Turritella circumligata, Verco This mollusc is still living on the coast 
of South Australia, and has been 
dredged at 110 fathoms. In the 
present bore it probably occurs near 
the summit of the Janjukian. 
The series of ostracoda here determined and described contains a 
large percentage of forms still living. Of the Janjukian species 
persisting into modern times are— 
Argillcecia badia, G. S. Brady. 
Macrocypris decora, G. S. Brady sp. 
„ tumida, G. S. B. 
Bairdia amygdaloides, G. S. B. 
,, australis, Chapm. 
Cythere canaliculata, Beuss sp. 
crispata, G. S. B. 
dasyderma, G. S. B. 
dictyon, G. S. B. 
lactea, G. S. B. 
lepralioides, G. S. B. 
lubhockiana, G. S. B. 
militaris, G. S. B. sp. 
normani, G. S. B. 
obtusalata, G. S. B.

rastromarginata, G. S. B. 
scabrocuneata, G. S. B. 
scintillulata, G. S. B. 
scutigera, G. S. B. 
wyville-thomsoni, G. S. B. 
Loxoconcha australis, G. S. B. 
Xestoleberis margaritea, G. S. B. sp.

Cytherella lata, G. S. B. 
polita, G. S. B. 
pulclira, G. S. B. 
punctata, G. S. B. 
These 29 spp. constitute 76 per cent, of the total ostracodal fauna 
(38 spp. and vars.). 
This barnacle is closely related to one 
found in the Eocene of the London 
basin and at Bognor, in Sussex, 
England. Curiously enough, it also 
resembles in the shape of its carina, a 
species occurring in our Victorian 
raised beaches, and presumably of a 
living form which I have not yet 
been able to determine. 
The teeth of fishes are conspicuous in the Janjukian fauna of the bores, 
and mostly belong to well-known Australian genera as Cestracion, 
Galeocerdo, Lamna, Car char odon, Myliobatis, (?) Chrysophrys, and 
Diodon. The fragments of chimseroid teeth seem to belong to 
Edaphodon , already recorded from the Australian Cainozoic fauna. 
A tooth of Trygon allied to Probst’s T. rugosus is amongst the most 
interesting of the finds, and showing the wide distribution of this 
sting-ray in neogene times.
