inspection. The agreement with the Alpine Hallstatt Hmestone is 
lithological as well as faunistic. The faunistic difference between the 
carnic beds of the Himalayan and Tibetan facies, which are not more 
than a few miles apart, is much more conspicuous than between the 
latter and the Hallstatt limestone of the Roethelstein. 
Fifteen species are identical, or probably identical, with Alpine forms 
and nineteen altogether with forms which have their habitat in the 
Mediterranean province, including four species, which are known to us 
from Sicily but not from the Eastern Alps. This is an unusually large 
percentage of Mediterranean types in an Indian fauna, and is only 
exceeded by the Mediterranean affinities of the Lower Liassic fauna of 
the exotic blocks Nos. 16 and 17 south of ths Kiogarh high plateau. 
Particularly striking is the preponderance of the genera Arcestes 
and Cladiscites in number of individuals in the Tibetan facies, whereas 
those two genera are of rare occurrence in the carnic stage of the 
main Triassic region of the Himalayas. In this character the carnic 
fauna of the Tibetan facies agrees exactly with that of the Alpine 
Hallstatt limestone.

To the east of Chitichun No. 1 an exotic block was noticed by 
Diener {Enjebnisse, etc., i.e., p. 602), which is remarkable on account 
of its regular conical shape. It is built up of a yellowish-grey limestone, 
recalling the higher beds of the Upper Triassic Dachsteinkalk of the 
Shalshal cliff section. 
In the region of exotic blocks of Malla Johar the divide between 
Kiogarh No. I and No. V has been described by A. v. Krafft as consist- 
ing of a great mass of grey, dolomitic limestone, without any fossils, 
but resembling the upper noric or rhaetic Dachsteinkalk of the main 
region. " Nevertheless there is no complete lithological identity be 
tween the two, the Tibetan grey limestone being massive throughout, 
while the Himalayan Dachsteinkalk is well bedded. "i 
/. Summary. 
All Triassic beds represented in the exotic blocks of the Chitichun 
region and of Malla Johar belong to a facies different from that of the
