NUTMEG PIGEON, 269 
which is the longest, the remainder gradually decreasing ; the secondaries very short. 
The tail is ermaginate, the feathers fourteen in number, truncate at tip, and is only 
about half the length of the wing; upper tail-coverts short, under a little longer, 
a little more than half the length of the tail. The legs are very stout, the tarsus 
about as long as culmen, only feathered on upper half of the front, the lower half 
showing a few large scutes, the hind portion being covered with minute reticulation. 
The toes are long and stout, formed as in Globicera, but much longer. 
Coloration pure white, primaries, secondaries and apical portion of tail slaty- 
black, sometimes a few blackish spots on under tail-coverts, flanks, etc.

DistrisutTion.—Northern New South Wales, Queensland, Northern Territory, North-west 
Australia. 
Adult male-—General colour white ; bastard-wing and primary-coverts black ; 
primary- and secondary-quills black, everywhere dusted with grey ; tail white, 
broadly tipped with black, more narrowly on the outer feathers, the outermost 
margined with black down to the base ; the feathers of the lower-abdomen, flanks 
and under tail-coverts with submarginal black spots; quills below lead-grey ; 
bill yellow, black at the base ; iris brown, feet slate colour, Total length 345 mm. ; 
culmen 26, wing 225, tail 120, tarsus 27. 
Adult female-—Similar to the male. 
Nest.—Flat, straight, being merely a few sticks or twigs placed crosswise— 
some are more substantial, being built of green branchlets ; usually situated on a 
horizontal branch of any tree, not unfrequently in mangroves overhanging water, 
and occasionally near the ground or on rocks. Sometimes three or four nests are 
situated in one tree, 
Eggs.—Clutch, one; smooth and glossy; pure white. Measurements of two 
eggs, axis 4446 mm., diameter 30 mm. 
Breeding-season— November to January. 
Distribution and forms.—Throughout the Moluccas, New Guinea and outlying 
islands, migrating into tropical northern Australia and on the east coast reaching 
into New South Wales. Subspecies are not easily differentiated on account of almost 
pure white coloration, the Australian form WM. 6. spilorrhoa (Gray) being recognised 
by means of the black spotting on the under tail-coverts, this feature being more 
or less absent in the typical race. 
Genus GLOBICERA. 
Globicera Bonaparte, Comptes Rendus Acad. Sci. Paris, Vol. XXXIX., p. 1072, (about Dec. 
llth) 1854. Type (by tautonymy): Columba globicera Wagl. = Columba pacifica Gmelin. 
Large Fruit Pigeons with stout bills bearing a basal globular excrescence, long 
pointed wings, long tails, small stout legs and feet. The bill is rather long for this 
group, the dertrum stout, about half the length of the bill, the culmen basally bearing 
a large excrescence (said to be globular in the living bird) truncate by the frontal 
feathers and showing the nasal apertures as somewhat rounded holes in the anterior 
portion ; the lower mandible rather strong, the rami a little curved, the interramal
