till lately tliat these South Indian cretaceous rocks were limited to the Trichinopoly 
basin, but more recently traces of them have been found further north. Foote 
already met with loose blocks of a cretaceous rock in the neighbourhood of Sri. 
permatur,! but was unable to trace the bed in situ. King"\ on the contrary, 
discovered richly fossiliferous rocks, of probably cretaceous age, in the Godavari 
district, below the trap which there occurs sporadically. These he regards as 
Lametas, but the fossil species there collected require to be more accurately 
determined. 
The most northerly localities with marine cretaceous rocks on the east 
side of the Indian Peninsula are the Khasi and Garrow hills, or, as Medlicott 
terms it, the Shillong plateau. On descending from.Cherra Punji to the south, 
one meets below the nummulitic beds first of all a sandstone 200 feet thick 
and of uncertain age, fossils being entirely unknown in it. Below it alternate 
limestones and sandstones, with a thickness of about 500 feet, which appear 
finally to terminate with conglomerates at their base.® Stoliczka* * has submit¬ 
ted the fossils collected by Medlicott to a careful examination, and found that 
the highest fossiliferous beds contain Corals and Bryozoa; in the middle beds 
Cephalopoda pi-edominated ( e. g., Amm. plmmlatus, dispar, Orliignijanus, Gein., 
pacificus, Stol. &c.), while the lower part which is best exposed on the Theria Ghat 
includes numerous gusteropods and pelecypods, the greater number of which 
agree with South Indian species, but amongst which there are also many 
novelties. The cretaceous beds now under consideration appear, on the whole, to 
correspond most nearly with the South Indian Arrialoor group. 
To the southward of these beds cretaceous rocks appear again below the 
nummulitic deposits in Burma,® but they require closer examination. 
This is the last spot at which marine mesozoic formations ajipear in India. 
The remaining beds of similar age are vast accumulations of sandstone which 
show themselves by their inclusions of plant-remains and by the total absence 
of marine fossils to have been formed in inland basins. It is impossible for me 
to describe closely and fully the several beds composing these deposits, par- 
ticul'drly as a good deal of uncertainty still exists among Indian geologists as to 
the correlation of the sub-divisions in the different areas of deposition. This 
uncertainty is, however, not unnatural when one considers that the various inland 
basins in -which these beds were deposited were very probably but slightly or not 
at all connected, so that only the palaeontological data can indicate the correspond¬ 
ence of the several groups. The very scattered distribution which these 
deposits exhibit when represented on the map may probably be due just as
