Argillaceous sandstone (at Sironcha or Chiranja, six miles down the river) [= the 

 Silewa<fa plant-sandstone, near Nagpur = Damuda group of Bengal]. 



Mr. Hislop lias also obtained Estherice similar to those of Kota from Katanapali, 

 about fifteen miles north of Kota. " Here the argillaceous limestone is about eight feet 

 deep, thick -bedded above, more fissile below ; and still lower down passing into white 

 laminated strata, as at Kota. The slaty limestone abounds with scales of Lepidoius, and 

 the underlying wdiite shale with Estheria." ('Bombay Asiatic Soc. Journ./ 1862, vol. vi, 

 p. 201.) 



I may here mention that in the seventh volume of D'Archiac's ' Histoire des 

 Progres de Geologic' (p. 624, &c.), the reader wiU find a resume of all that w^as known 

 about the "Jurassic Freshwater Basin of Central India" down to the date of that 

 volume. 



Habitat. — None of the organic remains yielded by the Kota beds above referred to 

 have marine characters, if we except the Lepidoid Eishes as doubtful evidence. The 

 Cypridm associated here with the Estheria are such as live in fresh water at the present 

 day. (See Appendix.)
