IN SOUTHERN INDIA.

have a markedly estuarine~facies, appear to be most related 

 to the upper cretaceous rocks of South India. Several genera 

 and species not known to Hislop were since obtained by 

 Mr. A. J. Stuart, when Sub- Collector of Rajahmundry, and 

 by Mr. King. 



The great shingle formations near Rajahmundry are 

 regarded by Mr. King as equivalent to the Cuddalore sand- 

 stones of Mr. H. F. Blanford. 



Evidence of the great advance seaward of the Kistna- 

 Godavari alluvial (delta) plain was obtained far inland at a 

 place not far from the south end of the Koler lake, where 

 fossil marine shells and crabs of living species were found 

 by Mr. Peters, C.E., Executive Engineer at Bezwada, when 

 excavating for the foundation of some irrigation buildings. 



On the completion of the Nellore-Kistna coast tract, the 

 writer was sent southward to take up the large unknown 

 tract east and north-east of Madura. As it was considered 

 highly probable that cretaceous rocks might be found in that 

 terra incognita, the author took a rapid run over the typical 

 rocks in Trichinopoly District to renew his acquaintance with 

 them after an interval of 18 years. This visit resulted in 

 his forming a very fine collection of cretaceous fossils, in- 

 cluding many important novelties (see above). The survey of 

 the greater part of the terra incognita showed, unfortunately, 

 little of interest ; the hoped-for cretaceous rocks were not 

 met with and nearly the whole area was found to be occupied 

 by lateritic formations, chiefly of the sandy variety. The 

 eastern part of the country is a difficult one to travel over 

 from its very sandy nature, and a most unsatisfactory one to 

 survey geologically from the badness of the only available 

 topographical map, sheet 80 of the Indian Atlas. A vast 

 number of villages are not given ; of many, the positions of 

 which seem identifiable in the map, the names they now go 

 by will not agree with those given. This state of things
