Ixxvi INTRODUCTION. 



in New Granada and Ecuador. At Quito, or around those towering mountains immediately under the equator, we 

 find the R, Stankyi and R. Herrani; while Bolivia gives us the R, Vulcani and the R. ruficeps.

I possess two very marked varieties or races of this bird, one being much smaller than the other : the large 

 race, I believe, is from Pamplona, and the smaller from the neighbourhood of Bogota.

I must now ask those who take an interest in the various forms of this family of birds, to turn to my plate of 

 Urosticte Benjamini, and examine the httle bird figured thereon with a beautiful gorget of green and purple. This 

 species is rendered very singular by the two tufts of white feathers which spring from behind the eye, and still 

 more so by the white tipping of the four central tail-feathers. Ornithologists will view this character with 

 astonishment, and inwardly ask, Is this particular mark given for a special purpose in connexion with the economy 

 of the bird, or for the mere purpose of ornament? That ornament and variety is the sole object, I have myself 

 but little doubt. Of this recently acquired form, the single species to which I have assigned the generic name of 

 Urosticte is all that is known. Like so many others that have preceded it, this is an Andean species, its native 

 country being Ecuador.
