_Remarks._--The Cicada Bird at Palau inhabits the jungles, especially the marginal areas between the thick jungle and the more open woodlands. In 1945, the NAMRU2 party observed only two birds, both of which were obtained. These were found at Peleliu in a small area of undisturbed woodland at the edge of a mangrove swamp. Each bird was perched approximately 25 feet above the ground on the outer branches of a densely foliated tree. The bird is thought not to be so rare as our records indicate; probably its secretive habits conceal it from man except as he makes special search for it. Coultas (field notes) describes the bird as one of the true forest. He found it shy and retiring and possessing a very weak voice. It may be noted that Delacour (1946:2) does not accept the genus _Edolisoma_ but places birds which are currently assigned to it in the genus _Coracina_. =Edolisoma tenuirostre nesiotis= (Hartlaub and Finsch) Cicada Bird _Campephaga nesiotis_ Hartlaub and Finsch, Proc.
