DESCRIPTION OF A LIMESTONE OF LOWER MIOCENE AGE. 299 
4. Summary. 
The following organic remains have herein been deter- 
mined as from the Lepidocyclina limestone at creek head, 
one and a half miles inland from Bootless Inlet, Papua:— 
Lithothamnion ramosissimum, Reuss sp. 
Miliolina sp. 
Textularia rugosa, Rss. sp. 
Globigerina bulloides, d’Orbigny. 
a triloba, Rss. 
A conglobata, Brady 
Truncatulina cf. lobatula, W. and J. sp. 
Carpenteria capitata, J. and C. 
Amphistegina lessonii, d’Orb. 
Operculina complanata, Defr. sp. 
Heterostegina depressa, d’Orb. 
zs margaritata, Schlumberger. 
Cycloclpeus cf. communis, Martin. 
Lepidocyclina sumatrensis, Brady sp. 
ets Andrewsiana, J. and ©. sp. 
= Murrayana, J. and C. sp. 
Verbeeki, Newton and Holland sp. var. 
papuaensis, nov. 
Echinoderm remains, indet. 
Polyzoa, indet. 
Fish tooth, cf. Chrysophrys. 
Amongst these organisms the important factors in the 
determination of the Lower Miocene age of the limestone 
are the genera and species of Carpenteria, Heterostegina, 
Cycloclypeus and Lepidocyclina. 
A comparison of the Papuan series of fossils may be 
profitably made with those given in the table of stages in 
the Cainozoic series of Borneo by H. Douvlllé.* This was
