178 A MANUAL OF THE BIRDS OF AUSTRALIA. 
Small Lapwings without spurs or wattles, proportionately long bills, long 
wings, short tail, long legs and feet. The bill is straight, as long as the head, with 
a distinct swollen dertrum ; nostrils short and linear, situated near the base of the 
bill in a groove which extends over two-thirds the length of the bill. Wings long 
with the first primary longest. There is a bony knob at the bend of the wing in 
place of a spur. Metatarsus long and slender, apparently scutellated before and 
behind with a narrow row of hexagonal scales on each side ; middle toe more than 
half the length of the metatarsus ; distinct hind-toe and claw. Toes only slightly 
connected at the base. This genus is monotypic and confined to Australia.

DisTRIBUTION.—Australia generally. Not Tasmania. 
Adult male——Head, sides of face, hind-neck, upper mantle, and a broad band 
across the breast black ; back and wings olive-brown like the middle of the rump, 
upper tail-coverts, and middle tail-feathers ; a portion of the outer edge of the wing, 
white ; primary-coverts and primary-quills brown, the latter paler on the inner 
webs and becoming white at the base, the inner primaries white at the tips and 
fringed with white on the inner webs ; secondaries dark brown at base with broad 
white tips, the long innermost secondaries like the back ; outer tail-feathers white, 
the outermost pair edged with olive-brown on the outer web near the tip; throat 
and fore-neck white like the lower sides of neck, abdomen, and axillaries ; the 
long feathers on the sides of the body chestnut, edged and tipped with white ; some 
of the feathers adjoining the pectoral band black, edged with white on the outer 
web ; flanks, sides of rump, and under tail-coverts white, with dark centres to 
the feathers at the tip, more or less mixed with chestnut ; inner under wing-coverts 
white, the long ones with a brown spot at the tip, the marginal coverts blackish ; 
bill, culmen, and distal third black, remainder red ; iris brown; feet and tarsi 
blue ; knees and tibia red. Total length 174 mm.; culmen 22, wing 108, tail 46, 
tarsus 41. 
Adult female.—Similar to the adult male but has the crown of the head brown. 
Young— General colour of the upper-parts earth-brown, including the head, 
back, wings, and middle tail-feathers, with pale edges to the upper wing-coverts, 
the dark and light patterns on the wing similar to the adult; throat and general 
under-surface white, including the middle of the breast, with a slight indication of 
the black pectoral band on the sides of the latter, and the chestnut flank feathers 
appearing. 
Another immature example, rather more advanced in age, has the upper 
wing-coverts uniform without any pale edges, the cheeks, ear-coverts, and a band 
on the hind-neck inclining to black, the pectoral band more pronounced on the sides 
of the breast and faintly indicated across the middle of the latter, the chestnut 
on the sides of the body well marked, under wing-coverts for the most part white. 
A further specimen shows a still greater advance, in having the pectoral band 
complete in form but brown in colour, with a few white feathers intermixed, the 
dusky-brown on the top of the head still retained, the black on the under wing- 
coverts increased as also the black on the sides of the breast.
