34. Pale-eye BROWED Thrush. Turdus obscurus, Gmcl. 



At Amoy I proeui-ed two sizes, large and small, of this 

 winter-wandering Thrush, which strays at that season as far 

 south as Malacca. At Chefoo I procured in May a male of 

 each size. This seems to be the species given by Pallas 

 (Zoograph. Rosso-Asiat. i. p. 457) as Turdus i)allens, and 

 described by him only in the winter plumage, though he 

 states positively that it passes the summer in the copses 

 around the rivers of Dauria, and in the mountain-Avoods 

 around Lake Baikal. Temminck identified certain specimens 

 procured in Europe with Pallas's bird ; then at a later date 

 he confounded T. liallens with his T. daulias of Japan. In 

 Europe, I presume, they have only occui'red in their winter 

 plumage, as they do in Malacca {T. rufulus, Eyton), In 

 spring the head and neck become blackish grey, the chin and 

 upwards to lower eyelid and the superciliary mark being 

 white, the rest of the plumage unaltered. The present is a 

 wandering species ; and its occurrence in Europe is what one 

 might expect; whereas T. daulias is only a local migrant. 

 There is as much as an inch difference in the comparative 

 length of the two races of T. obscurus, and sometimes even 

 more ; but I can find no corresponding difference of plumage 

 to warrant their separation. The light tips to tlie greater 

 wing-coverts, and the white tips to the outer tail-feathers, are 

 by no means constant. Sometimes both are plainly present ; 

 at others, one set, or often both, are entirely absent. 



35. Siberian Thrush. Turdus sibiricus, Pall. 



For some days towards the end of May these Thrushes 

 were about our hills, apparently bound north. On tlie 22nd 

 Mr. Carles shot three males, all sexually well advanced. I 

 took the following note on a fresh specimen : — 



" d. Length 8-5. Wing4-7G; first quill '75 long, second 

 •18 shorter than the tliird and longest, 1-7 short of tail-tip, 

 1-5 longer than tertiaries. Tail 3*5, of twelve nearly equal
