2 Comp. JKSYNS 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."
