" Iris dark brown, feet and bill black, base of mandible brown." 



On receipt of these specimens it at once occurred to me that 

 they might represent some phase of S. 2M7-amhai, originally 

 described from nn adult male in the Tring Museum; and the 

 careful examination of the typical example not only confirmed 

 the correctness of my surmise, but, furthermore, clearly showed 

 that S.2)arcmibce is merely a western, smaller subspecies of Elcenia 

 cinerea. 



In fact, on comparing the types of the two "species" I find 

 them identical in structural characters as well as in coloration. 

 However, E. c. jyarambce may be recognized by its much shorter 

 wings and tail, and by its rather slenderer, shorter bill. 



The immatui-e males obtained hj Mr. Palmer diff"er from the 

 type in the following points: — The back is bright olive-green 

 instead of bluish grey ; the tips to the upper wing-coverts ami 

 edges to the secondaries are pale yellow, instead of white, the 

 edges to the rectrices olive-green, not cinereous. Moreover, 

 the throat only is white, while the remaining under parts, 

 including axillaries and under wing-coverts, are pale yellow, with 

 obsolete, greyish-white flammulations on the chest. The vertical 

 patch, in no. 2494, is white Avith a hardly perceptible yellowish 

 hue in its posterior portion, the rest of the pileum ashy grey, as in 

 the adult male, but slightly darker. 



The immature birds are not unlike the corresponding stage of 

 E. c. cinerea*, but can easily be distinguished by having the 

 pileum ashy-grey (not olive-green like the back), the coronal patch 

 white (instead of pale yellow), and the under parts much paler 

 yellow, with the throat conspicuously white. The bill is also 

 narrower and shorter. 



E. c. parambcK evidently replaces E. c. cinei'ea on the western 

 sides of the Andes in Ecuador and Colombia. 



For comparison, the dimensions of seven skins of E. c. cinerea.
