Again, in the Byrenconda range the Cumbum series is subjacent to

masses of that part of the Nullamullays, as in 
the Nemillygoondum region and again on the Nundycunnama, and further 
south still in the mountains above Howhoblum Pagoda. 
In the northern part of the field of these slates, they roll down 
In the Kistnah Null. Under the quartzites of Waumyconda, the eastern 
anlaya part of the Kistnah hills, and possibly under- 
neath the strata of Irlaconda. This part of the country is, however, 
full of obscurity, for the intercalated bands of quartzite are numerous 
and not traceable continuously for any distance; and it is thus diffi- 
cult to say whether all the bands in the Waumyconda, or Innaparaty- 
conda, &c., belong to the Cumbums or not. From what has been 
seen of the rocks, it would seem as if the higher quartzites of Waumy- 
conda were representative of those of the Yellaconda, and the lower 
bands were the intermediates of the Budvail valleys and of the higher 
parts of the Lunkamulla. Under this view, the uppermost quartzites 
of the Kistnah Nullamullays would answer to the Yellacondas, while the 
lower series of Irlaconda might be representative of the Kullsapad 
quartzites; the Innaparatyconda quartzites being the same as these last, 
and let into their peculiar position in the range by faulting. 
There is no indication of unconformity between the Yellaconda 
beds and the Budvail slates; nor is there any 
` [Indications of uncon- 
formity in the Kistnah between the uppermost Kistnah beds and the 
rs slates beneath. But there are traces of such a 
break in the Waumyconda range of hills; the quartzites and intermediate 
red sandy slates of the higher. parts seem to be a thinning out of the 
Kistnah beds, and thus the bottom of these, or the quartzites immediately 
north of Innaparatyconda ridge, are unconformable on the Cumbums of 
the Dorenall or Muntaral pass.
