Two species of Delepinea from New South Wales
£1.00
The Visean species Chonetes aspinosa Dun is re-described and is shown to be a typical representative of the genus Delepinea Muir-Wood. A row of cardinal spines is present and it is argued that such spines were normally present on all species of the genus. Details of the internal structure of both valves are given. A new species, D. gloucesterensis, is described from rocks of Middle-Upper Visean age.
