The endemic species in Borneo are members of four, possibly five, genera
that are also endemic. Four of these five genera are montane in
distribution. The only endemic for which the geographic history cannot
be adequately explained is the monotypic _Pityriasis gymnocephala_. Its
affinities seem to be with the Cracticidae of New Guinea and Australia.
The species has been found throughout Borneo. Since _Pityriasis_ is
endemic to Borneo, it probably was detached from the parent stock at an
early period. The Australasian affinities of _Pityriasis_ emphasize its
zoogeographical peculiarities. A more detailed discussion of this
species appears in the annotated list below.
