_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. =Halcyon chloris albicilla= (Dumont) White-headed Kingfisher _Alcedo albicilla_ Dumont, Dict.
