"Osmotreron everetti resembles O. axillaris from the Philippines, but
is altogether a larger bird; the purplish chestnut mantle is bordered
above by a very conspicuous interscapulary band of lavender-gray, of
the same color as the crown; this color is of a lighter shade than in
O. axillaris and the interscapulary band is much less distinct and not
so pure gray in the latter. In O. everetti the green of the neck and
breast is a shade lighter and more tinged with yellow, the abdomen
paler and more grayish along the middle. Length, about 279; wing,
161 to 165 ([female] 162 to 165); tail, 91 to 92; bill, 19; tarsus,
23. 'Iris greenish silvery' (Everett); 'iris pearly green; bill red at
base, blue at tip; feet pale slate.' (Guillemard.) I have no female
of true O. axillaris to compare, but the female of O. everetti seems
to be the larger, and the mantle much darker olive." (Rothschild.)
