808 Zoological Society :— 
to the genus Calliphloz, it is one of the most remarkable Humming- 
birds that it has fallen to my lot to describe. In its size and form 
it is very similar to C. amethystina, but in colouring it is like a 
Chlorostilbon. The only specimen I have seen was sent to me by 
T. Reeves, Esq., of Rio de Janeiro. : 
APHANTOCHROA? GULARIS, Gould. 
Crown shining grass-green ; back of the neck, shoulders, back, 
upper tail-coverts, and two centre tail-feathers deep grass-green ; 
under surface of the body grass-green, with the exception of a glit- 
tering patch of lilac on the throat, and the centre of the abdomen, 
the thighs, and under tail-coverts, which are white; primaries pur- 
Jish-brown ; four outer tail-feathers, on each side, purplish-green ; 
bill slightly curved and black, with the exception of the base of the 
under mandible, which appears to have been flesh-colour. 
Total length 47 inches; bill 13; wing 22; tail 13. 
Hab. My specimens were procured on the banks of the Rio Napo. 
Remark.—In the general style of its colouring, and in the short- 
ness and similar colouring of its tail, this bird approaches more nearly 
to Aphantochroa cirrhochloris than to any other species; but it 
differs from that bird in having a much ee bill, and a bright 
metallic deep-lilac patch on the throat, similar to that observed in 
Phaiolaima rubinoides ; and in having white under tail-coverts. In 
size it is somewhat smaller. 
ERIocNEMIs squaMATA, Gould. 
Crown of the head, back of the neck, upper surface, sides of the 
neck, and flanks coppery-bronze, inclining to green on the back and 
to rust-colour on the upper tail-coverts ; throat, chest, and centre of 
the abdomen hoary grey with green and coppery reflexidns ; in cer- 
tain lights the feathers of the throat and chest appear to be edged 
with grey, giving those parts a scaled appearance—hence the specific 
name ; under tail-coverts smoky-grey ; anterior portion of the fea- 
thers clothing the tarsi white, the posterior portion buff; tail dull 
steel-black ; wings purplish-brown ; bill black. 
Total length 4? inches; bill £; wing 23; tail 14. 
Hab. Ecuador. 
Remark.—This bird is nearly allied to Hriocnemis lugens ; but it 
differs from that bird in its considerably larger size, and in the parti- 
colouring of the tarsi-feathers, in which respect it assimilates to #. 
Aurelie. The three species, indeed, viz. HL. lugens, Aurelia, and 
squamata, constitute a minute section of the genus, and all, I be- 
lieve, inhabit very high mountains. 
SCHISTES PERSONATUS, Gould. 
Forehead, face, and throat glittering brilliant green, in the form of 
a mask, posterior to which is a patch of black, below this spring two 
lengthened tufts of violet-blue feathers, below these tufts a cres- 
centic mark of white; crown of the head, back of the neck, back 
and shoulders golden-green ; tail green, each feather crossed near its
