north-west of Kalamulla. This also is a very small inlier of Rajmahal 

 beds among lateritie sands. 



We now come to the Chautapalem patch, the largest of the Kandu- 



kur group, but which despite its size offers but

little of interest, as it contains not a single good or 



instructive section, only a few poor well-sections, and no good fossils 



were obtained from the soft, often shaly, drab or brown sandstones they 



expose. 



The Ponnalur patch, which is only separated from the foregoing by 



about a mile of overlying lateritie sands, shows soft

shales and shaly friable buffy-brown sandstones 



underlying the lateritie beds at its northern extremity, close to the 



village after which it is called. Soft drab sandy beds are exposed in 



a well-section about a mile to the south-west. Plant remains are scarce 



and very fragmentary, but enough were found to determine the age of 



the beds beyond doubt. 



Between 6 or 7 miles to the eastward lies the village of Kovur, 



which stands on a narrow strip of Rajmahal 

 Kovur section. 



rocks lying between the northern boundary of 



the Kandukur laterite area, and the alluvium of the Paleru, and 



extending rather more than 4 miles from east to west. A few good 



well-sections, south of, and close to, Kovur village, give some insight 



into the nature of the plant beds here occurring. The rock exposed is 



drab micaceous sandstone, shaly in part, having a north-easterly dip. 



Some of the more shaly laminae, as exposed in the waste heaps of material 



dug out in sinking the wells, show recognisable plant remains, though but 



small and fragmentary parts of the plants are preserved. 



Among the specimens collected were fragments of three species of 



Ptilophyllum, and with them impressions of minute 

 Fossiliferous shales. 



bivalve shells which were remitted to Calcutta 



for determination. The eastern part of the patch is greatly obscured by 



a remarkable bed of massive kankar-like limestone of undetermined age, 



which is especially developed at Kunda- Kandukur (Conda Cundacoor).
