" Both sexes are of the same dimensions. Total length 5-5 inches 

 wing 3-5, tail 2-8, tarsus 0-S, bill from forehead 0-5, from nostrils 

 O-So, trom gape 0-7. 



_ ;' This species is undoubtedly closely allied to P. faUata of Gould ; 

 It is however, slightly smaUer, and wants the rufous under surface 

 ot that species, and may at once be distinguished from it by having 

 the pectoral hand extendinrf upivards to the base of and joining to 

 the ear-coverts, which Mr. Gould distinctly states is not tlie case m 

 his P falcata" 



Besides the differences pointed out by Ramsay, P. pallida has 

 the lower portion of the ear-coverts black, these parts being in 

 P. falcata brownish grey.

Adult male. Besides its smaller size, this species differs from 

 the male of P. fcdcata only by the colour of the plumage of the 

 chest and fore neck; it has on the fore neck a rather narrow cres- 

 cent ot black : which runs across the lower throat and joins the 

 blacl- ear-coverts ; below this black coUar is a second but indi- 

 stinct band of pale grey, and the flanks are also slightly washed 

 with grey : upper border of the eyes and lores bluish grey, like the 

 top ot the head ; " eyes reddish brown " (Brenchlei/). 



Adult fe.nale. I cannot find any difference in plumage between 

 the females of P. xantherythrcea and P. fcdcata. " Maxilla horn- 

 colour ; mandible orange; feet silver-grey; iris dark fawn"
