There is only one single species, Nannites hindostanus Dien., which 
connects the faunae of the Hedenstroemia beds and of the lower divi- 
sion of the Lower Trias. Otherwise the two are separated much more 
distinctly than those of the Meekoceras and Ophiceras beds. 
The presence of the first true Ceratites, of numerous species of 
Flemingites, of Hedenstroemia with sutures far more advanced than 
in H. lilangensis, of species of Aspidites and Koninckites of large size 
and with complicated sutures, imparts to the fauna of the Hedenstroe- 
mia beds its pecuhar aspect. 
On the top of the Hedenstroemia beds there follow lithologically 
similar beds of shales and limestones having a thickness of about 6 feet. 
Two fossiliferous horizons were discovered in those beds by H. Hay den. 
The lower horizon has yielded large numbers of bivalves, chiefly 
Pseudomonotis himaica Bittn. and Ps. decidens Bittn. The upper horizon 
with Rhynchonella Griesbachi Bittn., and Rh. himaica Bittn. , corresponds 
to a layer, which in Painkhanda has been included in the lower 
Muschelkalk by Griesbach and Diener. 
b. Painkhanda. 
Our knowledge of the development of the Lower Trias in Painkhanda 
has been derived chiefly from the examination of the classical section 
of the Shalshal clifi near Rimkin Paiar by C. L. Griesbach, C. Diener and 
F. Noetling. 
In 1879 the Otoceras fauna was discovered by C. L. Griesbach on the 
top of the Permian Productus shales. The bed containing this fauna was
