DESCRIPTION OF A LIMESTONE OF LOWER MIOCENE AGE. 289 
Some small, rather thick-shelled examples of this pelagic 
species occur in the limestone from Papua. It is one of 
the species accompanying Lepidocyclina in the Miocene 
limestone at Batesford near Geelong. 
GLOBIGERINA CONGLOBATA, Brady. 
Globigera conglobata, Brady, 1879, Quart. Journ. Micr. Sci., 
Vol. xix, N.S., p. 72. Idem, 1884, Rep. Chall. Vol. rx, 
p. 603, pl. Ixxx, figs. 1-5; pl. Ixxxii, fig. 5. 
A few typical examples of this stoutly-built, pelagic 
foraminifer, so frequently met with in tropical coral-reef 
deposits, both fossil and recent, occur here. The closely 
adpressed outer chambers and their excessively thick walls 
distinguish the form from others of this genus. 
Fam. Rotaliide. 
Genus TRUNCATULINA, d’Orbigny. 
TRUNCATULINA cf. LOBATULA, Walker and Jacob sp. 
Nautilus lobatulus, Walker and Jacob, 1798, Adams’ Hssays, 
Kanmacher’s ed., p. 642, pl. xiv, fig. 36.

Chall., Vol. 1x, p. 660, pl. xcii, fig. 10; pl. xciii, figs. 1, 
4,5; pl. cxv, figs. 4, 5. 
A partial section of a thin-walled Truncatulina, probably 
nearest to the above species, occurs in the Papuan Lepido- 
cyclina rock. Itisacommon shallow-water form in almost 
all existing seas.
