so, saying he does not like " ce nam maudit d'icterina." And 

 truly he was right in the change of name, although it was hardly 

 worth the trouble. Eversmann's Sylvia icterina was grounded 

 on the Ficedula icterina of our ' Wirbelthiere Europas/ p. 185, 

 no. 218. In a form differing a little in the structure of its 

 wings fi'oni Phyllopneuste trochilus, I thought that I recognized 

 the Sylvia icterina of Vieillot. Eversmann told me that in his 

 classification he was guided by the short description in the 

 ' Wirbelthiere Europas.^ I possess an original specimen of 

 Eversmann's Sylvia icterina, which fully agrees with examples of 

 that species from Bavaria and Wirtemberg, and can only be 

 ranged with the Ph. trochilus, or close to it. But, whatever may 

 be our opinion as to this species, it has, at all events, nothing 

 in common either with the bird from the Sea of Ochotsk under 

 examination, or with the specimen of the bird described by 

 V. Middendorff killed on the Boganida. I must therefore con- 

 sider my bird from the Sea of Ochotsk, and the birds described 

 by V. Middendorff as the Sylvia [Phyllopneuste] eversmanni, as 

 belonging to quite a new species, which, in opposition to the 

 Javan species standing next to it, I may call Phyllopneuste 

 BOREALis, nov, sp. — It forms, together with the Phyllopneuste 

 javanica, a natural group amongst the Leaf-warblers, distin- 

 guished from the other species by their considerably stronger 

 body, by the bill being stronger and wider at its base, by the 

 yellow band formed by the tips of the greater wing-coverts, by 

 the ends of the quills being slender and distinctly emarginated 

 at their terminations, by the bright yellow, sharply defined tips 

 of the tail-feathers, and by the straight tail. This group may 

 be designated by the name Acanthopneuste, and considered as 

 a subdivision of the other Leaf-warblers. 



The shining yellow spot on the wing, figured by v. Midden- 

 dorff in his 'Travels,' vol. i. pi. 16. fig. 2, forms a half-perfect 

 bright wing-band, and ranges both the species next to the 

 Phyllopneuste proregulus, Pall. (= Motacilla superciliosa. Lath., 

 = Regulus modestus, Gould), which has two yellow wing-bands 

 and similar emarginated tips to the quills. 



These two species may be distinguished in the following 

 manner ; —
