fossiliferoTis marine beds in descending order, the following varieties being 

 met with: — Ostrea Marshii, Terehratula, a Pleiirotomaria, Trigonia, and 

 undeterminable fragments of planulate Ammonites, besides some bivalves, 

 Pholadomya granosa, and others. 



To the north-east a low tract of rocky ground intervenes between 

 this and the sandy alluvial plain of Soomraisir, in which two peaked 

 hills close together are conspicuous. 



These hills are traversed by one trap dyke at least and present a com- 

 plex assemblage of silicious stone, like ' fault rock,'

and of the soft infra-trappean grit. The relations 



are obscure, but it is probable that a line of fault occurs here. To the 

 west of these hills, a long dyke of dark trap crosses the outworks of the 

 Jooria Hills, and some smaller intrusions occur at a greater distance to 

 the east, while an isolated rounded hill of trap rises in the low ground to 

 the north. 



In this direction, just where the rocky ground meets the alluvial 

 plain, the lower Jurassic sandstones, hitherto

nearly horizontal, become much disturbed, dipping 

 northwards at various high angles or being nearly vertical, and a narrow 

 band of tertiary beds partaking of their high dip intervenes between 

 them and the alluvial plain. They are ragged, shaly, gypseous and 

 yellow, more compact mudstones, bands which are crowded with Turritella 

 angulata (?), Echinoid spines, and other fossils, such as Ostrea muUicosta, 

 Desh., Pedeu Pavri, d'Arch., Scala sub-semilamella, CeriiJiium Eookeri, 

 Area hylrida, &c. Another similar tertiary band similarly situated occurs 

 south of the village of Jooria further to the west. The arrangement 

 of these tertiary beds or their relation to the underlying jurassics is not 

 clear, the great bulk of the upper Jurassic group, usually between them 

 and the beds with which they are associated, being absent as well as all 

 the stratified traps. These great groups may have thinned out or never
