The ground in the neighbourhood of NuUia is an open alluvial- 

 looking plain, the surface of which is strewed 

 with rolled fragments of silicified wood. 



The streams, however, near the village expose gray, olive, and pur- 

 ple shales, flaggy in places, with yeUow, harder, calcareous and marly 

 bands. These undulate at low angles, and are overlaid by very thick 

 bedded, soft brown sands (portions of which are solidified by calcareous 

 infiltrations), with clay nodules and cylindrical bifurcating concretions. 

 The sands appear to be the prevailing rocks of the coimtry, and exhibit 

 various unconformable junctions with the beds below, their basal portion 

 being generally conglomeratic, and bands of the same occurring also at 

 higher levels. 



In the sands, large logs of decomposing fossil wood occur. The 

 cores of these are silicious, and may have furnished the rolled fragments 

 found over the surface of the ground. The beds beneath contain but 

 few fossils, some univalves, a large pecten-like shell, annelid or crustacean 

 tracks, and indefinite fueoid impressions only being found. 



Between the Nullia and Kotara rivers the plain is flat, or slightly 

 undulates, and the boundary between the alluvium and the newer ter- 

 tiary ground being exceedingly indefinite has been somewhat arbitrarily 

 drawn. 



* In Colonel Grant's paper several references are made to a village called Soomrow, and 

 one of his shells (Pecten SoomromensisJ is named after it. He describes it as ten miles 

 north-cast of Jukow, but no village of the name could be found, and it is conjectured 

 that Trummo is the place meant.
