grisola] as the skill is preserved in the Canterbury Museum it 

 is imperative tliat a re-examination be made and the identity 

 of the bird fixed. BuUer^s nomination was purely guess-

 been published. 



MAORIGERYGONE, gen. nov. 



Differs from Pseudogerygone in the extremely compressed 

 bill, much longer tail, different wing formula, the fifth 

 primary longest, and different style of coloration. 



Type : Curruca igata Quoy & Gaimard, 



Note : — Gerygone was introduced by Gould to replace 

 Psitopus (preoccupied), proposed for P. albogularis Gould. 

 Sharpe separated the somewhat heterogeneous assemblage 

 into Gerygone and Pseudogerygone, the type of which latter 

 he named G. personata Gould, and thereto attached the New 

 Zealand birds. It is now necessary to subdivide Pseudo- 

 gerygone, as the birds thereunder included have different 

 structural characters as well as varied coloration. The New 

 Zealand species are easily differeutiated as above.
