all very regular, but narrowed at the joints ; on the inner toe fifteen, and on 
the outer toe twenty-one. On the hind toe there are five scales. The 
claws are strong, thick, not much arched, rather sharp on the edges, but 
with blunted points, especially on the hind toe. The palate is deeply 
grooved. 
Head and upper part of neck very dark blue, changing according to 
the light into brownish-black on the crown and nape, brighter on the 
cheeks and sides, and passing into dark purplish blue on the lower part of 
the neck; the whole of the back, rump, and upper tail-coverts rich olive- 
green, varied more or less, and particularly on the shoulders, with dull 
verditer green, the feathers shading off into that colour at the tips, the 
general olive hue, however, predominating towards the sides of the body ; 
foreneck, breast, sides of the body, and inner portion of flanks beautiful 
purplish-blue ; the lengthened pectoral plumes which overlap the sides and 
the outer portion of flanks vivid purplish-blue, mixed and varied, especially 
on the former, with verditer green; abdomen, thighs, and vent dull indigo 
or bluish-black, more or less mixed with brown; under tail-coverts pure 
white. The general upper surface of the wings is a rich mixture of blue 
and verditer green, very difficult to express exactly in words, the combina- 
tion having something of the effect, in certain lights, of lapis lazult. 
On a close examination of the larger coverts it is found that they are 
marked transversely with numerous delicate rays of a darker purplish blue, 
adding much to the beauty of the plumage. On the lesser coverts this 
rayed character although present is less conspicuous, and the olive hue 
is more pronounced, while on the scapulars it becomes predominant, 
resembling the plumage of the back. The outer edges of the wings and 
the tertial plumes very rich purplish-blue or obscurely rayed with gree? 
The outer primaries are blue on their outer webs, but this rapidly changes 
to dull sea-green, which colour prevails on both webs of the secondaries, 
only washed with a brighter tint on the outer vane. This colour deepens 
again into olive on the inner secondaries and their coverts, thus harmon” 
ing with the plumage of the back. The under surface of the quills 18 
uniform blackish-brown, and the shafts are white towards the base ; the 
plumes and the larger inner coverts are of the same colour tipped 
on their outer aspect with blue, and the smaller coverts, which are of = 
soft texture, are entirely blue. The tail-feathers are dark olive mixed with 
verditer green on the upper surface and changing to dull olive-brow®: with 
lighter shafts, on their under surface. 
The bill has lost its original colour through being dried. On the frontal 
plate and along the basal edges of both mandibles it appears to have been 
dark red, fading outwards. The culmen still has traces of its original pinkY
