THE accompanying description applies to a most beautiful 
bird which has been submitted to the British Museum by 
Mr. Charles Hose, who procured it on Mount Dulit. It is a 
larger bird than C. virddis, but inferior in size to OC. White- 
headi, and differs from both in its bright blue breast. 
I propose to call it, after its discoverer, 
Calyptomena Hlosit, sp. n. 
Adult male——General colour emerald-green, with a black 
spot on the forehead, nearly concealed by the loral plumes 
which overhang the bill, the lateral frontal plumes having 
concealed black bases; on the occiput a spot of velvety 
black, and a small spot of black on each side behind 
the ear-coverts; on the Jower hind neck another patch 
ot velvety black ; on ali the median and greater wing-coverts 
a rounded subterminal spot of black; quills black, externally 
emerald-green ;_ the innermost secondaries entirely green 5 
upper tail-coverts very long, green like the back, and entirely 
concealing a lateral patch of brilliant cobalt-blue feathers ; 
tail-feathers green, with black shafts, with a broad terminal 
band ef black ; throat and entire sides of body emerald-green, 
the centre of the body bright cobalt-blue from the lower 
throat downwards; under ae coverts blue, with greenish 
bases; under wing-coverts dark emerald- ereen, and quills 
black below. 
Total length 8°5 inches, culmen about 0°8, wing 5:2, tail 
2°4, tarsus 1:0. 
Adult female.—Dhitiers from the male in being much duller 
in colour, more yellowish-green in tint, especially on the 
under surface, where the lower breast, abdomen, and under 
tail-coverts are pale blue, not rich cobalt as in the male. 
The black spots on the forehead, occiput, hind neck, and 
behind the ear-coverts are entirely wanting, and on the wing- 
coverts the black spots are contined to the median series 
only; the tail-feathers are entirely dark green, blackish near 
the base.
