Gold-fronted Euphonia {E. flnvifrous). The male of this species 
is somewhat similar to the females of the preceding species, especially 
selateri, but the colours are brighter and more lustrous, the yellow 
areas especially being larger and more pronounced in hue, also the 
olive-greens are richer and more glossy than is the case with any 
female Euphonia. 
Two specimens of this species were presented to the London 
Zoo in 1889, but I cannot trace any other importations of living 
specimens.

and richer on the upper surface ; rump, yellowish olive-green ; fore-

green ; bill, blackish-brown colour ; legs and feet brownish, Total 
length 4j inches, tail If.
