thinner than the branches j the outermost layer of the reverse surface is finely 
granuiarj but when it is weathered fine concentric striae are shown. On the 
celluliferous surface the branches are from 0*48 to 0-57 mm. in width where 
there are three^ from 0-3 to 0-38 mm. where there are two, and about 0-85 
mm. where there are. four, rows of zooecia. Bifurcation may occur within 
5 mm. 
Remarks: Pohjpora tcoodsi (Etheridge) is differentiated by its far more 
numerous, and much smaller, nodes.

St)eeimens of this s])ecies occur in the material from three of the locali- 
ties in the Kimberley District; the characters shown agree with those of the 
neotype. 
Kemarks: In Now South Wales this species is abundant in the Eene- 
stella Shales (Branxton Stage of the Tapper Marine Series) in the Hunter 
Kivcn* District, and in the riladulla Mudstones (probably about the same 
horizon in the Upper Marine Series) of the South Coast; it F not knoAvn 
from any other horizon in Ncav South Wales. In Tasmania it occurs at 
Marlborough, and in the Grange Stage near Hobart; it has l)een recorded 
by Etheridge from Queensland, and occurs in the Springsure District (Con- 
suelo Ck., two miles above Cattle Ck. ; Reid, 1930, p. 157, locality 9). It 
occurs also in the Callytharra Stage of the Wooramel R. District. Polypora 
tripliseriata occurs in the Bitaoeni Beds at Kampong Apna in Timor.

Polypora with five to six rows of zooecia, and from six to fourteen

in length, aiul rather luirrow ; nodes small, fairlg abundant. 
Tiiei‘e are i'rom 1-5 to 2-5 fenestndes vertically, and al)Out tiv(' branches 
horizontally, in 10 mm.; t!ie branches are straight, and are rathei’ rounded
