Fauna of the Kalimnan Series. 
The foregoing Janjukian series passes, in these boring samples, into beds 
containing first a mixed fauna (Janjukian and Kalimnan), and then into 
typical Kalimnan beds. The glauconite sands and marls appear to express 
a passage series containing the two formations, and these pass up into true 
Kalimnan shell-marls with Glycimeris and Limopsis. Generally speaking, the 
Kalimnan of the Mallee is, like that of the Hamilton area, of fairly shallow- 
water origin, but in some cases, as in Bore No. 5, there are indications of a 
deeper water facies. The genera usually represented in the Kalimnan of the 
bores are such as are found on rocky shores or shallow sandy flats; but 
occasionally much deeper water conditions may have prevailed, as seem to 
be shown by some brachiopods (Terebratulina), the smaller mollusca, the 
ostracoda ( Krithe ) and the foraminifera ( Nodosaria, Frondicidaria , and 
Uvigerina). 
Among the more noteworthy Kalimnan fossils of the borings we may cite 
the following :— 
Ammodiscus ovalis, Chapm... 
Polystomdla striatopunctata , 
F. and M. sp., var. evoluta , 
Chapm. 
Holcotrochus cremdatus, Den- 
nant 
Bathyactis beaumariens is, 
Dennant 
Lissarea rubricata, Tate sp. .. 
Crassatellites kingicoloides, 
Pritchard 
This form is a depauperated modifica¬ 
tion of species like A. robertsoni, H. 
B. Brady sp., and A. auriculus, 
Chapm. The Carbopermian speci¬ 
men from Pokolbin, New South 
Wales, figured as Ammodiscus sp., 
should be referred to this form. 
This variety of a well-known living 
species of foraminifer is probably 
indicative of shallow water. A close¬ 
ly allied variation is that figured by 
Heron-Alien and Earland as var. 
sdseyensis, from the Pleistocene of 
Selsey, England. This is evidently 
an instance of the dual divergence 
of a widely distributed type form, 
producing almost identical results. 
This neat, simple coral was hitherto 
known only as a living form, at Cape 
Borda and St. Vincent’s Gulf, South 
Australia. 
This is a good zone fossil, as it is prac¬ 
tically restricted to Kalimnan beds 
in Victoria. 
The occurrence of this little species in 
the Mallee bores is its first record in 
the fossil state, the horizon being 
Kalimnan. 
A species characteristic of the Jemmy’s 
Point beds, Gippsland, and lately 
recognised by Mr. C. J. Gabriel and 
the writer in the Beaumaris beds. 
This occurrence, along with that of 
Turritdla pagodula, another Jemmy’s 
Point fossil, seems to indicate an 
open communication with the Gipps¬ 
land and Port Phillip Kalimnan 
sea, rather than with that of the 
Hamilton area, from which locality 
these species are absent.
