in the Wastarwan and Zebanwan, and both ash and slate are occa- 
sionally cellular or amygdaloidal. There is neither limestone, granite 
or porphyry among Captain MacQueen’s specimens, and I believe 
therefore that the two last rocks at any rate do not occur in these 
mountains, as pieces of granite and porphyry generally attract the 
attention amongst the dull ash-rocks and would not have failed to form 
part of the collection, if they had existed. It is very possible that 
remains of beds of limestone are to be found amongst the spurs of 
the hills. 
On the north of the Woolar Lake, many mountains of no great 
height form a sort of amphitheatre. They are nearly entirely 
composed of amygdaloidal greenstone, ash and slate interbedded, 
but near the village of Bundipoor, about two miles east of the 
road, some beds of limestone are seen. Mr. Drew has kindly sent 
me some specimens of it that are a flesh-coloured, sometimes 
greenish, very arenaceous and argillaceous. They are not at all 
crystalline, but contain an enormous number of encrinite stems 
transformed into spar with a cleavage oblique to the axis of the 
stem, so that when the section of a stem weathers, it appears striated 
across. This crystallisation has destroyed the structure of the stem, 
but the central canal is seen in a few specimens. We have seen 
this rock well developed at Manus Bal, towards the end of our section, 
where the beds of flesh-coloured limestone alternate with grey sandy 
limestone containing crinoid-stems transformed into a spar as black 
as coal. (See 35 of the section of Manus Bal). The limestone of 
Bundipoor is therefore Weean limestone. 
On the west shore of the Woolar lake, the Taltiloo and the 
Chralkoot present perpendicular cliffs of volcanic rocks descend- 
ing into the water. From a boat on the lake, it is easy to 
observe the usual thick and confusely bedded masses of greenstone 
and amygdaloid forming the centre of these hills, and the more sloping 
and regularly stratified layers of ash, laterite, agglomerate and 
slate well developed, in the long spurs which descend on all sides, 
The whole mass of hills appears to be made of volcanic rocks, and the 
lowest spurs which approach the shore of the lake present no fossilifer- 
ous beds. Of the higher peaks, the Kahoota, Manganwar and Sheri 
Bal, I know nothing, but there can hardly be a doubt, however, of 
their being volcanic in their formation,
