I. — Some Additions to the Australian Tertiary Echinoidea. 



By J. Walter Gregory, F.G.S., F.Z.S., 

 of the British Museum (Nat. Hist.). 



(PLATES XIII. and XIV.) 

 rPHE Tertiary Echinoid fauna from the South-east of Australia is 

 1 well known from the work of Duncan, 1 Laube, 2 R. Etheridge, 

 jun., 3 and M'Coy. 4 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 con- 

 siderably 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. 



Dr. J. E. Taylor, during a visit to the cliffs of the Murray River 

 at Morgan, South Australia, made a collection of fossils which is 

 now in the Ipswich Museum. This includes two new species of 

 Echinoids, and a description of these may be conveniently included 

 in the present paper. For the loan of the specimens I must express 

 my thanks to Dr. Taylor.
