There is a region in South America that has as yet been but superficially investigated, either by the per- 

 severing and forward-pressing collector, the scrutinizing man of science, or those pioneers of discovery, 

 the devotees of religion. This country, vast in extent, covered with great primaeval forests, and watered by 

 hundreds of the tributary streams which serve to form the great rivers of the inner sides of Columbia, Peru, 

 and Bolivia, teems with animal life : by the inner side, I mean the eastern dip of the great Andean and 

 Cordilleran ranges, or, to speak more pointedly, the sources and tributaries of the rivers Amazon, Madeira, 

 and Negro. In this vast region, extending for at least six degrees of latitude on each side of the 

 equator, there must be numerous species which are still unknown to us ; for at present we have only 

 skirted some of its forests, and ascended or descended, as the case may be, a few of its principal rivers. 

 The part of America here alluded to is, if I mistake not, the native country of the beautiful bird figured on 

 the accompanying Plate ; at least it is from thence that most of the specimens I have seen have been 

 procured. My late friend, John Natterer of Vienna, obtained, I believe, several examples on the banks of 

 the Madeira ; and Mr. Bates sent females or young males from the neighbourhood of Ega ; I have also a 

 specimen sent from Ecuador by Mr. Fraser, but said to have been obtained on the Napo. 



In point of affinity, the Clytolcema aurescens is more nearly allied to the C. rubinea than to any other 

 species ; still it differs somewhat both in form and colouring, sufficiently, perhaps, to warrant its being 

 made the type of a new genus ; and, if so, one has already been proposed for it, as will be seen on reference 

 to the synonyms, which are getting pretty numerous as to generic appellations ; I trust, however, that, 

 as I had the pleasure of naming the bird in the first instance, it may be allowed, after nearly twenty years, 

 to remain in the genus in which I have now placed it. 



The male has the chin black ; the throat rich luminous gold-colour ; across the chest a broad band of deep 

 rufous ; on the forehead a longitudinal stripe of rich shining blue ; all the upper surface, two central tail- 

 feathers, upper and under wing-coverts and abdomen bronzy green ; wings purplish brown ; lateral tail- 

 feathers chestnut-brown, tipped both above and beneath with a bronzy lustre ; under tail-coverts deep fawn- 

 colour ; bill black. 



The female or young male of the year differs in having the chin greenish brown, and in the absence of 

 the longitudinal blue stripe on the crown ; the outer feather of the tail chestnut, the three next chestnut 

 with a narrow edging of bronze along their outer margins. 



This latter description probably applies to a young male ; if so, the female is unknown. 



The figures are of the natural size. The plant is the Dichorisandra kucophthalmos.
