Malindangia mcgregori Mearns, Phil. Journ. Sci. (1907), 2,
sec. A, 355.
Mindanao (Mearns).
"Adult male and female.--Upper parts including crown, mantle, rump,
upper tail-coverts, and middle pair of tail-feathers uniform light
gray; forehead, chin, throat, breast, and sides of head to above eyes
black; innermost secondaries, scapulars, and least wing-coverts gray
like the back; middle and greater wing-coverts and a broad external
band on innermost pair of secondaries white; remaining wing-quills
black externally, broadly white on inner webs at base; alula all
black; axillars and under wing-coverts white; three outer rectrices
tipped with grayish white on both webs, the innermost of the three
narrowly, the next broadly, and the outermost for more than one-third
of its length; chest, flanks, and thighs gray like the back, this
color fading to whitish on the abdomen and becoming pure white on
the under tail-coverts. Iris red or reddish brown; bill all black;
feet plumbeous-black, with under side of toes yellow. Three adult
males measure: Length, 236 to 240; alar expanse, 335 to 342; wing,
110 to 113; tail, 108 to 117; culmen, 19 to 19.5; tarsus, 23 to 24;
middle toe with claw, 20 to 21. Female: Length, 230; alar expanse, 330;
wing, 108; tail, 111; culmen, 19; tarsus, 23; middle toe with claw, 21.
"Remarks.--The black of the under side of the head extends around the
neck and forms an incomplete black neck-collar which in the oldest
males is but narrowly interrupted in the median line above. The sexes
are colored alike, but one female (No. 14,177), probably immature,
has the black areas of the head and neck replaced by a dark gray
color. The plumage otherwise differs from that of the adult only
in having scarcely discernible fulvous edgings and wavy cross-bands
to the feathers of the abdomen. This species was abundant on Mount
Malindang. Fifteen specimens were collected, ten of them males and
five females." (Mearns.)
Genus EDOLISOMA Jacquinot and Pucheran, 1853.
This genus is similar to Artamides, but its members are smaller and
the bill is decidedly more slender. The plumage is unbarred in the
adult and the male has the chin, throat, forehead, and face masked in
black, or else the whole plumage is black. The young have the under
parts barred. The following key to species is modified from the one
given by Grant, Ibis (1896), 538.
