11. Tlie " Soutli Peak Station" mountain between the two upper brandies of the Dudh- 



Gunga river. 



12. The plateau ridge between the valleys of the Dudh-Gunga and Bhogavatti rivers, 



13. The ridge north of the Bhogavatti valley. 



Far away from the ghats but connected with the eastward exten- 

 sion of the great Bhudhargarh ridge are 

 14 The Wallabgarh outlier and 



15. The Baged Gudda outliers, two in number ; on the eastern one a trigonometrical 



station 2,667' high. 



16. The group of outliers west and south-west of Gokak, two of which are overlaps 



on to the Kaladgi quartzites. 



17. The Paizargal'h group of four small outliers, with a fifth forming' the summit of 



Hoolee Gurkeit hill, three miles to the east. 



18. Arlehatti outlier, four miles west of Pachapur (Padshapoor), rests directly on the 



quartzites, as do also in part 



19. The Ramdurg outliers, four in number, lying 10 miles north of Belgaum. The 



most south-westerly of these rests partly on the trap, partly on the quartzites. 



20. Yellurgarh, seven miles south of Belgaum, shows the last of the summit bed out- 



liers which there rests on trap. The summit is 3,365' high. 



There are several other outlying patches of similar ferrugino-aro-il- 

 laceous rocks in the more eastern parts of the trap area, but they are too 

 distant to be safely correlated with the summit bed. 



Numerous though the outliers of the summit bed are, they yet 



present very few satisfactory sections; not one in- 

 Sections mostly obscure. 



, deed could be considered really good for the pur- 

 pose of studying the origin of this peculiar rock and its relation to the 

 underlying trap-flows. Owing to the superior hardness of the highly 

 ferruginous summit bed and the more rapid weathering away of the 

 underlying beds, the surface of the latter is very generally covered by 

 talus or by great fallen masses of the upper beds. In other sections a 

 quasi-stalactitic ferruginous rain-wash frequently renders the surface 

 appearance of inaccessible cliffs doubtful. The presence of delicate grey, 

 orange, pale-pink, and flesh-colored lichens in very large numbers in 

 many cases changes the colors of the scarp faces very greatly, so that it 

 is only on close inspection that the true colors can be made out.
