Camiguin N. (McGregor); Mindanao (Celestino); Samar (Steere Exp.,

Bourns & Worcester, Whitehead.)

Adult male.--General color light azure-blue; rump and upper

tail-coverts lighter; breast darker; frontal line, chin, lores,

and a narrow circumocular line velvety black, forming a mask which

is narrowly bordered behind with bright silvery cobalt-blue, widest

behind forehead and chin; middle of lower breast, abdomen, under

tail-coverts, wing-lining, and axillars white; wings and tail black,

the exposed edges of feathers dark azure-blue, except first and second

primaries; two outermost pairs of rectrices narrowly tipped with

white in old birds only. Iris brown; the narrow eyelids light blue;

bill blue, except edges and tip which are black; legs and feet blue;

nails blackish. Length, 154; wing, 67.5; tail, 67; culmen from base,

15; bill from nostril, 9; tarsus, 16. In the slightly immature, but

fully feathered, male the crest is less developed, the feathers of

the crown are less scale-like, and the upper parts are darker blue

than in the fully adult male.

Adult female.--General color dull verditer-blue; head, neck, and

sides of head brighter; forehead dull cobalt; chin whitish, bordered

by dull cobalt; throat, breast, and sides grayish, washed with dull

azure-blue, shafts white; abdomen, flanks, under tail-coverts, and

middle of lower breast white; wings and tail blackish brown, edged

with dull verditer-blue. Wing, 64; tail, 64; culmen from base, 14;

bill from nostril, 9; tarsus, 17.

Young in first plumage.--Above smoky gray; below white; a dusky

band across fore breast; wings and tail blackish brown; primaries

and secondaries edged with verditer; outer webs of rectrices washed

with verditer.

"Rare in Samar. Always found in company with other flycatchers. Four

males average: Length, 137; wing, 63; tail, 62; culmen, 13; tarsus,

14; middle toe with claw, 13. A female, length, 130; wing, 59; tail,

55; culmen, 13; tarsus, 14; middle toe with claw, 13. Iris nearly

black; legs and feet slaty blue; nails usually black, in one case

bluish slate; bill blue, with black tip; eye-wattles blue. Breeding

in August." (Bourns and Worcester MS.)

The specimens from Camiguin Island, north of Luzon, on which was based

Camiguinia personata, are slightly larger than specimens from Mindanao

and the latter are probably Cyanomyias helenæ of Steere. There appears

to be no ground for retaining C. personata.

Genus CYANOMYIAS Sharpe, 1879.

Bill slightly compressed near tip, depth at nostril two-thirds

of width, outline sightly concave toward the tip; rictal bristles

conspicuous, the longest more than bill from nostril; wing and tail

about equal, wing formula as in Hypothymis; tarsus one and one-half

times the bill from nostril; feathers of head stiffish, decomposed

basally and conspicuously antrorse on lores; feathers of occipital

crest long and narrow.
