48 BONELLl's WAEBLER. 



and tail are black grey; lesser wing coverts bordered 

 with greyish yellow green; wings brown, with the pri- 

 maries bordered with bright yellow green; cheeks grey; 

 from the nostrils a clear white stripe over the eyes. 

 The whole of the under parts of the body clear shining 

 white, washed with greyish on the crop, and yellow on 

 the flanks; tail of a lighter brown than the wings, the 

 upper three-fourths of the quills edged with greenish 

 yellow; beak brownish above, under greyish yellow; 

 feet brownish or dark grey; iris reddish brown. 



The female has the white less clear below. Before 

 the first moult the young birds are reddish ash-colour 

 above, silky white below, with the sides of the chest, 

 the flanks, and the under tail coverts, bright russet; 

 cheeks and sides of neck bright reddish ash-colour; 

 wing coverts, primaries, and tail quills edged with bright 

 greenish yellow. — (Degiand.) 



My figures of this bird and its egg are from specimens 

 sent me by M. E. Verreaux. 



Figured also by Temminck and Laugier, pi. col. 24, 

 f. 2. Koux, Ornith. clu Dauph., pi. 226. Gould, B. of 

 E., pi. 131. Bouteil, Ornith. du Dauph., pi. 26, f. 7. 



Another Le^ Warbler, Sylvia horealis, Blasius, (the 

 Sylvia enersmanni of Middendorff",) has lately, on the 

 authority of Professor Blasius, been added to the 

 European list. (Vide Naumannia, 1858, and Ibis, No. 

 4, p. 459, 1859.) This interesting Asiatic species, which 

 has been taken in Heligoland by Herr Gatke, ought to 

 follow the last species in this work; but in the absence 

 of authentic specimens, from which to take my figure, 

 I must unwillingly defer a notice of it for the present.
