Show 140 MR. R. SWINHOE ON CHINESE PLOVERS. [Mar. 10, Winter plumage.-Light brown above, with a rufous tinge on the sides of the head. A narrow band of white runs across the forehead and over to the top of the eye; it then turns rufous, and so passes over the ear-coverts. The loral streak is light reddish brown. The nuchal white ring is indistinctly indicated, being marked with light rufous, which is also the colour of the breast-patch, and runs faintly across the breast. The rest of the under parts are white; and the wings and the tail have the same markings as in the adult. Section II. Red-breasted. 6. JEGIALITES MONGOLUS (Pall.). Charadrius mongolus, Pall. Reise, iii. p. 700. Charadrius mongolicus, Pall. Zoograph. ii. p. 136. On the South-China coast this bird is a rare winter visitant; but in Hainan I found small parties of them on two occasions in March 1868, and procured two examples in winter dress. In May of the same year numbers of them were exposed in the market at Shanghai in summer plumage ; I preserved one. The Hainan and the Shanghai birds agree, and are doubtless of the same species, and identical with the bird which Middendorff met with in large flocks on the 30th of June in the neighbourhood of the debouchement of the River Uda into the Sea of Ochotsk (see Midd. Reise, 1843-44, p. 211). Our bird answers well to his description and plate. He recognizes this species as distinct from Ch. pyrrhothorax, Temm., of Russia, and from Ch. asiaticus (caspius), Pall., and adds (p. 212) that the longer tarse of the latter (39 millims.) makes it easily distinguishable in any dress from the JEg. mongolicus. I will here give a description of m y Hainan and Shanghai birds. JEg. mongolus (Pall.). Winter plumage. Hainan. Upper parts light greyish brown. Loral streak, ear-coverts, and latero-pectoral patch more or less marked with brown. A faint brown bar runs across the breast. Forehead, eyebrow, chin, throat, and under parts white. Wing hair-brown; lower edge of joint, broad margins and tips to greater coverts, margins to secondaries broadening inwardly, basal halves of outer webs of sixth and remaining primaries, first quill-shaft entirely, the others more or less, white. Upper tail-coverts : central feathers light brown margined with white, the side ones pure white. Tail: first or outer rectrix white, with an oblong longitudinal spot of pale brown on the inner web; second light brown, with white shaft and tip ; the rest darker brown, with brown shafts and white tips, the white decreasing on the two centrals. Bill black. Legs deep blackish grey, claws black. Length of wing 5*4 inches ; tail 2*5 ; bill in front *75 ; tarse 1 * la ; middle toe (claw '17) '85. In summer (Shanghai specimen) the upper parts deepen in colour. A light rusty chestnut-colour marks the upper forehead, runs round the crown, and forms a broad nuchal collar extending across the breast and colouring the greater part thereof. The white of the |
