Mr. Moore's specimen is from the district of the Upper Maranoa. 



In the Transactions of the Royal Society of N. S. Wales for the 

 year 1882, Rev. J. E. T. Woods, F.G.S , mentions Crioceras 

 australe from the Palmer River Goldfields, and supplies two 

 photographs (Plate X., figs. 5 and 6). 



The specimen described in the present Paper is from Yamba 

 near Rockhampton, and was presented by R. N. Bell, Esq., in 1875. 



EXPLANATION OF PLATE. 



I late 1 . — Septa of Crioceras australe, {?) drawn to the scale of about f nat. 

 size. The development of the half series of lobes represented, 

 from the median external to the median internal line is about 13£ 

 inches. The length of the septa from the lower end of the larger 

 saddle up to the tip of the superior lateral lobe is about six inches. 

 In order to show how the ramifications of two successive septa 

 interfere with each other, the following ones have been partly 

 drawn in dotted lines and corresponding letters put on similar 

 parts of both walls. 



Plate 2. — To the scale of about J. The dotted circular line below the inner 

 whorl represented, shows the space between the whorls which as 

 already said, although close together are not in contact. The 

 section on the left of the figure shows also that space.
