Abstract
One of the outstanding features of the Lower Miocene beds in Victoria is the presence of many larger foraminiferal species, many of the genera being restricted to this horizon, thereby being extremely valuable as zonal fossils, and affording excellent markers for the correlation of beds in different areas. The larger foraminifera have been found abundantly in the borings that have been put down for oil and water throughout the State. They also occur in several outcrops. The genera restricted to the Lower Miocene of Victoria include-Lepidocyclina, Cycloclypeus, Trillina, and Hofkerina. These are usually found associated with the more widely ranging large forms as Amphistegina, Operculina, Carpenteria, Gypsina, and Planorbulinella, there being definitely restricted species of the last two genera. These restricted species are found in friable polyzoal limestones and marls, and in hard limestones. In this Bulletin, no attempt is made at systematic descriptions of the foraminifera. It is more in the nature of an attempt to help the field geologist to locate himself in the Tertiary sections throughout Victoria.
