Also diflers from tlip trne P. pii/rici'j>.^ in having the bade of a (hirkcr shade of 

 grey. 



It is somewhat significant tliat these two supposed species of Polioptila sliouhl 

 lie found together at tlie same time of year in tlie same place, and that both sh(]uld 

 differ from their respective types in the same way.

Mr. Sharpe {Gat. Birds B. M., x., p. 361) placed this bird with G. aiirimlari.s 

 Salv., but there are several points of difference. These have been indicated by 

 Berlepsch and Stolzmann (P. Z. S., 1892, p. 374) in comjjaring sj)eciniens from Lima 

 (G. auricidaris) with others from Callacate (fr. ae. perufia/ia). Mr. Baron's 

 specimens seem to agree with the latter.

Several small points of difference seiwrate tliis bird from tlie true B. iiiijricris- 

 tati/s of Colombia and Ecuador, rendering a distinct name necessary.

'' Eyes orange." 



These sjiecimens agree with one of Stolzmaun's in the British Museum from 

 N. Peru. All of them have the feathers of the middle of the crown green at the 

 base and edged with chestnut, producing an occipital patch contrasting with the line 

 of pure chestnut which runs round from the forehead over the eyes and meets on the 

 nape. The true C. contrerasi is described and figured as having the whole summit 

 of the head dark chestnut. The middle of tlie abdomen is strongly snft'used with 

 fulvous. Count Berlepsch, who lias seen one of tliese specimens, thinks it not 

 separable from C. contrcra.'ii.
