3. Topopsis GRAYI. 
Beneath bluish white, almost white on the throat; head light- 
greenish blue, the centre of the crown dusky ; a black spot on the 
ear-coverts extending towards the nape; back dusky, the feathers 
margined with greenish blue; wings dusky, the quills margined 
with rufous olive, shoulder-coverts margined with greenish blue ; tail 
dusky olive, with a minute whitish spot at the tips of the feathers ; 
thighs rufous-tipped. Bill black; feet dusky. 
Total length 53 in.; wing 23 in.; bill from gape ;§, in. 
The bill in this species is nearly as broad as in Macherirhynchus. 
I have named this interesting bird after Mr. George Robert Gray, 
who has described the other species of this genus sent home by me. 
Hab. N.W. peninsula of New Guinea: Mountains of Sorong. 
4. GRACULA PECTORALIS. (Pl. XX.) 
Black, the feathers broadly margined with metallic green and 
purple; plumes of the neck and breast decomposed, and of a rich 
orange-buff colour, as are also the vent, rump, and upper tail-coverts ; 
on the nape a collar of whitish buff reaching round to the orange of 
the throat ; under tail-coverts cream-white, tinged with orange at 
the base; a white band across the wings towards the tips. Iris 
yellow ; bill and feet Bale, yellow. 
Total length 10 in. ; wing 53 in. 
The young bird has the breast and belly black, eee mar- 
gined with light orange. 
This species differs from the rest of the genus in having neither 
wattles nor naked skin on the face, but in general structure and co- 
loration closely resembles the other species. 
Hab. N.W. peninsula of New Guinea: Sorong. 
5. PrrLonopus HUMERALIS. (Pl. XXI.) 
Very near P. iozonus, G. R. Gray, but a little larger, and at once 
distinguished by the violet-grey patch on the shoulder haying its 
lower half deep purple; the tail also wants the grey apical band of 
that species, which is replaced by a subapical narrow one, only visi- 
ble on the lateral feathers and beneath. The wing-coverts are all of 
a rich violet grey, margined with green. Chin ashy; the rest as in 
P.iozonus. Bill greenish, tipped with bright yellow, base above red 
and swollen; feet purple red. 
Total length 8? in.; wing 47 in. 
Hab. Salwatty, and the adjacent coast of New Guinea.
