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.

Hab. Columbia, Ecuador, Quito ( Jameson ). 
This well-known species (familiar to ornithologists as H . 
parzudatcii) was described by Fraser in February 1840, in 
the f Proceedings 9 of the Zoological Society, as Trochilus 
exortis, and by De Longuemare and Parzudaki in the f 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 Ecuador 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.

is equivalent to publication. But are we all agreed on this point ?— Ed.]
