[ February. 
Annual Report op the G-eological Survey op India, and op the Geological 
Museum, Calcutta, for the year 1879, 
In the Peninsular area there were five survey parties at work during the field 
season of 1878-79. 
As announced in the annual rejiort for 1878, Mr. Foote took up new ground 
S. India : *0 south of Trichinopoly, to trace out in that direction 
Mr. Foote. any remnants of the deposits of various ages already 
knoivn along the coastal region to the north. He carried his woik through the 
Pudukotai State to the latitude of Madura, hut nothing of interest was found. 
The irregular houndary of the gneiss occurs at a distance of about 35 mdes from 
the coast, and the intervening ground is principally occupied hy the latentic 
formation, overlying and closely connected with the Cuddalore-sandstone gioup, 
first described by Mr. H. P. Blanford in the Trichinopoly area. Its exact age is 
still undetermined—probably older tertiary. The laterite overlaps it to the west, 
and rests on the gneiss. Mr. Foote’s account of this ground is published in the 
August number of the Records. 
Mr. Foote’s map and description of the North Arcot district, published in the 
Records for November, were compiled from observations made many yeais ago 
by himself and other members of the Survey. 
In the Pranhita-Godavari area, besides the general extension of his survey of 
Godavari • ^1*® Gondwana rocks of that basin, Mr. King has fairly 
Mr. King. succeeded in maintaining a distinction of upper and lower 
in the Kota-Maleri series, so far as established by overlap, which is still the pirn- 
cipal feature of unconformity between the several groups of the Gondwana 
system. Within the local basin we are indeed still unable, as was shown by 
NIr. Hughes (Records, XI, page 29), to demarcate the groups closely, but Mr. 
King has found that to the south there are no representatives of the Maleri clays 
between the Kota beds and the Sironcha sandstone, which he now recognises as 
belonging to the Kamthis (lower Gondwanas). The conjectured intercalation of 
the peculiar fossils of the two zones has not been confirmed, so as to modify this 
stratigraphical indication; and thus the original distinction indicated by the 
liassic fossils of the Kota beds and the rhaito-triassic fossils of the Alaleri clays 
stands for the present confirmed. (See Pal. lud., Ser. lA , 2 ; Manual, p. 151.)
