1. Description or A New Species or Hummine Birp, 
FROM Quiyos. By Joun Gou.p, F.R.S. erc. 
Mr. Gould exhibited a Humming Bird, lately received from Quijos, 
which is very nearly allied to Threnetes leucurus, but which differs 
from that species in its larger size, and in having those parts of the 
tail-feathers of a deep fawn-coloured hue which are white in 7’. lew- 
curus; precisely, in fact, the difference which occurs between La- 
fresnaya flavicaudata and L. Gayi. For this bird Mr. Gould pro- 
posed the name of 
THRENETES CERVINICAUDA. 
Head, all the upper surface, upper wing-coverts, two central tail- 
feathers, sides of the neck, breast and flanks shining olive-green ; 
wings purplish-brown ; lateral tail-feathers deep fawn-colour, stained 
on the apical half of the outer margin and the tip of the outer feather 
with dark brown; a crescent of the same, but of a much paler hue, 
at the tip of the next; a still fainter mark of the same colour near 
the tip of the external web of the third; and a nearly obsolete mark, 
of a similar tint, in the same situation on the fourth; lores and ear- 
coverts brown; on the chin and throat a lengthened triangular mark 
of black, bounded on either side by a narrow line of greyish-white, 
and below by a broad band of deep sandy-buff crossing the throat ; 
centre of the abdomen greyish-buff ; under tail-coverts olive, narrowly 
edged with greyish-buff; bill black, with the cutting edge of the 
upper mandible and the basal three-fourths of the under one pearly- 
white ; feet yellow. 
Total length, 4% inches; bill, 1,4; wing, 23; tail, 1}. 
Hab. Quijos, in Ecuador. 
2. List or A CotLectiIon or Birps RECEIVED BY Mr. Govu_p, 
FROM THE PROVINCE OF Qu1sJ0S IN THE REPUBLIC OF 
Ecuapor. By Puainie Luriey Scuater, M.A. 
(Aves, Pl. LXVI. and LXVII.) 
Among the many novelties in ornithology lately received by 
Mr. Gould from different parts of the world, is a small but valuable 
collection of birds from the province of Quixos, or Quijos, in the 
republic of Ecuador. This country, which lies on the eastern slope of 
the Andes, where the Rio Napo and other adjoining tributaries of the 
mighty Amazon take their rise, is a very interesting locality to those 
who study South American ornithology, being intermediate between
