The detailed lists from the various localities appear in other places in 
these Records, and we are now merely concerned with the results. 
From a couple of miles east of Bealiba eastward to Laanecoorie the 
rocks appear to be entirely of Lanceiieldian age. They have been proved 
on a north and south line along their strike, which is 5 or 10 deg. west * 
of north, for about 15 miles. Doubtless it will be possible when our 
knowledge is greater to subdivide the series; but to do this will require 
better material, and this it does not seem possible at present to obtain, 
and this in spite of the skill and energy with which Mr. Ferguson has 
searched these most unpromising rocks. . There is among the fossils a 
constant repetition of well-known Lancefield forms, and there was nothing 
which seemed to suggest the presence of species not known to occur at 
Lancefield itself. Still, better material may lead to a modification of this 
view. 
About 15 miles north of the east and w 7 est Bendigo-Bealiba line we 
find, at Inglewood, slightly to the east of the Laanecoorie strike, that we 
have the first indication of a change. Two of the three fossils found are 
Lancefieldian, namely, Tetragraptus decipiens and Clonegraptus sp., the 
latter suggesting a Lancefield species. The third fossil, of which there 
were half-a-dozen specimens, was Tetragraptus approximatus. This 
species has hitherto been found only in association with T. fruticosus and 
other Bendigo forms, as near Hustler’s Reef at Bendigo itself, and near 
Dromana. Since the Inglewood find it has been discovered in the Parish 
of Clarendon associated with Clojtograptus rigidus var. tenellus and 
Tetragrapius fruticosus. Undoubted Lancefieldian has been found not 
far to the south-east of the Clarendon locality. 
We have, then, this interesting state of affairs: — T. approximatus is 
found at Inglewood associated with Lancefield forms alone, and at 
Clarendon with the Lancefieldian C. rigidus var. tenellus and the Bendi- 
gonian T. fruticosus, while at Bendigo and near Dromana its associates 
are apparently entirely Bendigonian. Its presence, then, may be taken to 
indicate, on the one hand, the top of the Lancefield, and, on the other, 
the base of the Bendigo, series, and the two series pass into' one another 
without a break. 
We have, then, on the Inglew r ood strike reached the summit of the 
Lancefieldian, and further eastward may expect to find higher rocks as 
we approach Bendigo. South from Inglewood, and on the same strike, 
we find at about 32 miles undoubted Bendigonian at the Loddon Valley 
Gold-fields mine. The species represented are Tetragraptus quadri- 
brachiatus, T. fruticosus , and Clone graptus sp. Still further south, and on 
the same general strike, Campbelltown and Smeaton are also of Bendi¬ 
gonian age. It is, of course, quite possible that higher and lower series 
come in, but so far the only fossils found along this line are Bendigonian. 
The southern extension of the Bealiba-Laanecoorie Lancefieldian belt 
is shown by the finding by Mr. A. M. Howitt, at Wareek, to' the west 
of Maryborough, of a fine series of Lancefieldian fossils. 
At Marong, 8 miles west of Bendigo, and in its immediate neighbour¬ 
hood (Darook, Leichardt), we find undoubted Bendigonian. West of 
Marong a basalt flow hides most of the underlying rock, and possibly 
we may never know its age, but to the eastward, towards Bendigo, there 
is nothing to prevent fossils being searched for and found. We are, how¬ 
ever, not in a state to say whether or not younger beds crop out at the 
surface between Marong and the central Bendigo area.
