PI. I. Fig. 2. Section of tlie same slab, showing tlie outliae of tlie rippling 

 and the cross section of the double depression of the Annelide 

 tracks — full size. 

 .3 and 4. Sketches of Annelide markings on the surface of fine 

 earthy sandstone from Eorhadi near Nagpur, of full size, 

 given for comparison. 



PL IT. Map of the Taleheer Coal Pield — Scale, four miles equal one inch. The 

 Topographical portion of the Map has been copied, with very 

 slight alteration, from the Maps prepared under the superin- 

 tendence of Captain Saxton, Deputy Surveyor General, for 

 the use of which the Geological Survey is indebted to the 

 kindness of Major Thuillier, Surveyor General's Office, 

 Calcutta. 



PI. III. Sections of the Taleheer Coal Pield. 



Section 1 extends from Sarasua Hill, in the North-West of the field, 

 in a right line to Gopalprasad, and thence Southward and East- 

 ward to Earakprasad. This section shows the relations of the 

 several groups of rocks occurring in the district, and the mode 

 in which they have been faulted. 

 Section 2 extends from the Tikiria Nullah, on the Northern boundary 

 of the field, to Gopalprasad, where it shows the relations of 

 the carbonaceous shales to the accompanying rocks ; and thence 

 the section extends to the Southern boundary of tJie field at 

 JorasLnga. 

 These sections are laid down to the same scale for heights and 

 distances, namely, two miles to the inch, or double the linear 

 scale of the accompanying Map. The outlLne of the surface is 

 only approximately correct : the dense jungle and inaccessible 

 nature of portions of the district, and the want of any accui'ate 

 levels, preventing greater accuracy.
