 and Warrnambool, I will again refer to them. At Spring Creek [see Table, p. 288], the upper portion of the series is nearly 100 feet in thickness, consisting chiefly of yellow sandy limestone — the calcareous portion composed almost entirely of polyzoa, and fragments of echini- spines, much comminuted ; but the characteristic fossils of these upper beds are Cellepora gambierensis, Spatangus Forbesii (Hemipatagus Forbesii, Duncan), and the little Terebratula compta. The middle series, which is about 150 feet thick, consists chiefly of soft brown, blue, or yellow sandy clays.

" The prevalence of bivalve shells is very characteristic of these beds ; the most common are Pectunculus laticostatus, and two or three species of Pecten ; while in the beds of the lower series univalve shells predominate. The fossils from the lower beds, Professor M'Coy regards as rather belonging to the Upper Eocene.

" Between Cape Otway and Moonlight Head, only a few patches of Miocene strata occur, showing the enormous denudation to which this coast has been subjected.

" The cliffs at Cape Otway (fig. 2) are occupied by Mesozoic sandstone, overlain by very recent Tertiary calcareous sandstone ; but about a mile and a half west of the Cape, the carbonaceous rocks terminate, and we immediately have a small outcrop of Miocene, which consists of dark slate-coloured stiff clay (g), abounding in fossils, especially two species of Turritella, which may be collected in any quantity. The fossils from here are labelled No. 1. These beds occupy the base of the cliff, and can only be traced for a few chains ; they may be referred to the Lower Miocene series.
