however, do not hold good when a series from both countries is compared. I have 

 before me 26 Bogota skins of both sexes, 1 (?,2 ? ? from the Cauca valley, 18 adults 

 of both sexes from Cumana, and 14 adults from the Orinoco valley, and fail to see 

 how they can be separated into two forms. There is no difference in the shade of 

 grey on the chest or in the amount of white on the lateral tail feathers between 

 Venezuela and Bogota examples ; nor can they be distinguished in size, as will be 

 seen from the following measurements. I agree, however, with Mr. Ridgway, that 

 this form is quite distinct from P. nigriceps Baird, of Western Mexico, which I had 

 not seen when writing my monograph of the genus.

The females of all these forms {a,— J ) have a distinct black postocular patch, 

 sharply defined against the white or greyish white lower portion of the ear 

 coverts. This dusky auricular patch is altogether wanting in the female of 

 P. nigriceps of Western Mexico.

The S S ad. agree with the type from the Rio Madeira and with a large series 

 from the Orinoco region in having the forehead and crown black, a large, broad 

 white postocular stripe, and by the grey flanks being separated from the rosy red 

 middle of the belly by a distinct white stripe. The ? is also perfectly identical 

 with those from the Caura River. 



G. p. paracusis thus appears to be entirely confined to the Para district, like 

 so many other forms.

This bird fully confirms what I said (I.e.) about the affinities of this "species.' 

 It has the chest even more distinctly shaded with yellowish than the r? from Parti,
