Ptilotis analoga an subsp. ?

N°. 416, (not sexed), Summit of Resi Mountains, 28 August 1907. Iris dark brown, bill black, 

 feet light grey. 



This example much resembles Ptilotis analoga Reichenbach, but is smaller; its upper surface 

 a little darker; chin, throat and breast darker grey with a slight tinge of greenish; bill much 

 more slender. Wing 69, tail 56, bill 14, tarso-met. 19 mm. It differs from Ptilotis jïavir ictus 

 orientalis A. B. Meyer (Journ. f. Orn. 1894, p. 92) by its unspotted and somewhat darker 

 undersurface, as Dr. HARTERT informed me; for the rest it is much like this form, which is 

 named by Messrs. ROTHSCHILD and Hartert Ptilotis analoga orientalis (Nov. Zool. X, 

 1903, p. 441). 



On the Aru Islands, New Guinea and in northern Australia there occurs besides Ptilotis 

 analoga a small, slender-billed, for the rest however similar form, which differs from our bird 

 only by its somewhat lighter upper and undersurface. Whether this is a distinct form [Ptilotis 

 gracilis Gould, Proc. Zool. Soc. 1866, p. 217) or not, is still to be settled. When the two 

 forms are the same, than our bird most likely belongs also to Ptilotis analoga Reichenbach.
