I.—Some Additions to the Australian Tertiary Echinoidea

Abstract

The Tertiary Echinoid fauna from the South-east of Australia is well known from the work of Duncan, Laube, R. Etheridge, jun., and M‘Coy. A collection made by H. P. Woodward, Esq., F.G.S., from the Tertiary beds of Willunga near Adelaide, enables several additions to be made. These are of interest as they considerably strengthen the Cretaceous facies which the fauna owes to the presence of such genera as Holaster and Micraster, and as they throw some additional light upon a genus the stability of which has long been questioned. The collection has been presented to the British Museum (Nat. Hist.) by H. Y. L. Brown, Esq., F.G.S., the Government Geologist for South Australia.
