Abstract:Summary The taxonomic relationships of two Bornean endemics, Pityriasis gymnocephala and Chlamydochaera jefferyi , have been considered to be uncertain. DNA-DNA hybridization was used to compare the single-copy sequences of each of these two species with other passerine taxa. The DNA data support other evidence indicating that Pityriasis is a cracticine corvoid, most closely related to the Australo-Papuan genera Cracticus, Gymnorhina, Strepera , and Peltops. Chlamydochaera is a typical turdine thrush, closely related to Turdus . This supports and confirms the morphological evidence presented byAmes (1975). Chlamydochaera is not related to the cuckoo-shrikes ( Campephaga , etc.) of the Tribe Oriolini.
