90 HUGHES : WARDHA VALLEY COAL-FIELD. 



occurred, to the limestone that was associated with them, and we jointly 

 surveyed the critical portion of the section. The conclusion we arrived 

 at was, that there are two beds of limestone, an upper and a lower, and 

 between them occurs a succession of white argillaceous shales in which 

 fish, a number of small shells, and Cyprida were found. It is not possi- 

 ble to distinguish lithologically between these shales and some occurring 

 amongst the inter-trappeans, but their position between limestones 

 possessing the mineral features of the typical Lameta limestone of 

 Jabalpur shews that they must be classed with that series. 



The fish, which are about the size of sardines, were taken to England 

 for identification, but the slabs in which they occurred were unfor- 

 tunately not carefully enough padded, the fish were injured, and their 

 affinities could not be determined. 



The fish beds of Dhamni are represented near Dongargaon; and 



Hislop alludes to the discovery of a specimen*

" which consists of a head, with a long muzzle 



armed with formidable sauroid teeth, and rows of smaller ones/'' and which 



" Sir P. Egerton considers to be allied to the Sp/iyrcsnodus of the London 



clay." We were not successful in procuring any specimens from this 



locality. The strata are somewhat more calcareous here than at 



Dhamni. 



No Lametas have been met with in the Nizam's Dominions; but in 

 the Wun District they occupy the ground between Wanjra and 

 Wargaon, and the strip from Nimbora to Chichara. None of the 

 typical limestone occurs, but the extra varieties alluded to in the 

 descriptive summary are developed south of Wargaon. 



The beds near Nimbora are red and green clays and thin -bedded 

 sandstones. A short but instructive section of the clays is seen at the 

 outlet corner of the tank. They look like Talchir mud beds, but their 

 position proves that they are in no way connected with that series.
