''Iris dark; bill brown, base of lower mandible fleshy; 

 feet deep fleshy.^'— C. B. K. 



This extremely rare Rock-Thrush, which breeds in northern 

 and eastern Siberia and northern China, appears to winter 

 in Indo-China, and is occasionally, though rarely, met with in 

 the Malay Peninsula. The present specimen is quite imma- 

 ture and has the upper surface earthy-browu with no tinge 

 of bluish-grey, but is undoubtedly referable to this species. 



Tiie dimensions are : wing, 94; tail, 69 ; tarsus, 24 mm.

" Iris dark ; bill leaden black or black ; feet black or sooty. 

 The two island s])ecimens came from, the rocks of the shore, 

 that from Lem Ngop was shot on the top of the white-painted 

 wooden lighthouse, where it had a regular perching spot.'' —

Birds from the Malay Peninsula or Indo-China are very 

 variable, some specimens having no chestnut whatever in the 

 pelage, while in others almost the entire abdomen, axillaries, 

 and under wing- and tail-coverts are chestnut-red. Probably 

 both the western form M. solitarius solitarius and the eastern 

 M. s. j)hilippensis yvmier m the region. Nearly all the birds 

 met with are more or less immature.
