At Imam Mir A'chmet, between BA slit and Faylaun (Fabliau) tb
neighbouring range is composed as follows;— ' e
(1) Hard, yellow, eompaet, crystalline limestone, probably belono-in ff to
tbe nummnhtic limestone. In tbe lowest beds it becomes cream
coloured, and passes into—
(2) Hard, reddisb, grey or cream-coloured lithographic limestone very
compact, but splitting into thin layers, with abundant specimens of
ammonites (crushed), gryphata, and
Interstratified with this limestone are numerous tabular layers of a black
siliceous substance giving out a remarkably strong odour of bitumen
when struck.
(3) Highly crystalline, blue, fcetid limestone.
c ^ ^ Iff between the plains of Sar Ab-f-Sfr and Faylaun (Section
fig. 7), the blue limestone ( 5 ) is much contorted and surrounded by the
yellow ( 4 )^ wliicn appears to be conformably deposited upon it.
In this neighbourhood the yellow limestone constitutes the summits of
many isolated tabular forts, and rests on a base of blue limestone. The
notorious Kal a Sand is a fine example of this.

The only instance in which undoubted deposits of this age were observed
by me was on the east side of the Kub-i-Kellar range, between Nauo-dn

Bakhtiari Mountains. This range is composed of the ambiguous, altered,
blue limestone; but I had only an opportunity of examining an insignificant
portion of it, overlooking the plain of Cheragbur, where I gained no in-
formation whatever. Just before entering the plain from the west, however,
I stumbled upon two or three blocks of highly crystalline grey limestone;
weathering rusty-yellow, filled with a species of ort/tis, which Mr J Morris
considers as a form intermediate between tbe Devonian and Silurian species,
tho durmg a hasty journey prevented my giving the locality
the attention it deserve..; but I was informed by the natives that at the
summit of the range are great quantities of similar fossils.
