A comparison of this list with that given for Boggy Creek 

 shows some variation in the species represented. This is doubt- 

 less owing to the more littoral character of the Moitun Creek 

 deposit. Its fauna is apparently allied to that at Table Cape, on 

 the north coast of Tasmania, which is admittedly a strictly 

 littoral one. 



The outcrops of the fossiliferous ironstone at Moitun Creek are 

 confined to the steep southern bank : beyond the flats on the 

 north the strata consist of the devonian sandstones and con- 

 glomerates, which continue up to Iguana Creek, the weir on the 

 Mitchell, and thence for a long way northwards. It is especially 

 important to note that there is no limestone at Moitun Creek, nor 

 indeed for several miles to the east to it ; the actual limits of this 

 rock on the Mitchell will be indicated directly. 



At the mouth of Lucas Creek, which is about two miles east in 

 a direct line from the Moitun Creek junction, there is a bold clifl 

 •on the Mitchell called Perry's Bluff. The sediments are mostly 

 very fine, and often almost a pipe clay. The strata are horizontal, 

 And from the surface downwards consist of : —
