125. (2 specimens.) Shale, with ? plant remains. 
126. Ochreous shaly mudstone, having surface covered with interlacing 
and branching filaments, averaging about 1 mm. in diameter, which may 
be referable to worm-tunnellings or tracks of other burrowing organisms. 
127. Slab of dark shale with surface covered by irregularly-branched 
cylindrical bodies, measuring about 5 mm. in diameter. They are pro¬ 
bably analagous to the fossils found on the surface of the Middle 
Devonian shales of Ilfracombe in the S. W. of England, which have 
been provisionally referred by some authors to sponges. A section of an 
Ilfracombe specimen in my own collection, made many years ago from 
a specimen which I obtained from Sampson’s Cave, shows a more or less 
distinct polygonal meshwork, without, however, any evidence of separate 
spicules, the interstices being filled with fine, angular quartz and felspathic 
mud. A microscopic slide made from the Baw Baw T specimen also shows 
a similar mesh-structure, but more or less broken down by the surrounding 
matrix. 
128. A white quartzose rock with a partially preserved woody stem, 
showing the base of a branch with exogenous structure (silicified). This 
specimen is probably of Tertiarv age. 
From Donnelly’s Ck., Aberfeldy R. Collected by W. Baragwanatfi, 
jun. Nos. 196, 197. 
196. A slab of finely-laminated talcositic shale, with branching and 
radial clusters of dark markings weathered in relief, probably dii£- 
marine burrowing organisms. 
197. A similar rock with a large patch of filamentous and laminar 
graphitic markings. ? Fucoidal. 
From Parish of Moliagul, 2.42 Chains S. from S.E. Corner of 
Allotment A15. Collected by Mr. W. H. Ferguson. Nos. 
198-202. 
The rock containing the fossils is a purple indurated mudstone. The 
fossils are represented by the remains and impressions of a crustacean, 
probably referable to the genus Hymenocaris , and a new species. There 
is little doubt that they are of Lower Ordovician age. 
The specimens are retained, pending the collection of additional 
material for subsequent description. 
From Waanyarra. Collected by W. H. Ferguson. No. 203. 
A branching organism, probably referable to a hydrozoan, like 
Callograptus. 
Other fragmentary fossil remains occur on the same slab, but are 
indeterminable. 
From Specimen Hill, Wedderbuen. Collected by O. A. L. 
Whitelaw. No. 246, Corrected No. (204, old No.). 
A mudstone showing bedding and cleavage; with wrinkled foliaceous 
markings on cleaved surface (? inorganic), and small seed-like bodies 
scattered throughout the mass of the rock, disposed in lines parallel with 
the cleavage, representing crystals of iron pyrites now decomposed to 
limonite.
