Male.—General color grayish cobalt or smalt-blue; chin, lores, a small 
spot at base of lower mandible, and a narrow frontal line velvety black; 
primaries and secondaries black@@eed with blue; rectrices black below

mouth bright green.” (Whitehead.) Length, about 215; wing, 93; tail, 
100; culmen from base, 23; bill from nostril, 15; tarsus, 17. 
Female.—Similar to the male, but abdomen and crissum whitish. 
Wing, 93; tail, 95; culmen from base, 22; bill from nostril, 14; tarsus, 16. 
Young.—Similar to the adult, but lores and forehead blue; back buffy 
brown; remiges and rectrices largely buffy brown ; under tail-coverts white 
washed with buff. 
“Quite common both in Palawan and the Calamianes. A forest form. 
Four males average: Length, 220; wing, 96; tail, 100; culmen, 25; tar- 
sus, 16; middle toe with claw, 18. Five females, length, 200; wing, 89; 
tail, 89; culmen, 23; tarsus, 16; middle toe with claw, 17. Iris black; 
legs and feet blue; nails black; bill blue, deepest at base, tip sometimes 
black ; eye-wattles blue.” (Bourns and Worcester MS.) 
Genus CALLAEKOPS Grant, 1895. 
“A new genus of Muscicapide most nearly allied to Arses, which it 
resembles in having a disk-like wattle formed by the prolongation of the 
eyelid, which entirely surrounds the rather large eye. As in Terpsiphone, 
there is a large, full, occipital crest, and the tarsi and toes are short and 
slender ; but the tail is like that of Rhipidura, wedge-shaped and composed 
of twelve feathers, the outer pair being two-thirds of the length of the 
middle pair. The first flight-feather is half the length of the second, 
which is about equal to the tenth; the fourth being slightly the longest.” 
(Grant.) 
427. CALLAEOPS PERIOPTHALMICA Grant. 
SHORT-TAILED PARADISE FLYCATCHER. 
Callaeops periopthalmica GRANT, Bull. Brit. Orn. Club (1895), 4, 18; Ibis 
(1895), 253; WHITEHEAD, Ibis (1899), 108; SHARPE, Hand-List (1901), 
3, 263; McGrecor and WorcESTER, Hand-List (1906), 74. 
Luzon (Whitehead). 
“Adult male.—General color deep black with a slight purplish gloss, 
especially on the back and breast; the middle of lower breast and belly 
white, the under tail-coverts being edged with the same color. Wattle 
surrounding the eye, bill, and feet said to be pale blue. Length, 216; 
wing, 89; tail, 114; tarsus, 15. The only specimen sent home by White- 
head was not of his own collecting, but purchased in Manila and, as I 
understand, said to have been obtained in that vicinity. The color of the 
soft parts and sex are, I fancy, only given on the authority of the collector 
from whom the bird was obtained.” (Grant.)
