MA HAN SECTIOXS. 63 



sandstone beds of the Paupliica nullah contain the following- Barakar 

 forms : — 



Glossopteris damudica, Fstm. 



„ indica. 



„ communis. 



Naeggerathiopsis hislopi, Bunb. 



The shales and clays dipping- below the scarp of the Tamor and Bendo 



hills contain Glossopteris angustifolia, Bgt., Fertebraria indica, Royle 



(branched form), and may probably belong- to the Ranigauj series, which 



they resemble in some respects. Near Namadhakai I obtained a nearly 



complete succession of the Gondwana series : — 



I. — Mahadevas of the Kathota hill. 



ll.—Barahar type resting on the Talchirs, but nothing further was exposed 

 between these and the — 



III. — TalcMr silts rest there on metamorphics (granite), containing many 

 boulders of red Vindhyan quartzites. They are well seen in all the 

 gullies coming down from the Kathota hill. 



The great trap-sheet already mentioned has chiefly forced its way 

 between beds of the Panchets and the Mahadevas, so that in nearly all 

 the sections hereabouts, trap is met with in that horizon, thouo>h not 

 always seen in situ. , 



C. — Mahan River Sections. 

 A very good section through nearly all beds of the Gondwanas is 

 obtained between the Mahadevas of the Tamor scarp and the metamorphic 

 series south of the Mahan river, fig. 3, Plate 5. I found in descending 

 order : 



6. The Mahadeva sandstones and grits form the wall-like escarpments of the 

 Tamor and Dokrichana hills, which rise up to 2,758 feet, and which I have 

 already described in my general chapter on Mahadevas, p. 19. 



• Namadhaka is a favourite encamping ground of the Gaewallas (herdsmen) of Sing, 

 rowli, who take their cattle to the Sirguja jungles during the dry season for grazing pur- 

 poses ; it is south of Dand Karua and north-west of Pandari, just below the Mahadeva 

 scarp, which stretches in a nearly north-south direction from near Pakni to Daud Karua, 

 aua which is called the Kathotha hills on the large survey maps.
