The noteworthy species of the Janjukian of the borings may be sum¬ 
marized as follows 1 :— 
Lithothamnion ramosissimum, An important calcareous alga in the 
Reuss sp. Miocene in Europe, and characteris¬ 
tic of the polyzoal rock of the present 
series. 
Previously known from the Balcom- 
bian (probably near the top of the 
beds), at Muddy Creek, as well as in 
the Miocene of the New Hebrides, 
in which it was found by the writer 
associated with typical Miocene 
Lepidocyclince in limestone collected 
by Sir Douglas Mawson. 
This foraminifer was found living off 
South Australia till within Pleisto¬ 
cene times. It is now found in 
lower latitudes. The form also 
occurs in the Kalimnan of this 
series. 
Orhitolites complanata, La - 
marck 
Frondicularia lorifera , Chapm. This species occurs in Janjukian, and, 
doubtfully, in Kalimnan samples. 
A striking species. 
Carpenteria proteiformis, Goes A Balcombian and Janjukian form in 
Australia. It is here restricted to 
the Janjukian series. 
Pulvinulina 
Chapm. 
scabricula , Restricted to the Janjukian. Also 
found at Batesford. 
P. calabra , Costa sp. 
Gypsina howchini, Chapm. 
First described from the Italian Ter- 
tiaries; it has since been recorded 
from the Tertiary marl of Whainga- 
roa Harbor, New Zealand, named 
Rosalina thiara , by St ache. This 
occurs in a mixed sample from the 
borings, which has a preponderance 
of Janjukian fossils. 
A restricted Janjukian fossil, known 
previously only from Batesford. 
Operculina venosa, Fichtel and This interesting form is restricted to 
Moll sp. the Janjukian of the bores. At the 
present day it is confined to tho 
Great Barrier Reef, Queensland, and 
the East Indian Archipelago.
