but few are of any importance topographically, except the two groups of 

 granitic hills lying north and north-east of Ling

Sugur on the south bank or the Krishna, the one 



between Jal Drug and Jalihal, the other lying immediately east of Jalihal, 



and Gallag (Gullug) . Another irregular group of schistose hills which 



lies south of these two groups may be conveniently 



Kautala Hills. o r j j 



called the Kautala Hills from the large village of 



that name'^ which stands about the middle of their course. At the ex- 

 treme eastern end of the area are the granitoid hills of Raichur. The last 

 orographical feature in the Raichur Doab is a narrow ridge running north- 

 westward from near Tawurugiri to Kandagal in Kaladgi district. Beyond 

 this the beds of haematite schist, which form this remarkable ridge, 

 have been traced for nearly ten miles, and there can be little doubt that 

 ^ Hunugunda hematite ^^^7 reappear in the Hunugunda Hill and also 

 "^S®" further west in the low hsematitic ridges which 



may be followed in a north-westerly direction till they disappear under 

 the quartzites of the Kaladgi series at Yerkal, at the picturesque gorge 

 of the Ghatprabha River. 



No connection can be traced between these various hill groups of 

 the Doab and the Ghat range, except as far as extensions of the various 

 watersheds may be concerned, for there can be no doubt that many of 

 them had existed as hills at ages long prior to the out-pouring of the 

 Deccan trap flows to which the ghats owe their present importance in 

 the region under consideration. 



On the left or northern bank of the Krishna, nothing worthy of the 

 name of hills occurs till the neighbourhood of Cheemulga is reached. 

 There, and a few miles to the east at Nirgundi (Neergoondee), are some 

 low quartzite and conglomerate hills. 



A little further east the terrace character spoken of above (page 4) 

 first appears, and continues along, or very near to, the boundary of the
