Genus eRe AG Sees Gray, 1840. 
This genus resembles Osmotreron, but it has a longer and more strongly 
graduated tail and the hard portion of the upper mandible is shorter. 
12. SPHENOCERCUS AUSTRALIS McGregor. 
SOUTHERN WEDGE-TAILED PIGEON. 
Sphenocercus formose McGrecor, Bull. Philippine Mus. (1904), 4, 9; Mc-

Batan (McGregor) ; Calayan (McGregor) ; Camiguin N. (McGregor). 
Adult male.—General color above olive-green, lighter and grayish on 
neck and sides of neck; crown ochraceous-buff ; lower parts uniform green 
from chin to abdomen; middle of abdomen white, washed with pale 
yellow; sides blue-gray; flanks and thighs dark olive-green, mixed with 
fine lines of pale yellow; under tail-coverts pale yellowish (the longest 
buffy), each with a wide, dark olive-green shaft-mark ; shoulders maroon 
connected by a maroon band across the back; primaries and secondaries 
black; secondaries and greater coverts with narrow margins of pale. 
yellow ; inner secondaries and tail dark green like back; tail black below 
with a narrow gray tip. Bill ight blue, the tip whitish; skin about eye 
blue; inner ring of eye clear blue, outer ring pink, a dusky intermediate 
ring; legs dull carmine, nails pale blue. Length, about 355; three 
specimens measure: Wing, 188 to 197; tail, 125 to 130; exposed culmen, 
19 to 20; tarsus, 24 to 27; middle toe with claw, 38 to 40. 
Adult female—Differs from the male in-lacking the ochraceous of 
crown and the maroon of shoulders and back, the entire upper parts being 
green. Three specimens measure: Wing, 185 to 189; tail, 118 to 125; 
culmen, 19 to 19.5; tarsus, 24 to 27; middle toe with claw, 35.5 to 37.5. 
This species is, closely related to Sphenocercus formose and specimens 
of the two species should be compared. It is not uncommon in Calayan 
and Camiguin. We were first led to search for it by hearing its weird, 
prolonged cry which is remarkably like that of a child in pain. Having 
located the tree in which one of these birds was resting it was difficult 
to see the bird as its yellowish green under parts were in perfect harmony 
with the color of the leafy branches. 
Genus OSMOTRERON Bonaparte, 1854. 
Length, 280 to 305 mm.; colors largely yellow or olive-green ; primaries 
black; secondaries and coverts with conspicuous yellow borders;> tail
