178 BLANFORD : GEOLOGY OF WESTERN SIND. 



Calopleurus forlesi, Schizaster, sp., Ecldnolampas spheroidalls, and some 



mollusca. East of the scarp there is a low ridge having- a gentle eastern 



slope. This ridge consists of still higher Gaj beds, laminated and banded 



yellowish sandstones, very irregularly bedded. Upon these, Manchhar 



beds rest near Thana Shah Beg. 



The Myher plateau extends for about 25 miles to the southward, 



the scarp running parallel to the river, but at a 

 Myher plateau. 



distance of about 4 or 5 miles from the stream. 



Farther south the plateau decreases in elevation until it becomes broken 



up into minor ridges on the borders of the Gadab plain north of Karachi. 



The Nari beds occupy the Habb valley from the mouth of the Kand 

 Nari beds of Habb stream, where the Habb commences to form the 

 valley south of Kand. frontier of Sind, to the sea. They sweep round 

 the southern extremity of the Hamlig range east of the river, and of 

 the Lakhan to the west ; and apparently extend to the foot of the great 

 Pabb range, a lofty chain to the westward of the lower Habb valley. 

 The Hamlig and Lakhan ranges are apparently anticlinals of Khirthar 

 beds, like so many of the hills farther to the eastward. 



At Kand Thana, the Nari beds dip south-east about 20°. Farther 

 south the dip changes to east-south-east or east, and the same general east- 

 wardly dip continues for a long distance, the inclination varying. On 

 the banks of the Kand river, near the Thana, some false-bedded dark- 

 brown calcareous grit is seen, containing Turriiellce. Near the Habb a 

 low range of hills extends for a considerable distance along the left bank 

 of the river, south of the spot where it is joined by the Kand stream. 

 Some of the beds near the latter, on the eastern side of the range, consist 

 of fine greenish-grey sandstone, containing round concretionary nodules, 

 some of which are perfect spheres, from 2 inches to upwards of 2 feet in 

 diameter ; others are spherical above, but flattened at the base, and 

 when, as frequently happens, the concretion itself has fallen out, a 

 depression is left on the surface of the sandstone, precisely resembling 

 a platter in shape. This bed, with its peculiar concretions, is found in 

 other parts of the Habb valley.
