66 CRETACEOUS ROCKS OF S. INDIA.. [PaRT II. § 1. 



The spectator is supposed to be looking Eastward. The rising ground 



on which the light falls in the mid distance is capped with coral limestone, 



the bare rocky masses of which are also seen stretching along the ridge to 



the Southward. At its base the dark bank of the little nullah is formed 



by the boulder-bed, of which 8 or 10 feet are exposed, and although so 



close to the limestone, containing not a single fragment of any other rock 



than gneiss. In front of the ridge, and also intersected by the nullah, are 



seen the flaggy Umestones and shales atthebaseof tlieTrichinopoly group, 



resting at an angle of about 30° on the denuded face of the boulder-bed in 



the nullah section, and on that of the coral limestone a few yards further 



South. This high dip is, however, quite local, and at the distance of a few 



yards it diminishes to not more than 5° or 6°. Almost at the point, where 



these beds are intersected by the nullah, they turn round sharply to the 



Westward, or towards the spectator, so that their strike becomes coincident 



with the course of the gully, in the bank of which their out-crop is seen to 



the right of the sketch, while to the left fore-ground are the coarse fossilife- 



rous grits, which I have referred to the Ootatoor Group (page 47), and which 



rest on, and are in part intercalated with the boulder-bed, and dip gently 



towards the spectator, or at right angles to the overlying Trichinopoly beds. 



Following the out-crop of the Trichinopoly beds to the North-west, 



another patch of the coral limestone is met with 

 Between CiiUygoody 



and Kim-acoopay. at the South of the nullah that drains the Cully- 



goody valley. It is low and flat, and resembles, in all respects, the lime- 

 stone of the lower part of the Cullygoody ridge, the streaked coralliferous 

 rock being common both in situ and in the boulders of the rock, which 

 aie enclosed in the overlying Trichinoj)oly conglomerates. It is, in fact, 

 the base of a ridge, the upper part of which has probably been denuded. 

 Some limestone is found to the North of the stream, both resting on the 

 boulder-bed, and, as already mentioned, on the 

 gneiss, to the East of Malarasure, but only in small 

 quantity. To return to Cullygoody : the Southern edge of the Cullygoody
