UPPER GONDWANA SERIES, 53 



probably not more than, if as much as, 60 feet. Resting on the surface of 



the sandstones are concretionary fragments of purple clayey sandstone, 



containing plant remains of Rajmahal age, now worn into pebbles, and 



belonging to the lateritic gravels. Further north, 3 or 4 miles east 



of Chinna Latarapy, similar washed-up purple plant sandstones form a 



considerable proportion of the lateritic gravel resting on the gneiss. From 



similar purple grit and hsematitic sandstone pebbles in the laterite gravel, 



unquestionable Rajmahal plant remains were obtained to the south-east of 



Razpalem, 3 or 4 miles north of the Peddavaram bluff just described. 



Among the plant remains here found was part of a frond of Ptilopliyllwm 



{PaltBozamia) . 



To the northward of the Chinna Latarapy patch of Rajmahals are 



several sections of plant beds, chiefly sandstone, to 

 Mogallur sections. , - 



be seen in the Mogallur nulla, and in the bed of 



the Man-eru east of Mogallur. In the latter case, the friable brown 



micaceous sandstone yielded parts of broad Ptilophyllum fronds. This 



plant bed is overlaid apparently by the various sandstone and shale beds 



seen in the principal section in the Mogallur nulla which present the 



following series in descending order, the beds having a general dip of 



from 7° to 10° to the south-south-east : — 



Shale, sandy, ferruginous
