296 ^^OTES ON genus pardalotus. 



ingly I should arrange the species somewhat differently from what Mr. 

 Sharpe has done, and propose the following amended 



KEY TO THE SPECIES. 



a'. Cap aud back uniform olive, the feathers slightly margined with dusky. 



P. quadragintus. 

 a*. Cap and back colored diftereutly, the ground-color of the former being black. 

 bK Cap dotted with white or yellow round spots. 

 c'. Forehead concolorous with the rest of the cajj ; supraloral spot white; under 

 tail-coverts yellow. 



dK Enmp chestnut P. punctatus. 



dp. Rump yellow P. xanthopygius. 



c^. Forehead pale fawu, differiug from the rest of the cap ; supraloral spot scarlet ; 



under tail-coverts yellow P. riihricatus. 



5^. Cap without rounded spots, 

 c'. Third (aud often fourth) primaries only edged with white. 



d^. Tii)s of primary coverts yellow P. affinia. 



d^. Tips of primary coverts red P. affinis assimilis. 



c'*. All the primaries edged with white, forming a large wiug-patch. 

 rf'. Cap streaked with white on occiput, and ear-coverts densely spotted with 



white P. orvatus. 



d-. Cap aud ear coverts uniform black. 



e^. Rump dull tawny P. melanocephaliis. 



e^. Rump bright yellow P. uropi/gialis. 



P. quadragintus has been made Xo. 1, as i^robably the most general- 

 ized foim, and next to it is placed P. puncfatus, which in its young 

 plumage shows considerable general resemblance to the green-headed 

 species, and which also in the white round spots on the smaller wing- 

 coverts shows its near relationship. 



The National Museum possesses specimens of the following species : 



p. (juadragintus, 2 specimens. 



P. punctatus, 1.5 specimens. 



P. xanthopygius, 1 specimen. 



P. affinis, 'i specimens. 



P. affinis assimilis, 7 specimens. 



P. ornatus, 3 specimens. 



P. melanocephalus, 2 specimens. 



Si^ecimens of P. ruhrieatus and tiropygialis are, therefore, very desir- 

 able. 



Among the six specimens of P. assimilis is the one brought home by 

 Mr. Peale (U. S. Explor. Exped.) and recorded as P. striatus. 



Smithsonian Institution, March 16, 1886.
