'Portion of a long poem printed in four numbers of the Melbourne Review, 1883.' Notes on the Poems (p.335)
Textual differences and the note on the extract on page 335 of the Australasian Anthology source indicate that this extract is from the 1883 version of the poem published in nine parts in the Melbourne Review, January, April, July and October 1883. See Carol Mills and June Dietrich, Melbourne Review Index 1876-1885 (1992): 9-10. The 1883 version is not yet indexed on AustLit.
