Family — TEXTULARIIDiE. 
Genus — MONOGENEltINA, Spandel. 
Monogenerina pyramidis, sp. nov. 
(Plate III, Fig. 5.) 
Description . — Test elongate, tapering, consisting of about seven 
chambers, each a little higher than broad. Primordial chamber ellipsoidal. 
Pet ween each chamber there is a marked separation line. The summit of 
each chamber is centrally perforated in succession, and the border of each 
perforation, or stolon passage, is turned do w awards into the chamber cavity. 
Shell-texture hyaline, finely and densely perforated. Length of figured 
specimen, 1*5 mm. 
Observations. — The Genus Monogenerina was established by Spandel 
for the inclusion of those forms allied to Bigenerina which have the 
communication between chambers arranged along a single axis running 
vertically through the median line of the shell. Monogenerina pyramidis 
differs from the species previously described by Spandel 1 from the Permo- 
Carboniferous of Kansas, North America, in having a gently tapering and 
straight-sided test, the chambers having a sub-rectangular form in median 
section. 
Occurrence. — In thin slices of the limestone from Pokolbin, New 
South Wales. Not uncommon. 
Genus — VALVULINA, d'Orbigny. 
Valvulina btjlloides, Brady. 
(Plate I, Figs. 9a, c. 
Valvulina bulloides , Brady, 1876, Mon. Carb. and Perm. Foram. (Pal. Soc.), p. 89, PI. IV, 
Figs. 12-15. 
Observations. — This species, as Dr. Brady remarked, bears many points 
of similarity to the hyaline type, Globigerina. It is, however, more irregular 
in the shape of the last-formed chambers, and its shell-structure is sub- 
arenaceous. 
Occurrence. — One specimen was found in the washings from the 
decomposed limestone of Wollong.
