N0.125S. COLLECTION OF HUMMINGBIRDS— OBERIIOLSER. 321 
liroAvn terminal band on the tail and the metallic green auricular.s; 
but in other respects it seems to agree with the type. 
This ])ir(l exactly resembles the only other specimen known, which is in the 
British 3Iuseum collection, antl which Gould considered a distinct species and named 
after its collector. Our specimen was shot in the Chillo \'alley near Quito, and was 
feeding on the aloe flowers in company with P(itagon(( gl(j(ts. 
There appear to be absolutely no structural differences to sepai'ate 
this species genericalh', and Mr. Hartert has very properly placed it 
in the genus Collhrl {^^ Pctasophora)^ . Indeed, there arc not lacking 
indications that it ma}' prove eventually to lie but a peculiar color phase 
of Colihn ioJatus {— Petasoj)hora iolata)^ corresponding to that of the 
specimen of Ocreatus nidanantheras described hereafter. 
ANTHRACOTHORAX VIOLICAUDUS IRIDESCENS (Gould). 
Lampomi^ iridescens Gould, Introd. Troch., 1861, p. 65. 
Six .specimens from the vicinity of Nanegal, Ecuador. These are 
subspecitically distinguishable from true m'olicaudus of northeastern 
South America, and should bear the name above given. They differ 
from the tj^pical form by reason of a decided bluish tinge on throat 
and breast, and also in the usually longer bill. 
Confined to the western side, and I believe we obtained all our specimens in the 
banana plantations at Nanegal, where I frequently saw them hovering among the 
ragged leaves hanging down the trunks of the banana trees. Local name, "Plata- 
neros negros." 
TOPAZA PELLA PAMPREPTA, new subspecies. 
Three adult males, all from Suno, on the Rio Napo, east Ecuador. 
These extend the range of the species a long distance to the westward, 
and add it to the fauna of Ecuador. They differ from typical Tojxiza 
pella from British Guiana in the very much greater length of the long 
tail feathers and in the somewhat shorter wing. There appears to 
be absoluteh' no constant difference in color, but the discrepancy in 
size is so marked that it seems advisable to recognize the Ecuador 
bird in nomenclature. It may be described as follows: 
7//7>c.— Male, adult, No. 174294, U. S. N. M.; Suno, Rio Napo, 
Ecuador, May, 1899; Goodfellow and Hamilton. Top and sides of 
head velvety purplish black; cervix and sides of neck rich metallic 
maroon purple; back shining reddish orange, shading posteriorly into 
the bright metallic green of the upper tail-coverts; wings fuscus with 
a purplish gloss, the innermost secondaries chestnut, the superior 
coverts like the back; tail chestnut, the two middle pairs metallic 
green, the succeeding pair much elongated, purplish black; throat 
glittering greenish ^^ellow; jugular band purplish black, continuous
