_Remarks._--No specimen of the Cicada Bird from Yap has been examined by me. For a long time this bird was thought to be a species distinct from any other member of this genus, but Stresemann (1939:126) arranged it as a subspecies of _Edolisoma tenuirostre_. The type specimen is an immature, and the adult is unknown. The presence of rufous coloring shows a relationship with _E. t. insperatum_ of Ponapé, but Mayr, who has examined the type of _E. t. nesiotis_ in the Hamburg Museum, and has obligingly showed me his notes on the bird, says that it has a greater resemblance to the Cicada Bird at Palau especially because of the amount of barring on the underparts. The true status of this bird, as well as that of other members of the avifauna of Yap, will be incompletely known until such time as good collections are available from this island group. =Edolisoma tenuirostre insperatum= (Finsch) Cicada Bird _Volvocivora inseperata_ Finsch, Proc.
