Jurassic and the nummulite-bearing limestones, a mass of light or dark-colored 
limestones without fossils, which perhaps belongs to the cretaceous period. 
The fragmentary Ammonites found in a limestone rib southward of Huveli- 
yan (see ante p. 121) on the opposite side of the Dore valley from the cretaceous 
band of Sii’ban, occurred in limestones with somewhat the aspect of those of 
the cretaceous zone; but it is not even known whether the sjiecimens can be 
determined. 
7. Ntmimulitic .—The nummulitic eocene limestones of these hills presents 
no peculiarity beyond the general featm-es described in former papers (Rec. 
Geol. Surv. Ind., vol. VI, pt. 3, vol. VII, pt. 2, vol. X, pt. 3 ; Q. Jnl. Geol. Soc., 
London, vol. XXX, p. 61, vol. XXXIV, p. 347). 
It occurs very extensively, yet its thickness, which must be very great, is 
difficult to determine on account of the frequent faults and the disturbance of 
the beds. One seetion from Murreo northwards would indicate a greater 
thickness than 2,700 feet for what is but a part of the series ; and from 3,000 to 
5,000 feet may be a probable, though necessarily a very conjectui-al, estimate for 
the whole. 
These dark gray eocene limestones of the outer Himalayan region, alternat¬ 
ing frequently in some places with olive shales which are almost entirely absent 
in others, and containing sometimes an abundance of small Toraminifera, some¬ 
times scarcely a fossil distinguishable with a lens, are in a manner peculiar 
to the northern regions of the Punjab, as has been already pointed out (1. c., 
above). There seems to be a possibility that in the higher portion of the hills, 
traversed by the upper Abbottabad and Muiree road, the group includes in its 
lower part dark red and blackish gypseous shales and sandstones of the aspect 
of those found in the base of the succeeding tertiary sandstone series, but the 
point is obscure. There is also a considerable apjjearance of transition from the 
upper or outermost beds of the Hazara hill-nummulitic rocks into the upper 
nummulitic zone near Murree, which is transitional with the lower tertiary sand¬ 
stones and clays just mentioned. The apparent passage is dcducible from the 
arrangement of the rocks in the region of the abnormal contact between the Hill 
limestones and outer tertiary zone, and therefore less trustworthy than it might 
be ; still such apj)earances, even in disturbed localities, should not be overlooked 
(see Section Xo. 5 annexed). 
The upper nummulitic beds of this district, scarcely appear within the hilly 
ti-act from Mochpura mountains westward in other than doubtful exposures. 
Some of its beds are faulted into junction with the hill-nummulitic and Jurassic 
rocks between Shaladitta and Garm Thun, on the road from Rawalpindi to 
Khanpur; and the faulted mass of red rocks with gypsum, in the Haro Kas 
below Dungagali (north of Murree), may either belong to this grouji or be 
intercalated, as just now mentioned, at a much lower position with the eocene 
limestones. 
Another more extensive exposure of red argillaceous and arenaceous rocks 
was met with this season capping the Lachikhun mountain, in the range over¬ 
looking the Nainsfik at Ghari Habibula from the east. Lithologically these 
might represent a variety of the lower tertiary sandstones (Murree beds), but
