The Victorian specimens are few-chambered, and are somewhat flattened, 
in this respect resembling the fossil forms found in the gault clays of England. 
Rare in Samples 1 and 2 from Brown’s Creek, Victoria. 
Haplophragmium canariense, d’Orbigny, sp. 
Plate XXII., Fig. 2. 
Nonionina canariensis, d’Orbigny, 1839, Barker-Webb and Berthelot, 
Hist. Nat. lies Canaries, vol. ii., pt. 2, “ Foraminiferes,” p. 128, PI. II., Figs. 
33 and 34. 
Haplophraqmium canariensis , d’Orb., sp., Flint, 1899, Rep. U.S. Nat. Mus., 
1897, p. 277, PI. XX, Fig. 3. 
This neat form is represented here by a small specimen from each of the 
samples, Nos. 1 and 2. 
GENUS LITUOLA, LAMARCK. 
Lituola simplex, sp. nov. 
Plate XXII., Figs. 3 and 4. 
Test roughly sub-circular, thin ; surfaces and outline irregular ; structure 
of test coarsely arenaceous. Indications of an internal spiral conformation 
are seen on the lateral surfaces of the test. The fractured portions of the test 
show a close labyrinthic condition of the interior. The later part of the 
shell tends to become rectilinear. In this latter feature it bears some 
resemblance to Haplophragmium agglutinans, d’Orbigny, sp., but the compact 
non-septate character of the interior shows its relationship to be rather with 
Lituola. Longest diameter of the test - 55mm. Not uncommon in Sample 1. 
Rare in Sample 2. 
GENUS AMMODISCUS, REUSS. 
Ammodiscus incertus, d’Orb., sp., var. macilenta, nov. 
Plate XXII., Fig. 5. 
This variety, which is here a constant form, is distinguished from the type 
form by its excessively thin arenaceous test. The successive whorls are much 
compressed, and especially those of the later part of the shell. The last whorl 
has a tendency to become hollowed along the central area of its surface. 
Diameter of test '4mm. 
The extreme tenuity of these and other associated arenaceous forms points 
to calm conditions when these deposits were laid down. Not uncommon in 
Sample 1. 
GENUS CYCLAMMINA, BRADY. 
Cyclammina complanata, sp. nov. 
Plate XXII., Fig. 7. 
Test spiral, discoidal, much compressed. Margin sub-acute or slightly 
rounded, undulate. Whorls partially evolute. About twelve chambers to the 
outer whorl in full-sized specimens. Septal lines sinuous. A deep umbilical 
depression usually present. Surface of test smooth ; in worn specimens pitted, 
showing evidence of the internal cancellated structure. In median section 
the main bulk of the chambers is seen to be occupied by labyrinthic shell- 
structure. Diameter of test from 1 to 2mm.
