INTRODUCTION. 
'Thin pajior f>res('nts t\u) rosiilts of tlio oxaniination of a iiuidIkh- of rock 
samples and otluM* material (containing foraminifera from the I*ormian of the 
North-West Di\'ision of Wi^stiwn Anstralia. I'hc s])(tcim('ns w'l^re coll(K*t('d by 
Mr. Htairy (Viley and Dr. U. 'I’cicliert and. witli two exceptions wlii(cli will 
be noted lati'r, are all from beds forming pai't of tlie Wandagei^ Stagic of Dr. 
H. (1. Raggatt (UKJh) and latter authors. 
Foraminifera ha.\-e not Ixcon prtw'iously i'ecord(‘d from beds of tfac W'an- 
dagee Stagi* and, at first glanet^, the liard, brownish, impur(c limestoiK's and 
calcareous, tine-grained sandstones, in placi‘s highly h'l’rugiiHiUs, from these 
btnls apptTir indaA’ourable to theii* occui‘r(‘nc(L lA»rtunat<*ly a- eolkudion of 
tht^ largtM* fossils, pr(‘sented to the Must'nm of the Nuetorian Min<*s Depart- 
ment in 1 9‘hS by Mr. Htairy (V)l(cy, include(l a, speeinaai on the weatlasred 
surfatce of which exampkes of a. largi^ foraminih'r, now identiiitMl as ////per- 
finimina coleyi^ sp. nov,, were r(^(‘Ognis(‘d. Mr. ('okiy and Dil 4\4chert after- 
wards forwarded many samples trom which the foraminifea’a now' desicribed 
were obtained. Tlu'i calcareous nature of th(5 rock in most tcasf's enables the 
sandy-shelled foraminifea’a., which constitute almost thi^ whok^ of the fauna., 
to be freed from the surrounding mati*ix by imtiuvrsing the sani])I(' in wiatk 
hydrochloric acid. The results of this treatment have bfMni surprisingly 
successful, for, although the riumixa* of spoci<^s is not large, tln^ nuinbia*, size 
and piM^serv’ation of tlu^ specimens is remarkabkL Other sp(T*im<’ns were 
identified on the surface of those sampk\s which (•oiild not 1)(^ treatcul with 
acid and a number were obtairuMl from wt'uthenid sandy shale. 'Tw(4ve 
genera and fifttnai species of forarninihua are^ re(U)rded, of whicli twelvt^ spocies 
are di^scrilxM as new. Th(m> is also what is bifievcul to he a ncAv tubicolous

In a recent paper, Dr. Ttnchert (1939) has dealt with the stratigraphy 
of the Permo-Carboniferous soijuonco of the Nortli-Wc^st Division of W'estern 
Australia. The sefpRMioe has biHui divided by Raggatt (1931)) and others 
into the following stages, wliieh are given in doscend/ng ordiu’ : 
MMndagc'o Stage 
KenncMly Stage. 
Pyro Stage. 
Wooramel Stage. 
Callytliarra Stage. 
Ij^'ons Stage.
