Cardium (Killanum?) an litoceramus, 2 Motliolce, a Hemicardium and 



other bivalves. These are mostly casts^ as are also a few Gastropoda 



which accompany them' Besides the Hemiaster, some other Echinoder- 



mata are founds amongst them a Cidaris. 



This fossiliferous bed^ just north of Cheerakhan, was 8 or 10 feet 



thick^ and rested upon 15 or 20 feet of unfossili- 

 Section at Clieerakhan. 



ferous nodular limestone of a type much more 



extensively distributed than is the fossiliferous bed. 



Just south of Cheerakhan, the trap rests immediately upon sand- 

 stone, and here, as at Dussai, much fossil wood 

 South of Cheerakhan. . . 



converted into a jaspery hornstone is associated 



with the latter. It is not clear that this sandstone is of cretaceous age. 

 It might belong to the traps. 



In the upper Maan valley, north of Cheerakhan, there is no sand- 



Kocks north of Chee- ^*°^® ^1* limestone, and the traps rest directly 

 rakhan. upon metamorphic rocks. As will be seen, this is 



usually the case to the north. 



The surface is composed of metamorphics or cretaceous beds as far 

 as Goorsul, on a tributary of the Maan river, 5 or 6 



IiTegular junction of 



traps and cretaceous beds miles north-wcst of Cheerakhan. Here some good 



near Goorsul. . . o ji • 



instances are seen oi the irregular manner in 

 which the traps rest upon the cretaceous beds. Close to Goorsul, meta- 

 morphic rocks occur in the stream ; sandstone and limestone, the latter, 

 as usual, above the former, form high terrace-like banks. Eut just north 

 of the road from Boreghat to Goorsul, and upon the banks of the 

 stream, trap rests directly upon metamorphics along the north bank of a 

 small ravine, while on the south bank, within a few yards, is a hill 

 of limestone. Again, in the flat ground of the valley close to Goorsul, 

 a small hill of trap stands by itself, resting on the metamorphics, 

 while the hills on each side of the valley are of sandstone and limestone,
