N. Irwinensis may be compared with a similar feature in 
N. vertebralis, Batsch.; but the examples now under considera- 
tion do not exhibit the transparent shell substance in the septal 
bands which gives the vertebral appearance to Batsch’s species. 
How far this feature may have been modified by age in the West- 
ern Australian species it is impossible to say. In other respects 
there is but slight similarity between the two species. 
The genus Nodosaria (including Dentalina) is but sparingly 
represented in rocks of Paleeozoic age. In Brady’s ‘Monograph 
of the Permian and Carboniferous Foraminifera”* only three 
species are recorded, and the whole of these belong to the Permian 
or newest member of the division. A true Modosaria was dis- 
covered by the present writer in one of the minor limestones of 
the lower Carboniferous series of Northumberland,t and a mem- 
ber of the same genus occurs in the Permo-Carboniferous rocks 
of Tasmania.{ In the Carboniferous Limestone of the Northern 
Hemisphere its place seems to be taken by Nodosinella, a group 
of foraminifera with finely arenaceous tests, and which in form 
are to some extent isomorphic with the hyaline Nodosarie of 
newer formations. 
FRONDICULARIA WoODWARDI, sp. nov. 
Ref.—Frondicularia species, Report of Fifth Meeting of the 
Aus. Ass. for Advancement of Science, Adelaide, 1893, p. 366. 
Test elongate, tapering, compressed, and subject to to consider- 
able variation in external form. Oral end broad, rounded, and 
regularly curved. Aboral extremity obtusely pointed. Peri- 
pheral margins rounded. Segments from seven to ten in number, 
gradually increasing in size, acutely arched. Final chamber relat- 
ively large, inflated, and lobulated. Sutures flush, marked by 
clear shell substance. Length of shell equals twice or three times 
the breadth. 
Length of fine example, 5}, in. 
This pretty little shell somewhat resembles /rondicularia com- 
planata, Defr., but differs from that species in its elongate contour, 
fewer chambers, and conspicuous final segment. The segmenta- 
tion is also less acute, particularly in the later chambers, which 
approach to a regular curve. A somewhat similar example to 
our species was figured by Messrs. Jones and Parkers from the 
Upper Trias of Chellaston, Derbyshire. The authors referred to 
designate the form figured by them as a “variety” of Frondicu- 
laria complanata, Defr., but without further description. The
