194: TIJEDIDJE. 



This Thrusli is nearly allied to the preceding, but is perfectly 

 distinct from it, differing both in size, colour, and wing-formula. 

 The upper parts arc of a richer olive-brown ; the spots on the 

 greater and median ■\ving-covcrts are much more conspicuous, the 

 terminal spot being nearly pure white, and the subterminal band 

 nearly black ; the ear-coverts and the feathers of the cheeks 

 have very conspicuous black terminal bauds, which form a crescent 

 on each side of the neck. The spots on the underparts are also 

 larger, broader, and darker in colour ; and the axillaries and under 

 wing-coverts are of a darker buff. The most important difference 

 is, however, to be formd in the wing-formula, the third, fourth, 

 and fifth primaries being nearly equal and longest, whilst the 

 second primary is very little longer than the seventh. This species 

 is slightly larger than the preceding. Length of wing 4-7 inches, 

 tail 3'8, culmen 0-9, tarsus 1'37, bastard primary 0*9. 



The femnle does not differ from the male. Birds of the year and 

 ijoung in first plumage appear to be unknown. After the autumn 

 moult the general colour of the upper parts is slightly more ochra- 

 ceous. 



Pere David's Thrush appears to be a resident in Northern and 

 "Western China. 



The British Museum docs not possess an example of this species ; 

 but I have examined sjjecimens in the museums of Paris and St. 

 Petersburg.
