The small differences noticed by Hellmayr and Seilern * as existing between 

 Venezuelan skins (Nos. 1 3) and two undoubted P. ophthalmicus (Nos. 11, 12) 

 are not borne out by the larger series which came to hand since our remarks were 

 written. It is true, the two examples from the Cauca River, including the type of 

 P. alleni, agree with the Cambre birds in the light cinereous pileum, clear yellowish 

 green back, bright sulphur-yellow colour of the anterior auricular region, and in the 

 lesser extent of the whitish chin-spot, as contrasted to the two specimens in the 

 Berlepsch Collection (Nos. 11, 12); but the series from Ecuador shows considerable 

 variation in all these characters, and the Bogota skin (which would be expected to 

 belong to the pale northern race) is fully as dark as the Huambo bird (No. 11). 



In the adult male from Pichincha (No. 7) and the immature one from Coraz6n 

 (No. 8) the anterior auricular region is white, scarcely shaded with yellowish, as in 

 the Huambo specimen (No. 11), while in the two others from the same localities 

 (Nos. 9, 10) it is even more deeply olive-yellow than in the Cumbre and Cauca 

 examples. The crown is light cinereous in No. 9 (Corazon), as in the latter, but very 

 dark slate-grey in No. 7 (Pichincha), while the others are intermediate. As to the 

 colour of the back, only one of the Ecuadorian skins (No. 8, Corazon) matches 

 those from Venezuela, but the three others are also decidedly lighter green than
