Gould, by whom they were described as above. It is a very 
distinct species, and very rare in collections. Although allied 
to H. exortis, it has too many and too striking differences to 
be confounded with that species.

This well-known species (familiar to ornithologists as H. 
parzudakii) was described by Fraser in February 1840, in 
the ‘ Proceedings’ of the Zoological Society, as Trochilus 
exortis, and by De Longuemare and Parzudaki in the ‘ Revue 
Zoologique, in March of the same year, as Ornismya par- 
zudakii. The name given by Fraser will therefore stand by 
right of priority ; and although one may regret thus to be 
obliged to overturn an old established name, yet in the 
present case the facts are too clear and unanswerable to ad- 
mit the adoption of any other course, and the species must 
hereafter be known as Heliotrypha exortis*. 
It is a beautiful species, very common in the vicinity of 
Bogota, and in collections is generally the sole represen- 
tative of the genus now under consideration. 
I notice that specimens from Hcuador are somewhat larger, 
with longer bill and wings, while the throat-mark is more 
restricted to the centre of the throat than in Columbian birds. 
I do not consider these to be in any way of specific value, 
or even as elevating the specimens to the dubious rank of a 
variety.
