* Mr. Gatke has in his collection a bird allied to Hypolais icterina, and 

 which he considered to be identical with Sylvia japonica. He describes

 kind of delicate yellow." It appeared to me to be closely allied to Hy- 

 polais icterina. It has the blue legs of Hypolais ; and there is a rather 

 broad and vei'y distinct lightish band on the wing.
