Yoshi-goi, Jap.
Male ad. (Japan). Crown, hind-neck, back, scapulars, and inner second¬aries rich dark chestnut, the crown darker and slightly washed with grey ; quills dull slaty grey ; wing-coverts buffy ochreous, the edge of the wing and the tail deep chestnut ; chin and throat white, tinged with isabelline, and with a dark central line ; rest of under parts creamy buff ; pectoral feathers elongated, and concealing feathers blackish, margined with ochre¬ous ; bill blackish brown above, yellowish brown below ; orbital skin purplish flesh, tinged with green ; legs grass-green, yellow near the tarso-tibial joint, and on the soles ; iris straw colour. Culmen 2.0, wing 5.5, tail 1.65, tarsus 2.1 inch. The female differs in having the head, neck, and upper parts rich chocolate-red, spotted with creamy white, and the under parts isabelline, striped with warm chocolate-red and blackish brown.
Hab. Eastern Siberia (southern Dauria, the lower Amoor, the mouth of the Ussuri river, and the island of Askold) Japan ; China to Borneo and Celebes.
In general habits and nidification it does not differ from A. cinnamomea, with which it was confused by the earlier Siberian travellers. Its eggs from Dauria are described as being white, almost elliptical in shape, and measure about 1.30 by 1.06.
Ardetta sturmi (Wagl) which inhabits the greater part of Africa is said to have occurred in the Pyrenees, but I find no authentic instance of its occurrence within our limits except that of one individual at Laguna in the Canaries, and con¬sequently do not include it.
