1866.] the Western Himalaya and Afghan Mountains. 163 



a. The bed with the spur brought up again after the fault, 20 ft. 



b. The micaceous sandstone, thin and false-bedded, with well marked 

 cleavage, 16 ft. 



c. Foetid pale brown, calcareous sandstone, viz. false-bedded ; no fossils ; 

 dips. E. S. E. 30° ix ft. 



d. Shales; no fossils, 1 f 00 t. 



e. Limestone, compact and dark grey, and weathering brown. It is much 

 shivered, and is divided by innumerable white lines crossing each other. No 

 fossils except what appear to be worm-burrows filled with sandy ochre, 15 ft. 



/. Very argillaceous limestone of a pale blue colour, with patches of a dirty 

 yellow or pale brown colour, 3 ft. 



29. I consider that these beds are the top of the Weean division of 

 the carboniferous limestone of the Himalaya, as the following beds 

 show a very great difference in their fauna, which is nearly entirely 

 confined to gasteropods and corals, the gasteropods presenting a great 

 variety of shape and size. The corals of the CyatJiojiItyUidce are 

 abundant and of considerable dimensions. The crinoid stems, some of 

 them minute and starred, continue to be seen everywhere. The beds 

 characterized by gasteropods and corals form the Kothair bed, which 

 we shall see better developed elsewhere. 



Continuing our section, we have therefore, resting on the argilla- 

 ceous limestone, the following layers : 



g. Limestone, fine grained, blue, compact and argillaceous, with patches of 

 dirty yellow. It contains many fragments of fossils, nearly entirely gasteropods. 



Some of these are two inches in length. Starry rings of crinoid stems 

 abundant. The limestone becomes gradually of a richer blue colour, some 

 portions being indeed light blue ; it weathers rugose like frosted glass. The 

 upper part contains no gasteropods, but fossil roots and rootlets the size of 

 the finger. It is about 25 feet thick, 25 ft. 



This is all we see here of the Kothair bed, as a fault running N. S. 

 brings up again the .Weean bed ; but this patch of the Kothair 

 is interesting, as showing its relation to the Weean bed, a relation 

 which I have not been able to trace so well anywhere else. The 

 Weean and Kothair beds are quite conformable. 



On the other side of the fault we find : 



a. A limestone, bluish-grey and compact ; weathering sandy and dull 

 grey. It is divided in layers by several sandy partings. It contains only 

 a few encrinite stems and dotted white patches which are probably decomposed 

 fossils. It is shivered and traversed by innumerable white lines, 20 ft.
