_Geographic range._--Micronesia: Mariana Islands--Guam, Rota,
Tinian, Saipan.
_Characters._--Adult male: A green dove with crown, forehead,
anterior lores, and spot at base of mandible near "aster purple,"
margined with pale yellow especially on top of head; chin and
throat pale yellow to white; sides of head greenish-gray, darker
on occiput; breast green with pearly-gray tinge on feathers of
middle part; lower breast with dark purple patch; abdomen orange
with yellowish-green coloring at midline; anal region and lower
tail-coverts yellow, tinged with orange on lower tail-coverts;
sides and tibia greenish with yellow tinges; upper parts green,
more yellowish-green on rump; wings glossy, upper wing-coverts
brighter in middle and margined with yellow; under side of wing
and under side of tail gray; upper side of tail green with broad
grayish terminal band margined with yellow; iris pale yellow; bill
grass-green; legs and feet reddish-black.
Adult female: Resembles male, but slightly smaller with neck
greener. Immature resembles adult, but lacking colored crown; body
feathers edged with yellow.
Birds from Guam, Rota, and Tinian exhibit no conspicuous
differences. _P. roseicapillus_ is closest to _P. regina_ of
southern Papua, Lesser Sunda Islands, and Australia being,
according to Ripley and Birckhead (1942:3), "Similar to _regina_,
but crown and abdominal band darker; malar apex concolorous with
crown; hind neck more grayish; tail-bar wider and paler."
_Measurements._--Measurements of _P. roseicapillus_ are presented
in table 26.
_Weights._--In 1948 (1948:59) I listed the weights of 14 adult
males as 81-103 (90), of 4 adult females as 85-99 (92), and of one
nestling in post natal molt as 44 grams. These were taken at Guam.
_Specimens examined._--Total number, 43 (32 males, 10 females, 1
unsexed), as follows: Mariana Islands, USNM--Guam, 28 (March 8,
May 25, 27, June 3, 12, 14, July 2, 6, 10, 18, 19, 29, Aug.
21)--Rota, 3 (Oct. 28, 31, Nov. 2)--Tinian, 1 (Oct. 26);
AMNH--Guam, 8 (Aug.)--Tinian, 3 (Sept.).
