GENERAL CHARACTERS. 143 



far identified the following three species with forms described from 

 the Himalayan " Daonella beds" : — 



Ciadiscites subaratus, v Mojs. 

 Phylloceras ebneri „ „ 

 Juvavites {griesbachites) medley anus > 



The commonest genus of the fauna is Ciadiscites, a species belong- 

 ing to the group of Ciadiscites tomatus being the leading fossil. 



Other genera are : Tropites, Arcestes, Placites, Jovites, Nautilus, 

 etc. Of the rare Tropites, species resembling T. subbullatus, T. 

 acutangulus, T. barthi, and T. spinosus, v. Mojs., occur. 

 This fauna also awaits detailed examination. 



There can be no doubt that it represents the Tropites horizon of 

 the carnic stage, being equivalent to the " Subbullatus beds " of the 

 Alps and the Tropites limestone of Spiti and Byans. 



The loose block with Jovites n. f. ind. ex. aff. J. bosncnsis found 

 by Mr. Griesbach near Talla Sar.gcha E. G., belongs to this horizon, 

 this species being also present in my collections from E. B. 2. 

 Carnic blocks are not recorded from the Chirchun area. 

 6. Dachsteinkalk (?) Exotic block 8 (pi. 7) and Kiogarh high pla- 

 teau (plates 2 and 3). The predominant rock of the exotic masses 

 is a light grey, dolomitic massive limestone. Its main distribution is 

 in the mountains between the Balchdhura and Kiogarh-Chaldu passes 

 (Kiogarh high plateau), but blocks of light grey, dolomitic limestone 

 were also found elsewhere. 



Unfortunately not even a trace of a fossil was observed, but it is 

 probable that the limestones represent chiefly the Dachsteinkalk. 



Grey limestone blocks are also recorded from the Chirchun area, 

 Griesbach and Diener likewise consider them Dachsteinkalk. 

 7. Lower Lias (E. Bs. 4, 6, 7, 16, 17 on map, plates 3 and 8). No 



1 This species of hitherto doubtful geological position I found recently in the 

 topmost " Daonella beds " of the Bambanag cliff, immediately below the " Hautf - 

 ites beds," Diener.
