LOWER TRANSITION ROCKS. 93 



The mass of the Sandur hills is arranged in four divisions, two of 



Sub-division of the which lie north-west of the Narihalla river and 

 Sandur hills. two ± the south-east. For convenience, I must 



give separate names to the four parts, which the natives have omitted 

 to do, though many isolated spurs and ridges have separate names. 

 The division north-west of Sandur had best be called the Raman Drug 



The Raman Drue division, " a", from the curious old hill fort which 

 division "a". crowns the central part of the ridge and close 



to which lies the modern military sanitarium of that name. The 



The Ramgol division north-eastern division may be called the Ram- 

 " b "• gol division, " b", from a very beautiful ravine of 



that name which lies about the centre of the ridge. A much lower 

 parallel ridge lies outside the Ramgol ridge, but merges into the main 

 ridge at its northern end. 



The south-eastern division lies south of the Narihalla, and is 



The Donimale- divi- separated by the Mudkalpenta valley from the

of the valley from the south-western division. The former may conveni- 

 ently be called the Donimale division, " c ", and the latter the Kuma'ra- 



The Kumaraswami swami plateau, " d'\ (or division). The Devadara 

 division, "d ". ridge is a northerly offshoot of the latter plateau 



and should be reckoned to belong to it, as it is part of the western 

 side of the great synclinal. 



The Kumaraswami plateau is so called after the famous temple of 

 that name which stands near the western end of the plateau. 



The Donimale has a lofty and conspicuous spur to the east, which 

 is called the Vala Bhadra Konda, and which unites with the Donimale 

 plateau some 5 miles to the south.
