DIENER : TRIAS OF THE HIMALAYAS. 
RhyncJionella cf. trinodosi'Bittn.,Rh. cf. mutdbilis Stol. and Spiriferina 
Stracheyi Salt, have been collected by C. S. Middlemiss. 
c. The Muschelkalk of Eastern Johar. 
The development of the Muschelkalk in Eastern Johar agrees, as far 
as known, with that observed in Spiti and Painkhanda. The fossils, 
which have been collected from the ridge between the Dharma and 
Lissar valleys, are imbedded in a dark shaly limestone. Among the 
Cephalopoda the overwhelming majority are identical with species 
from the Shalshal cliff. The following species belong to the Upper 
Muschelkalk :— 
Grypocems sp. ind. ex. aff. Palladii Mojs. 
Ceratites Thuilleri 0pp. 
,, {Hollandites) Havana Dien. 
„ Airavata Dien. 
,, ,, Dungara Dien. 
Beyrichites cf. Rudra Dien. 
Pseudodanuhites cf. Dritarashtra Dien. 
Acrochordiceras Balarama Dien. 
cf. Carolince Mojs. 
„ sp. ind. aff. pusterico Mojs. 
Gymnites Sankara Dien. 
„ Jollyanus 0pp. 
The presence of the zone of Spiriferina Stracheyi is indicated by this 
species and by Dielasma himalayanum Bittn. 
d. The Musclielkalk of Byans. 
A. V. Krafft has drawn the attention of Indian geologists to the re- 
markable uniformity of the Muschelkalk in Spiti, Garhwal and Kumaon, 
a uniformity which goes so far that almost every single bed found in 
the one area can be recognised in the other. It seems, however, that a 
change takes place towards the east, for in Byans, in the north-eastern 
corner of Kumaon, near the boundary of Nepal, the Muschelkalk is 
developed in the facies of light grey limestone, without any trace of
