RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 
deposit is a coarse white and iron-stained sand, identical in appearance 
with the Kalimnan sends of the Melbourne district, and like them, 
in all probability of }Kalimnan age. The view here maintained, 
that the main volcanic series occurs above the yellow limestone and 
under the Kalimnan grits, is the same as brought forward by Mr. 
Daintree as early as 1861. A reproduction of Daintree’s sketch- 
section of the cliff at Curlewis (Ad 12) is given in my paper on some 
Tertiary fossils.* On a recent visit to this place (shown on Quarter- 
sheet 23 sw) the section of the cliff showed a bed of tenacious blue 
clay resting on an ash bed, and above this a polyzoal limestone 
about 5 feet thick. This is surmounted by about 13 feet of basalt, 
and on this a thin layer of hill wash. 
The present occurrence of older basalt as high as the top of the 
Janjukian is unique in the experience of the writer, for it generally 
occurs interbedded with or underlying the sedimentaries of that 
epoch. It further strengthens the view that the Janjukian episode 
was not only intermittently subject to volcanic disturbance, as 
already found in-the Anglesey district by the occurrence of tufis 
interbedded with the sedimentaries,j but that the effusions did not 
cease until about Kalimnan times. 
Fyansford.—The Orphanage Hill section consists of grey clays 
passing into yellow clays. These beds probably represent an 
argillaceous phase of the Janjukian. The molluscan fauna has not 
been completely worked over, but by comparing the list of Hall 
and Pritchard, it will be seen that five species recorded by them,t 
viz., Terebratula vitreoides, T. Woods, Natica gibbosa, Hutton, Pleuro- 
toma haastii, Hutton, Limopsis insolita, Sow. sp., and Cardita gracili- 
costata, T. Woods, are restricted Janjukian fossils. The remainder 
are persistent types and widely distributed forms. It is probable 
that by diagnosing the new forms to be found in this locality the 
proportion of restricted species will be raised. The paleontological 
evidence, although leaving much to be desired, points to affinity 
with the Janjukian rather than to the Balcombian, since not one of 
the species enumerated by Hall and Pritchard is confined to Bal- 
combian. 
In my paper on “ A Revision of the Species of Limopsis in the 
Tertiary Beds of Southern Australia,”’§ in following the general 
usage I there placed the Orphanage Hill beds as well as the Corio 
Bay Beds in the Balcombian series. The above evidence, however, 
is sufficient proof to my mind of their affinities with the younger, 
Janjukian, series. 
Moorabool Valley and Batesford.—There is no doubt as to the 
position of these beds in the Victorian Cainozoic series, for their
