(syn. Philemon Ϯ Silver-crowned Friarbird P. argenticeps) Portmanteau of specific name Tropidorhynchus argenticeps Gould, 1839, and genus Philemon Vieillot, 1816, friarbird; "In my "Reference List" in 1912 I classed all the species under Philemon, but in my 1913 "List" I allowed four groups, placing argenticeps under Philemon, buceroides under Neophilemon, corniculatus under Tropidrhynchus [sic], and citreogularis (as orientalis) under Microphilemon. The consideration of the whole series for the purposes of this work shows that argenticeps and "buceroides" (auct.) are closely allied but are easily separable from Philemon, and I reject Philemon from the Australian List placing the two together, but as the name Neophilemon may be questioned I propose Argentiphilemon for Tropidorhynchus argenticeps Gould."
