are much broken and somewhat irregular. Near the mouth of the Habb 

 there is a synclinal, and Nari beds re-appear on the coast. East of the 

 synclinal the Nari sandstones are seen with a reversed dip in a low range 

 of hills running from north-north-east to south-south-west. 



At the jutting rocky point on the eastern side of the Habb, opposite 



Raised oyster beds and the san< ^ spit which forms a bar at the mouth of 

 the river, there is a raised oyster bed about 50 feet 

 above high water mark. There are also oyster shells attached to the 

 rocks, about 10 to 15 feet above high- water mark, east of Cape Monze. 

 On the flat or undulating 1 ground of the Nari rocks between the two 

 Gaj ridges that unite at Cape Monze, recent marine shells are scattered in 

 considerable numbers, the most common being two forms of Turbo (a 

 Senectus and a Lnnella), both species living on the coast. Nearer to the 

 shore many kinds of shells are scattered about. The oyster beds clearly 

 prove that elevation of the land has taken place at no distant period, and 

 the remaining shells may have been left behind by the sea when it over- 

 flowed the plain. The circumstance that forms of Turbo are so much 

 more common than other genera may perhaps be due to pearly shells 

 resisting the influence of exposure longer than other kinds. At the same 

 time the Turbo shells may have been brought by men, and the animals 

 used for food, but nothing was noticed like the shell heaps (Kjokken- 

 moddings) usually produced under such circumstances. 



Turning eastward from Cape Monze, Gaj beds occur for a few miles, 



Manchhar beds east of then Manchhar beds appear resting upon the Gaj. 

 Cape Monze. rp^ e Manchhar rocks are fairly seen between 6 and 



7 miles from the Cape in some ravines ; farther to the eastward the plain 

 between the Gaj hills of Haji Zaraand the sea is covered by alluvium for 

 the most part. The Manchhar beds at the place just noticed present in 

 part a very peculiar character ; a portion of them consists of grey sand- 

 stones as usual, but other beds are whitish sandy clays with interstrati- 

 fications of very thin laminated papery sandstones. These closely 

 resemble a very characteristic form of the Makran beds, 1 so largely
