The coral called L. hasaltiforme does not appertain to the European 
species of that name ; neither does it belong to the genus, nor is it Carbon- 
iferous, I have already explained^ that Carboniferous rocks do not occur, so 
far as -vve know, on the Murrumbidgee lliver, the locality from which the 
specimen w^as said to have come. The coral so named by Ee Koninck I have 
collected from the blue-black Siluro-Devonian (so-called) limestone of Cave 
Elat, at the junction of the Murrumbidgee and Goodradigl)ee Ptivers. It is 
a Cyathophyllmn, and only on a casual examination could have been mistaken 
for L. hasaltiforme. 
The locality of Ee Koninck’s LithostroHon irregulare, as given in his 
work, is eertainly a Carboniferous one ; but I cannot avoid the impression that 
a mistake has arisen in so assigning the speeimen. It is suspiciously like, in 
general appearance, a coral I have described^ as Tnjplasma Lonsdalei, from 
the Upper Silurian of Hatton’s Corner, near Yass.

Sp. Char . — Corallum of medium size, conical, compressed towards the 
base ; section circular. Septa forty to forty-two, with an equal number of 
secondary lamella? ; primary septa generally straight, here and there a little 
curved, proceeding direct to the centre of the calico, untwisted ; secondary 
septa rather less than half the length of the primary ; dissepiments highly 
developed, extending inwards for half the length of the primary septa, 
irregular in direction, convex outwards, oblique, or at right angles to the 
septa; vesicles small and irregular in shape; stereoplasma well developed 
forming an outer zone rather more than a third as wide as the corallum. 
Tabulate area very small, if present. 
Ohs . — The systematic position of this coral is somewhat ambiguous. 
The quantity of vesicular tissue would indieate Cyaihophyllum as its genus, 
whilst the manner in which the septa approach the centre, and the slight 
evidence of tabulae point to Zaphrentis.
