94 Mr. H. Seebohm on the Phylloscopi 



not stand (there being already a Trochilus major of Forster, 

 1817, among the synonyms of P. sibilatrix), I propose to call 

 it PhyUoscopus gaetkei, hoping that future researches may 

 establish its right to be considered a good species upon a 

 firmer basis.
