Obs. — Four additional specimens of Rugosa have been obtained 

 l)y Mr. Jack; three of them are from the Middle Bowen Series at 

 Kyunga, near Banana, and were presented to the Queensland 

 Geological Survey Collection by Mr. — Sutherland, whilst the 

 fourth is from the same series in the type district, and was 

 collected by Mr. Jack four and a half miles up Parrot Creek, 

 Bowen River. 



Two of the Kyunga corals possess the same robust turbinate 

 appearance, thick wall, and stout septa as those of Zaphrentis 

 rohas'a, De Kon., of the N.S. Wales Permo-Carboniferous. If 

 anything, the accretion gi-owths are a little more marked, but the 

 rugse are identical, and so appear to be the transverse frills 

 ornamenting the latter. On the other hand, the septa are 

 increased to fifty, which is a marked departure from the number 

 present in the species named. 



The third coral although of sutHciently well marked character 

 to pass for a more slender individual of Z. robusta, possesses but 

 forty-five septa. With this discrepancy, in an otherwise apparently 

 similar series, it may perhaps be well to pause before definitely 

 referring the specimens to Z. rob?osta, and await the advent of 

 additional material. 



The coral from the type district is also a turbinate, and 

 little curved form, possessing fifty-eight septa. In the robust- 

 ness of its habit it resembles the preceding specimens. The calice 

 is deep with a very thick wall, the rugaj corresponding in part 

 with the interseptal spaces. The septa in the calice are short, 

 thick and somewhat wedge-shaped, and much thickened with
