Although the ornithic Fauna of the Quitian Andes shovi^s consider- 

 able resemblance to that of the interior of New Grenada, many birds 

 being common to both these regions, there are a considerable number 

 of species which are, as far as we know at present, peculiar to the 

 former district, and seem to have a very limited distribution. For 

 instances I might mention the curious Capitonid lately discovered 

 by Professor Jameson, Tetragonops rhamphastinus, — the beautiful 

 shining-green Tanager, Chlorochrysa phoenicotis, — and the lovely 

 Humming-bird figured by Mr. Gould in the tenth number of his Mo- 

 nograph of that family under the name Eugenia imperatrix. In the 

 genus Calliste there are at least three species which as yet are only 

 known to occur in the mountain- valleys in the vicinity of Quito, — the 

 Calliste rujigularis, of which a figure has been already given, the 

 present bird, and Calliste lunigera, which was described and figured 

 in the Synopsis of Callistce given in ' Contributions to Ornithology ' 

 for 1851. Like the Calliste rujigularis, the present bird was dis- 

 covered by M. Bourcier during one of his excursions in search of 

 Humming-birds, made in the neighbourhood of Quito, in the valley 

 of Punta Playa. Only two examples, I believe, were brought by 

 him to this country. One of these is in the French National Col-
