This series fully confirms what I said * about the characters of this well-marked 

 form. The five c? c? in the present collection differ from twenty 66 ad. of 

 P. a. aureola from Cayenne, Surinam and Para by having the sides of the head 

 (except a narrow red margin along the upper and posterior border of the ear- 

 coverts), the throat and foreneck pure bright yellow [about cadmium yellow, 

 Bidgw. vi. 6]. Moreover, the forehead, as far as the anterior margin of the eye, 

 is uniform bright orange yellow, and the middle of the abdomen vermilion red, 

 the flanks alone being black. In P. a. aureola there is but a narrow red line 

 along the middle of the belly, and the feathers of the forehead are much darker, 

 more orange-yellow, and broadly tipped with red. 



One of the males (No. 1091) has a white patch on the outer web of the 

 outermost rectrix, just as iu Sclater's type specimen. 



The female, which was unknown hitherto, is indistinguishable from that of 

 P. a. aureola. 



P. a. flavicollis agrees with P. fasciicauda (fasciata anct.) iu the bright 

 yellow sides of the head and throat ; but the latter species is easily recognisable 

 by its yellow abdomen, by the under tail-coverts being yellow with black tips 

 (instead of uniform black), and by the presence of a wide yellowish white band 

 across the tail. 



It appears, however, that /'. a. aureola, I', a.flavieollis and P. fasciicauda 

 are geographical representatives. The range of the first-named form is given 

 in extenso in Ibis, 1906, p. 6, where I also pointed out that specimens from 

 Santarem differ in no way from topotypical Surinam examples. From Itaitnba, 

 on the left bank of the Tapaj6z, about, four or five days' journey south of 

 Santarem, Mr. Hoffmanns sent us I', fasciicauda. Wore information about the 

 distribution on the Tapajoz of these two forms is, therefore, much required. 



P. a.flavieollis is only known as yet from Borba, on the right, bank, and 

 from Hnmaytha, on the left bank of the Rio Madeira. The original locality, 

 Maniios, is most probably erroneous.
