V PHASIANIDAE ids 
the tail is vaulted, the cheeks exhibit patches of rugose blue 
skin—red in L. diardi—while the male has a pair of spurs and 
an erect crest with bare-shafted plumes. Z. nobilis of Borneo is 
purplish-blue with fiery chestnut rump-region, golden lower 
breast, black head, throat, and wings, the four median rectrices 
being entirely buff and the lateral black with buff markings; JZ. 
viellot. of Siam, the Malay Peninsula, and Sumatra has the 
lower breast black, and the two middle rectrices white, Z. ignita 
of China differmg in its chestnut-spotted flanks ; LZ. diardi (prae- 
lata) of Siam, Cambodia, and Cochin China has a grey and 
black mantle, neck, and breast, a golden buff lower back, and 
crimson-tipped rump-feathers. The females have the mantle red- 
brown or chestnut, and outer rectrices of the latter colour in JL. 
vieilloti, but black in L. nobilis ; in L. diardi the black wing-coverts 
have wide buff bars. This sex of L. ignita seems to be unknown. 
Acomus has naked cheeks, but no crest or wattles ; the tail is vaulted, 
and a pair of spurs is found in both sexes. A. erythrophthalmus 
of the southern Malay Peninsula and Sumatra is chiefly purplsh- 
or bluish-black with fiery golden lower back, rich buff tail, and white 
wing-markings ; A. pyronotus of Borneo exhibits white shaft- 
stripes on the breast; 4. cnornatus of West Sumatra, of which 
the male only has been discovered, has black plumage margined 
with dark blue-green, therein somewhat resembling the hens of 
its congeners, which are black glossed with purplish-blue. In 
habits this genus apparently resembles Lophura. 
Lophophorus contains four gorgeous species of almost unsur- 
passable brilliancy, among which the Monal, constantly misnamed 
the Impeyan Pheasant, is best known. The tail is rounded, each 
metatarsus is provided with a spur in the male, and bare blue 
skin surrounds the eye. The Himalayan Monal (LZ. refulgens) 
has a crest like that of the Peacock, uniform in colour with the 
purplish-green head; the neck is purple, coppery, and green, the 
mantle golden-green, the lower back white, and the tail chest- 
nut; the wing- and tail-coverts being green or purple with blue 
and green reflexions, the under parts black, and the remiges 
dusky. Its habits differ somewhat from those of other Pheasants, 
a preference being shown for grassy hill-forests not far from the 
snow-line; it roosts in trees, though generally found on the 
ground during the day, and is not very wild, trusting to its speed 
of foot in open spots, but readily taking to wing in the wood-
