SUMMARYSchodde, R., and J. L. McKean. 1973. The species of the genusPorotia(Paradisaeidae) and their relationships. Emu 73: 145–156.The species ofParotiaare reviewed and re-diagnosed, and their distribution and ecology summarized. Five species are recognized. These, in order of their apparent evolutionary relationships, areP. wahnesi, P. helenae, P. sefilata, P. lawesiiandP. carolae.Infra-specific variation inP. lawesiiis assessed, and the racesexhibitsandfusciorreduced to synonymy.P. helenae, conventionally treated also as a race ofP. lawesii, is considered specifically distinct on morphological and distributional grounds; extensions to its previously recorded range in south-eastern New Guinea are given.Differences in the structure of frontal featherings in adult males are the primary morphological characters separating the species. The termssupra-naral tuftsandforehead crestare introduced to define the feather-groups involved. Species-charcteristic combinations of these feather groups are assumed to be correlated with slight but critical differences in displays. Those species in which frontal feathering is simple are considered primitive types, vizP. wahnesiandP. sefilta; those in which it is complex are thought to be derived, vizP. carolae.From correlations between the various combinations of Frontal feathering with the geographical disposition of the species and the recent (Pliocene-Pleistocene) environmental history of New Guinea, some introgressive hybridization between populations and the selection of recombinants may have occurred inParotia and contributed to the evolution of the species.Notes on arena behaviour inP. lawesiiand on requirements for conservation are appended.

SUMMARYHolyoak, D. T. 1973. Comments on taxonomy and relationships in the parrot subfamilies Nestorinae, Loriinae and Platycercinae. Emu 73: 157–176.Relationships and taxonomy in the parrot subfamilies Nestorinae, Loriinae and Platycercinae are reviewed, using published information and museum material. These subfamilies seem to form a monophyletic group. The Neotropical generaForpus, Amoropsitlaca, Psilopsiagon and Bolborhynchusappear to be more closely related to other Neotropical parrots than to any member of this Old World group.Within this group, the Loriinae appear to have arisen from a platycercine-like ancestral stock, with the fig-parrotsPsitlaculirostrisshowing intermediate characters. Because of the marked gap between the fig-parrots and other groups in these characters it is proposed that they be placed in a separate subfamily (Psittaculirostrinae). The Nestorinae may have evolved from an early lory-iike stock.MelopsittacusandPezoporusare probably more closely related to the Platycercinae than to other parrots, andLathamusought probably to be retained in the Loriinae, of which it may be a little-advanced form.Eunymphicusis merged withCyanoramphusbecause of similarities in structure of skull, pattern of plumage, coloration, distribution and calls, Following other recent authors,Barnardiusis kept separate fromPlatycercus.
