This bird^ closely allied to the Grassliopper Warbler^ 

 so well known to the naturalists of Great Britain, was 

 introduced into the European Fauna by Pallas, in his 

 "Fauna Rossica," as Turdus certhiola, and was described 

 by him afterwards under the name of Motacilla certhiola. 

 It was subsequently introduced into the Manual by 

 Temminck as Sylvia certhiola, who has giYcn a very 

 clear description of the bird, and a careful comparatiYe 

 diagnosis between it and Locustelle.
