name Ccereba Vieillot x can not be used for this group, since the 

 only recognized 2 species mentioned in the original diagnosis is 

 Certhia flaveola Linn., which must therefore necessarily be s the 

 type ; the term Ccereba thus supplanting the more recent Certhiola 

 Sundevall. Caereba of Vigors 3 is merely an emendation, acci- 

 dental or otherwise, of Vieillot's Coereba, and therefore identical 

 in application. Arbelorhina was proposed by Cabanis 4 simply to 

 replace Ccereba,—" Den regelwidrigen Namen Caereba haben wir 

 in Arbelorhina umgeandert." That the same author subsequently 

 sought 5 to restrict Arbelorhina to the group at present under 

 consideration can, of course, not in the least alter the case, and 

 Arbelorhina must be considered a strict synonym of Coereba. 

 As this disposition leaves the Blue Creepers without a generic 

 name 6 , it is proposed that they be called
