200 REMARKS ON FOSSILS OF PERMO-CARBONIFEROUS AGE, 



(1) Ironstone Ridge, twenty-five miles south-east of Yeeda 



Station, on the Fitzroy River. 



(2) Mount Marmion, near the junction of the Lennard and 



Meda Rivers, 



(3) Mount North Creek, Napier Range. 



(4) Lennard River Gorge, Napier Range. 



(5) Barrier Range Homestead, Napier Range. 



(6) Oscar Range, north-east side. 



Before proceeding to a description of the organic remains, a 

 short sketch of the Pindan Sands and of the recognised Carbo- 

 niferous beds, extracted from Mr. Hardman's Reports,* will not 

 be out of place. 



(1) The Pindan Sands and Gravels are the youngest of the 

 Geological formations in the Derby area, excepting, of course, 

 recent alluvial deposits, and were provisionally called by Hardman, 

 Pliocene. They were termed "Pindan" — "from principally occur- 

 ring in the thickly wooded undulating country termed by the 

 natives 'pindan.'" These beds consist of reddish sands with pea- 

 like nodules of ironstone, gravels, coarse conglomerate, grits and 

 sandstones, the result of the consolidation of detrital deposits 

 by carbonate of lime, or ferruginous material. There are no good 

 sections, but these beds are known to be from twenty to thirty 

 feet thick. About ten miles south of the Feeda Station where 

 they attain this thickness, these sands and gravels rest on " coarse 

 sandstone, probably of Carboniferous age." No fossils were found 

 in the Pindan beds by Mr. Hardman, " but there can be little 

 question that they are of comparatively recent age. I have 

 classified them provisionally as belonging to the Pliocene period."! 

 Mr. Hardman further added that thick beds of consolidated iron- 

 stone conglomerate were associated with the sands and gravels 

 in places, often assuming the form of low, flat-topped, and conical 

 hills, t
