One of the very finest Humming-Birds discovered during the last twenty years is the one I have called 

 Heliodowajamla, which inhabits Bogota or its neighbourhood. To this species the bird here represented, 

 which was brought from Ecuador by M. Bourcier, is only second in beauty. Since that gentleman's visit, 

 many other examples have been collected, the greater number of which have found their way into my own 

 cabinet ; but the person by whom and the immediate locality in which they were procured are equally 

 unknown to me. The specimens sent to England by Mr. Eraser during his sojourn in Quito are stated to 

 have been collected at Nanegal. Perhaps, in Popayan or its neighbourhood, the two species jacula and 

 Jamesoni, which are very nearly allied, will be found to inosculate ; at all events, up to this time the former 

 has not been found in Ecuador, nor the latter in Columbia. 



In the naming of this bird after Professor Jameson of Quito, M. Bourcier has my entire acquiescence, 

 since by so doing he will have assisted in perpetuating a name which will ever stand conspicuous among 

 those who have largely contributed to the promotion of natural history. Happily for science, Professor 

 Jameson has long been located at Quito, the capital of one of the richest portions of the New World, 

 both in a zoological and botanical point of view, and few persons have more zealously exerted themselves 

 to make us acquainted with the productions of any country than this gentleman. For myself, I have 

 especial pleasui'c in recording my great obligations to him for the kind and friendly spirit in which he 

 has ever afforded me all the assistance in his power in furtherance of my works on this and two other groups 

 of South American birds. 



The Heliodooca Jamesoni is a larger and more robust bird than the H. jacula, and has on the crown of 

 the head a spear-shaped mark of beautiful glittering green, bounded on each side with jet-black when viewed 

 in front, while in H. jacula the entire crown is glittering green ; the brilliancy of the green crown, as well as 

 that of the under surface, is also less than in that species. The two birds moreover differ in the colouring of 

 their two central tail-feathers, those oi H. jacula being generally of a bronzy hue, while those of H. Jamesoni 

 are as generally black ; the tail, too, of the former is longer and more forked than that of the latter. 



The male has a broad spear-shaped mark of glittering green on the crown, bordered on each side by a 

 mark of velvety black; behind the eye a small spot of white; chin, sides of the neck and breast glittering 

 green, with a patch of shining steel-blue in the centre of the throat; all the upper surface and wing-coverts 

 dark green, washed with bronze at the back of the neck and on the upper tail-coverts ; wings very dark 

 purplish brown ; under surface bronzy green ; tail black, with steel-blue reflexions ; bill black ; feet blackish 

 brown. 



The female has the head and all the upper surface shining bronzy green ; behind the eye a small spot of 

 white ; the under surface creamy white, with a crescent of shining green at the tip of each feather, and a 

 streak of white from the base of the lower mandible ; wings and tail as in the male. 



The Plate represents both sexes about the size of life. The plant is the Tecomafuha.
