 This species differs from the preceding only in heing somewhat 

 more suffused with metallic cobalt-blue on the upper parts, and in 

 haWng the axillaries, under wing-coverts, lower breast, belly, flanks, 

 and under tail-coverts rich deep chestnut ; the thighs are blue, and 

 the under tail-coverts have white tips and obscure subterminal dark 

 bars as in the allied species. BiU black. Wing with the third 

 and fourth primaries nearly equal and longest, second primary 

 generally slightly shorter than the fifth, bastard primary 1"15 to 

 0-8 inch. Legs, feet, and claws black. Length of wing 5-0 to 4-5 

 inches, tail 3--4 to 3-26, culmen 1-0 to 0-9, tarsus 1-2 to 1-1. 



After the autumn moult most of the feathers of the upper parts 

 have pale brown margins (palest on the wing-coverts) and obscure 

 dark-brown subterminal bars. The blue feathers of the underparts 

 are similarly marked, but in the chestnut feathers traces only of 

 the subtei-minal dark bars are observable. Tliese marginal and 

 subterminal bars are cast during March, leaving the male in full 

 breeding-plumage. The female much resembles the autumn plumage 

 of the male, except that the blue of the upper parts is much duller 

 and the whole of the underparts are pale whitish brown, suffused with 

 pale huffish brown on the axillaries and under wing- and tail-coverts ; 

 each feather on the underparts has a dark-brown subterminal trans- 

 verse band, which on the throat is continued on the margins of the 

 feathers ; the axillaries and the under tail-coverts have several 

 transverse dark bars. After the autumn moult the only difference 

 perceptible in the female is that the pale brown margins of the 

 feathers are somewhat longer. Males o/</ie year scarcely differ from 

 adult females, except in having the ground-colour of the underparts, 

 especially on the breast and beUy, tinged with blue. Females of tlie 

 year have the ground-colour of the upper parts brown, only slightly 

 tinged with blue on the wing-coverts, rump, and upper tail-coverts. 

 Young in first plumacje differ very slightly from the females of 

 the year, but have scarcely a trace of blue. ^ 



The Eastern Blue Eock-Thrush breeds in Japan and in the valley 

 of the TJssuri, in North-east China, and in Formosa. It winters in 

 South-east China and the islands of the Malay Archipelago.
