AUSTRO-HUNGARIAN GONIOPOR^E. 127 



Calicles " small," very shallow, " irregularly separated by level ccenchyma from which 

 they are not separated by distinct walls." In other words, the walls are a level reticulum of 

 irregular thickness. Septa 12-14-16-18 or 24, rather thick, straight or slightly wavy, with 

 irregular synapticulae projecting from their sides often joining the septa ; the inner ends of the 

 septa when not fused together are rounded, and often bent up and then not distinguishable from 

 the " pali." These pali seem to be rather the free ends of the columellar tangle ; they are 

 quite irregular in size, number, and arrangement. 



The most important point about this coral is that it is a cretaceous fossil, and therefore 

 one of the earlier known Goniopora;. There can, I think, be little doubt but that it is a Poritid. 

 The simple growth-form, like a series of caps fitting over one another with a succession of 

 edges ; the number of septa ; the fact, brought out clearly in both figures, that the septa fused 

 together * ; are enough to establish it as a member of the genus. 



Reuss speaks of it as being rare in the Hippuriten-Kalk near Koritzan, Bohemia. While 

 Posta says it occurs (not rarely) in the Cenomanian strata of Koritzan and of Pfemyslan, and 

 that the specimens are found of all sizes.

This is one of two corals described by Posta under one name. For the description of the 

 form which was figured, see Goniopora Bilin 1. It does not appear to differ very much 

 from G. Koritzan 1. 



Another coral, called by Posta Porites spissus, from this locality, does not seem to me to be 

 a Poritid at all on account of the character of the wall, as shown in his published figure, I.e. pi. i. 

 fig. 5 a and b. Such a perfectly regular costal wall I have never yet seen in any member of 

 the family. But both text and figure are difficult to interpret.

Description. — Corallum forms irregular nodules up to 12 cm. round, sometimes narrowing 

 towards the base, stock consisting of concentric layers. 



Calicles polygonal, wall frequently incomplete ; the wall-ccenchyma seems to be thinner 

 and less developed than in Goniopora Koritzan 1, and at the same time more reticular. Sep to 



* In describing his Porites textilis, the author definitely states that the septa in his Porites 

 Michelini are branched, I.e. p. 28.
