The identity of many of Dc Koninck’s species is rendered very difficult by the 
careless mistakes which are made in the reference-numbers of the figures given in the 
test, and in the Plate-Esjilanations. The j)resent is a case in point — in the test 
F. muUiporata is said to be PI. viii., fig. 4, when it should be fig. 1. 
The polyzoarium of this species would seem to have been fan-shaped, and 
certainly its features are very minute and delicate. The length of the fenestrule will 
at once distinguish it from F. fossula.

Sp. Char. Polyzoarium crumpled and curled, and probably infundibuliform, 
composed of very straight, rigid, and regular interstices, bifurcating at long iutervals, 
find retaining the same width throughout. Dissepiments short, thin, and also very 
regular. Fenestrules narrow, and long-oval. Cell-mouths arranged in three or four 
oblique rows across the interstices. Eeverse with very fine and regular longitudinal 
stris, or occasionally granular striate. 
Ohs. A tendency to wide bifurcation, accompanied by the erect, habit, give to 
this form a fan-like appearance, producing a very marked character. The several rows 
pf cell apertures on the interstices, and their absence on the dissepiments, appear to 
indicate this as a species of Polppnra. The fan-shaped polyzoarium is crumpled and 
Curled to some extent; but at present no satisfactory evidence can be adduced to show 
at the poriferous face was internal, as in Protoretepora. It is f)rovisionally, there- 
cre, referred to PoZypo/’ff. I have seen this interesting Polyzoon from two localities 
in Queensland, but from one of them, Penestella Hill, Stanwell, there are large fronds 
Cl a somewhat smaller habit, which may bo only a variety. 
P. ? SmitUi partakes of the habit of P.gigantea, Waagen and Plchl,* but is 
ecidedly smaller in all its parts ; neither does it correspond to the close retiform or 
^‘■l/llopora-Wke species usually mot with in the Carboniferous rocks of other areas. 
• ? Smithii will require further working out from additional and better nreserved 
’iiaterial. 
^ An impression (PI. 44, figs. 9 and 10) of the poriferous face of a stiff and 
ouiewhat rigid form has been obtained at Gympie by Mr. W. H. Bands. The fenestrules 
^I'c long and narrow, the interstices erect, straight, and thin. The dissepiments are 
^ ml and short, whilst the cells vary from six to nine to a fenestrule, three alternating 
Ws on each interstice, with prominent exsert mouths. The obverse surface is 
cficately striate.
