2G On the Sul- Himalayan rocks. No. 1, 
'i'he upper sub-division of the Nummulitics is best seen near Suba- 
thoo, and gives three sub-groups in descending order — • 
1st. — Sandy — bard sandstones largely predominate ; well exposed 
in Itussowli bill. In this group (at Ivussowli and elsewhere) some 
well-preserved leaves and stems of trees, and other remains of terres- 
trial vegetation have been found. 
2nd. — Sandy-argillaceous — lumpy sandy red clays. These are 
characteristically seen in flanks of Dugshai hill. 
3rd. — Calcareo-argillaceous — well seen near Subathoo. These are all 
connected by conformity in stratification, and by transition in mineral 
character, and form one continuous sequence. They may be called 
the Subathoo group. 
In rocks so contorted it is difficult to estimate thickness, but 1800 
to 2000 feet may be given as the minimum. 
All fossils hitherto procured, have been from the lower half of this 
series, as seen near Subathoo. 
The beds of this upper or Subathoo group are often found folded 
into the contortions of the Krol group and the subjacent slates — 
(Krol and Boj mountains, &c.) 
This Subathoo group is entirely distinct, as shewn, from the band 
of limestones and slaty clays long known to extend along the South- 
ern border of the Western Himalayas. It does not appear to extend 
to the East of the Jumna : at least no trace of it is seen between the 
Jumna and Nainee Tal. 
The separation we have made here from stratigrapliical considerations 
was in a manner anticipated by D’Archiac from a consideration of the 
fossil evidence alone ; at least he pointed out the entire distinctness of 
the organic remains of Subathoo as compared with those of the Punjab, 
of Scinde, of Beloochistan, and of Cutcli (p. 175.) But in tbe concluding 
section of this description (p. 179) where reasoning on the very uncer- 
tain observations of others, he is far from correct in stating that no 
appreciable unconformity could be observed between the two, or indeed 
between the Nummulitic strata generally and the overlying Siwalik 
series. 
The evidence for supposing the Krol group, as given above, to be 
also of Nummulitic age, is not perfectly conclusive. Mr. A. Scldagin- 
tweit has announced the discovery of Foraminifera in the neighbour-
