nature of the rocks on each side corresponding, though there is some 

 difference in the sets of marine fossils which they contain. 



It is possible that concealed faults may do much to obscure the 

 relations of this ground ; and there is room enough to imagine that the 

 continuation of the Wagir rocks is concealed in the Eunn and the low 

 grounds of the islands, or that more complicated contortions are hidden 

 there from view, and that the Putchum and Kurreer beds are much 

 lower than anything seen in Wagir. 



However this may be, the calcareous beds of West Wagir disappear 

 over the rest of that tract in a manner most consonant with the supposi- 

 tion of their having thinned out or being replaced by other beds. 



Again, in the Lower Jurassics, along the north of Kutch Proper, 

 the character of the rocks is subject to some 



Changes in the Lower a i • 



Jurassics, north of Kutch change. At their eastern extension calcareous 

 beds are comparatively scarce, and the shales 

 are very thick in the centre of the hills. In the Juria hills, 

 north-north-west of Bhooj, whitish calcareous beds or earthy lime- 

 stones are abundant, and here the golden oolite appears in force. 

 This again appears with calcareous beds of less thickness to the 

 westward near the Keera hill ; and these calcareous strata form the 

 quaquaversal dome of Manjal hill south of Nurrha, where the oolite is 

 represented by a few blotches only, the limestones being still traceable in 

 the direction of Jarra beneath the cliffs. The whole of this ground 

 furnishes about the same .varieties of marine fossils ; and the shales which 

 are locally thick to the east also appear in greater force to the west than 

 in the intermediate ground.
