ing an abrupt scarp towards tlie trap hills. Cropping out from 

 beneath this crag, and forming the low ground near, is a peculiar 

 green earthy strong-bedded sandstone, full of earthy tubular casts. 

 .The bedding surfaces are studded with large specimens of Trigonia 

 closely allied to, but specifically distinct from, T. Smeeii and a Trigonia 

 almost identical with the south African ventricosa of Kraus. This 

 fossiliferous band may represent that with large Trigonia and CucuUecs 

 near Hurroora on the other side of the great intrusion. Its horizon 

 is difficult to fix on account of probable dislocation connected with 

 the occurrence of the trap, and the association of the Oomia band 

 with beds of upper or upper transition aspect differs as much as the 

 nature of the rock does from that containing T. Smeeii in greater pro- 

 fusion, at the distant locality of Idderghur east of Chobaree in Wagur. 

 Here at Oomia the band seems to occupy a position not far beneath 

 the upper group, while in Wagur, beds both above and below those 

 with T. Smeeii contain Ammonites and several other marine forms. 



In the low ground somewhat more than a mile to the north-west 



Zcmia, north-west of under some soft white sandstone are nearly 



°'^^' horizontal olive sandstones and dark shales. 



In these beds large and small plant fragments and some obscure bivalve 



shells occur, while close by an imperfect Zamia impression on a piece of 



the shale was picked up, but none could be found in situ.

low ground near Lakapoor. They are steep in 

 all directions and faced by a bold cliff, south of that village, which 

 turns at Mal-Gandara so as to overlook Oomia. The high cliff and 

 most of the hills are formed of white and purple, sandstones, conglo- 

 meratic beds and ferruginous shales. But the summit and some peaks 

 near it are composed of basaltic and softer trap. No lines of flow or
