is traversed by the upper portion of the Machna 



river, a tributary of the Tawa. The range of low trap hills already 

 mentioned bound this valley to the south, and form, in fact, the parting 

 ridge between its drainage and that of the Taptee. 



Along this low scarp the beds of trap are, in part, horizontal, in 



Trap hills south of ^^^^^ places they have a very low southern dip.

where this is seen is east of Bayawadij beyond 



that to the eastward the intertrappean band probably thins out. An 

 unfossiliferous calcareous mass was met with near Khappa, still further 

 east, but it was at a higher level, and, if belonging to an intertrappean 

 bed, must have been part of a distinct stratum from that seen at 

 Bayawadi. About Sohagpoor and further east no trace of any intertrap- 

 pean bed could be found. 



The fossiliferous bed is best exposed near the village of Loharee, and on 

 the sides of the road from Baitool to Dholun and Mausood. At the top 

 of the Ghat, upon this road, there are many scattered fragments con- 

 taining shells, wood, cyprides, fee, but no bed is seen in place. On the 

 face of the hill, however, a few feet below the top, there is a bed scarcely 

 distinguishable in mineral character from the trap, from the debris 

 of which it appears to have been composed, but abounding in fossils, 

 especially Thjm Frinsepii, Lymnea, Paludina, Valvata, and plants. 

 Lower down there is a thin band of very silicious rock, resembling
