a branclimg coral from Glen William and Burragood, wliicli he referred to 
S. ovata, hut the presence of pores induced him to place it in Fcivosites} 
This has already been explained, and will he referred to again later. 
It is possible, and even proljable, that all the species which have been 
described from Australasia do not represent separate and distinct organisms — 
I am inclined to think they do not — l)ut this much is certain, they do represent 
different conditions, which, so far as the specimens themselves are concerned, 
seem permanent within certain circumscribed areas, and, therefore, for all 
reasonable purposes, such specimens may be considered distinct, until actual 
demonstration shall prove the identity of any one with another. Bor instance, 
Stenopora ovata, Lonsdale, and S. australis, N. & E., are, to all intents and 
purposes, identical in general characters, but the former is known to possess 
acanthopores, the latter not ; the peculiarity in this case being that no 
specimen of S. atis trails, so far examined from the Bowen Biver Coal-field, 
the only locality known for this coral, has been observed to possess acantho- 
pores — yet, in the mind of the Writer, the two “ species” seem to bo one.
