The male of tliis form is a small edition of P. ntttrolain, Imt the females before 

 us lack all traoes of nifons. We are convinced that all the Pachycephala of the 

 melamirn-astrohihi groups are subsj.ecies of a single species, bnt we hope to treat 

 more fnllv on the subject of this and similar cases later on, and so for the present 

 make nse of binomials.
