_Geographic range._--Micronesia: Mariana Islands--Rota.
_Characters._--Adult: Resembles _H. c. teraokai_, but loral spot
larger and more buffy; occiput lightly streaked with white and
white line above eye; top of head and back more oily green and
less blue, darker in female.
Immature: Resembles adult, but underparts and loral spot buffy
with dusky edges; feathers of forehead tipped with buff; remainder
of upper parts slightly darker.
_Measurements._--Measurements are listed in table 33.
_Weights._--The author (1948:64) lists the weights of two adult
females as 84 and 85.
_Specimens examined._--Total number, 11 (4 males, 6 females, 1
unsexed), from Mariana Islands, USNM--Rota (Oct. 18, 19, 22, 26,
Nov. 2).
_Molt._--The 11 specimens taken by the NAMRU2 party at Rota in
October and November are in molt.
_Remarks._--The kingfisher at Rota was taken by Marche in June and July,
1888, and reported by Oustalet (1895:169). It was taken later by the
Japanese and described by Takatsukasa and Yamashina as a new subspecies.
Apparently, no other specimens were taken until the NAMRU party visited
Rota in October and November, 1945, and obtained 11 skins. The bird is
conspicuous and common at Rota.
The color characters of white feathers intermingled with the bluish
coloring of the crown and the occiput and the large, whitish loral spot
place this subspecies as intermediate between _H. c. teraokai_ and the
two subspecies known from the more northern Marianas.
