From Winter’s Freehold, No. 1 Mine, Sebastopol.—Nos. 4170-4172. 
Phyllopod Crustacea. —4170. 
Sponge spicules, long and straight.—4171( ?), 4i72(?). 
Of the specimens from the remaining localities, Nos. 4173-4175 are 
phyllopod Crustacea, while the rest are indeterminate. 
These 61 specimens from the Ballarat district are what I picked out 
from a large collection made by Mr. Ferguson, in the hope that on closer 
examination they would afford some reliable data for determining the age 
of the rocks. I think from the Phyllopods, which appear to resemble 
those of known Ordovician age from elsewhere in Victoria, that the horizon 
is probably Lower Ordovician, but do not care to go further.

From the most southern corner of Allot. 19B, of Section n, parish of 
Clarendon, N. 35 deg. W. 4 chains.—Nos. 4357-4411.—Collected 
by Mr. W. FT Ferguson. 
Clonograptus rigidus var. tenellus .—4359. 
Bryograptns sp.—4376, 4408. 
Tetragraptus decipiens.—\$&, 4366, 4372, 4377, 4393, 4394, 4397, 
4411. 
Tetragraptus fruticosus. —4382, 4387. 
Tetragraptus approximate. —4360 (?), 4373( F), 4380, 4389. 
Tetragraptus sp., juv.—4370, 4398. 
Didymograptus sp.—4391. 
There is a very large number of Phyllopods present on the slabs, which 
may repay further investigation. 
This collection is of some importance, as we have associated for the 
first time Clonograptus rigidus var. tenellus and Tetragraptus fruticosus , 
the one characteristic of Lancefieldian, and the other of Bendigonian. 
Tetragraptus approximatus is associated with Lancefieldian forms at Ingle¬ 
wood, and with Bendigonian at Hustler’s Reef, Bendigo, and near 
Dromana. We are then, at these places, apparently on the border line of 
the two great subdivisions, which form a continuous series.
