638 BIRDS FROM TOKYO, JAPAN STE.TNEGER. 



For compavison with A\ cafitatwurps I havo four males colloctod ;it 

 Fusaii, Korea, by Mr. I\ L. ,Tony during!: January, April, and May. It 

 is evident from this nuiterial that tlie Korean birds differ from E. ciop- 

 sis, of which I have ten males at hand, in se^-eral other i)oiuts in addi- 

 tion to havinji; the ear eoverts brown instead of bhick. Thus, the top 

 of the head is at all seasons less mixed with blaekish, and the rump is 

 eonsiderably i)aUM'. In botli respoets the Tsushima birds agree elosely 

 with the birds from the other .Japanese Islands. It is, therefore, en- 

 tirely out of the question to refer them in any way to U. casta uciceps. 

 On tlu' other hand, as pointed out by Dr. Ijuna, they ditfer from 

 typi<'al E. ('i()2>sis in the amount ot the brown on thenar eoverts. True, 

 some winter birds IVom flai)an jaoper nuiteh the least marked Tsu- 

 shinui birds of a later date, but in tho former the brown disappears as 

 the season advances, while in the latter it appears to be permanent. 



Under these circumstances it seems best to recojiiiize the Tsushima 

 form as a sei)arate race, which may be characterized as Iblhtws: 



I'Jmlhriza riopsis iJiiiKv, suhs]). nov. (Mosely allied to l^'mhcriza ciopsis, 

 but the ear-coverts brown in the male duiinii' the breedinji" season in- 

 stead of black.
