_Geographic range._--Micronesia: Caroline Islands--Yap.
_Characters._--Adult male: Resembles adult male of _E. t.
monachum_. Adult female: Resembles adult female of _E. t.
monachum_, but wings and upper parts less buffy and more rufous;
eye-stripe rufous; breast barred on sides only.
_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.
