3 Comp. Jenyns Man. of Brit. Vert. Anim. p. 112. "Having compared our 

 English S. Hippolais with the S. rufa of Temminck (the specimen having been named 

 by Temminck himself, and sent by him to Mr Gould, to whose kindness I am in- 

 debted for it), and found them agreeing closely in all their characters, I have no 

 hesitation in considering them of the same species."
