teiized by the paleness of the flanks and the general lighter tone of the 

 under parts, but at present, with only two specimens from that island, 

 I refrain from naming it. I may also mention that a specimen from 

 Tate-Yama, collected by Jouy, October 28, agrees with the Yesso birds. 

 This would not invalidate the status of the latter as a distinct race, 

 since it may be presumed that in winter or during the migrations it 

 may occur in Hondo, especially on the western side. Additional speci- 

 mens from Yesso are therefore very desirable, in order to have the 

 question settled. 



A specimen from Chusan, China (U. S. Nat. Mus., No. 85685), ac- 

 quired by Mr. Jouy at the Shanghai Museum, differs in no essential 

 from the typical Japanese S. amauroUs.
