded, buff-orange : tail-feathers exhibiting, near the tip, a dark-brown patch much more distinctly visible on the inferior than the superior surface. Tail- coverts, above and below, light-grey. Tibiae invested, half way down, with grey feathers. Tarsi pale buff-orange. Toes more dusky. Claws brown. Temminck describes " the young of the year," as exhibiting, on the superior parts, a much clearer yellow colour (isabelle beaucoup plus clair) than the adult bird ; varied, on the scapulars and wing-coverts, by numerous zigzag marks of a deeper tint. The double black streak, — or rather, as I have more correctly de- scribed it, the ordinarily black streak and crescent, — is but faintly marked in bright-brown. Such, at least, are the characters of a young Swiftfoot preserved in the cabinet of Natural History, at Darmstadt. The Cream-coloured Swiftfoot is a native of Africa, especially Abyssinia ; and an occasional visitant only of the southern provinces of Europe. Three instances of its capture in our own island have only yet been recorded. The first specimen was shot in Kent, and sent to Dr. Latham : the second, killed in Wales, found its way into the collection of the late Professor Sibthorpe, of Oxford : the third and last, discovered at Charnwood Forest, Leicestershire, is in the possession of the Rev. Thomas Gisborne, of Yoxall Lodge ; a man equally distinguished by his eloquence as a Christian minister, and by his talents as a naturalist and a poet. Of the food, habits, or nidification of the Swiftfoot, little is, at present, known. The individual, shot in Kent, was observed to run with incredible swiftness, and occasionally pick up something from the earth. It suffered itself to be twice shot at ; and could with difficulty be made to take wing. Its note was unlike that of any known bird.
