Cettia cantillans (Temm. & Schl.). 



The bird which ia my former list was called " Phyllopseustes xantho- 

 dryasl^P^on the authority of Mr. Xamiye, has now come to hsmd, aud 

 belongs undoubtedly to Cettia cantillans. 



The two Cettias inhabiting Japan afford the most extraordinary^ ex- 

 ample of two distinct species which are absolutely identical in ev^ery- 

 thing, except size, inhabiting the same country. They do not seem to be 

 local representatives of each other, yet there can be no doubt as to their 

 distinctness. 



One specimen was collected by jMr. Xamiye at Napa, Okinawa Shima, 

 March 8, 188G. 



Another was collected by Mr. J. Nishi on Yayeyama Island, and the 



measurements of both specimens are included in the following table :

Cettia cantans (Temm. & Schl.). 



Mr. Pryer {in litt.) informs me that he has winter specimens from 

 Liu Kiu. It is not at all likely that he should confuse it with the fore- 

 going species.
