part 1 .] Blavford: Great Indian Desert between Sind and Edjputand. 19 
beds is not seen, but the lowest strata exposed at Kita, 15 miles from Jesalmir. on the road 
to Balmir, are fine white beds, soft, argillaceous, and slightly micaceous, and stained purple, 
lilac and scarlet in places. Some of these beds so closely resemble the variegated sandstones 
of Balmir that it is probable they are of the same age, and their much greater softness may 
be due to the smaller amount of disturbance they have undergone. Precisely similar soft 
white sandstones are found at Lathi, 40 miles east-hy-north from Jesalmil - , and are doubtless 
on the same horizon as those of Ivita: at both places fragmentary plant remains are common, 
hut nothing recognizable could he found except some dicotyledonous fossil wood, which occurs 
at.Lathi. 
These rocks resemble the TJ'mia beds of Cutch, and they are very similar to some 
Gondwana rocks, especially portions of the Kamthi and Mahadeva groups. 
5. Jesalmir limestones. —Above the beds last mentioned are the Jurassic limestones and 
sandstones of Jesalmir. These consist of sandstones with thick bands of compact, buff and 
light-brown limestones, one of the most beautiful building-stones in India, and of which 
much use might he made if it were more accessible. The sandstones vary much, being grey, 
brown and blackish (ferruginous), sometimes calcareous, and occasionally iuterstratified with 
hands of conglomerate, containing pebbles of quartzite, red jasper, and ferruginous sand¬ 
stone, the last of which looks as if derived from the underlying group. Some other forms 
of limestone occur, and in one place a grey rock abounding in shells is found. 
The limestones contain numerous fossils. Specimens of Ammonites ( Stephanoceras) 
fissiis, Sow., were obtained from the natives at Jesalmir, but the exact locality could not be 
determined; there can be little doubt, however, of its being in the neighbourhood of the 
town. I found the following species in the limestone scarps ; for the determination of several 
of them I am indebted to Dr. Peistmautel: —
