VI TROCHILIDAE ay 
Colombia, the “ Warrior” or “ Helmet-crest,” is dark green, with 
blackish sides to the head, a black and white crest, a green and 
white chin margined with black, a white beard, a greyish abdo- 
men, and purplish and white lateral rectrices. The female lacks 
the elongated feathers, and has white under parts spotted with 
dusky. Rhamphomicron heteropogon of Colombia, one of the 
sharp-beaked “ Thornbills,” is greenish-bronze, with browner tail 
and abdomen, and a long amethystine beard surrounded by 
bronzy-black. . microrhynchum, having rich purple upper 
parts and a lustrous green throat, extends to Ecuador, while 
other members of the genus range to Bolivia. The hens are 
comparatively dull. Opisthoprora euryptera of Colombia, which 
is bronzy-green with a little rufous and white below, has an 
upeurved bill, like <Avocettula.  Patagona gigas, the largest 
Humming-bird known, inhabits the Andes from Ecuador to Chili ; 
it 1s greenish-brown, with white rump and rufous under parts. In 
Aglaeactis, of the Andes from Colombia to Bolivia, the coloration 
is brown, dark buff, or black, with glittering amethystine or 
green lower back, and a white or buff pectoral tuft. The chief 
marvel of the Family is, however, Loddigesia mirabilis, originally 
found in Northern Peru by a botanist named Matthews, and re- 
discovered by M. Stolzmann! in almost the same locality. It is 
shining bronzy-green, with whitish under parts surrounding a 
black central area; the head and its crest are lustrous cobalt-blue, 
the throat is emerald-green with black margin, the metatarsi are 
covered with white feathers. The two lateral rectrices are extra- 
‘ordinarily prolonged, and resemble black wires with large steel- 
blue terminal discs; the shafts normally cross each other at their 
bases and again near their tips, but the discs are frequently brought 
together in flight, or extended horizontally, if not turned above the 
head. The median tail-feathers are much reduced. The female 
is green, varied with white below; the external pair of steel-blue 
lateral rectrices shewing small spatules.  Cephalolepis delalandi, 
of South-East Brazil, is bronzy-green above, and fine violet-blue 
bordered with grey below, while the long ghttering green crest 
terminates in a single black plume. The crestless hen is grey 
below. rioenemis, of the Andes from Colombia and Venezuela 
to Bolivia, shares with Panoplites and the spatulate-tailed 
Spathura of the same regions the characteristic of possessing
