much less. All the upper portion of the group consists of massive sandstone beds, which 
are generally quite unfossiliferous, but occasionally contain bands of clay and shale with 
fragmentary plant remains. Towards the base of the sandstone, beds of limestone with the 
characteristic Nummulites are occasionally interstratified, sometimes five hundred feet, or 
even more, above the principal limestone beds at the base of the group ; thus clearly showing 
that the limestones with Nummulites garansensis, &c., belong to the same sub-division of 
the tertiary series as the sandstones. 
In many places, especially towards the base, very ferruginous hands are interstratified 
with the sandstones; and south of 'Sehwan, on the west side of the Bhagotoro range, where 
the thickness of the whole group is much less than in the Khirthar range, the upper portion 
consists of ironstone, ferruginous sandstones, and brightly coloured clays, purple, brown, and 
white. On the Khirthar range, however, almost the whole group, except at the base, is 
composed of massive beds of brown sandstone. Throughout the area examined, the upper 
nummulities rest conformably upon the lower, but there is a complete break in mineral 
character, and the fossils are different, the two characteristic species of Nummulite, for 
instance, being distinct from any hitherto found in the Khirthar group. 
The whole thickness of the Nari group on the Khirthar range can scarcely be less than 
five thousand feet. 
In some places the limestones at the base of the Nari group contain a large number of 
Mollusca and Echinodermata. The following have been identified; a large proportion are 
from Bhagotoro, south of Sehwan

* O. papyracea (BoubSe) : see Geological Magazine, November 1S75, p. 535. As before remarked, for conveni¬ 
ence sake, D'Arehiac and Haime's specific names are preserved throughout this paper. I believe this rhizopod to 
be correctly identified, but at the same time it appears to me to be the species identified by Dr. Carter with 
O. Mantelli.— Journal, Bombay Branch Royal Asiatic Society, vi, pp. 79,82, &c, &c.
