THE TERTIARY FORMATIONS : occupy the greater portion of the State; 

 dip ; present three facies, namely : lignitiferous clays with remains of 

 vegetables, silicious sandstones and claystones with marine fossils ; and 

 limestones and calcareous marls with marine fossils ; estuary deposits 

 of marine fossils sometimes found in the lignitic beds ; lignitic beds 

 usually separate the marine deposits, 107 ; general section of the Ter- 

 tiary strata, 108 ; doubt as to position of " Lignitic of N. Mississippi ": 

 study of its fossil plants by L. Lesquereux ; comparison of Venericar- 

 dia planicosta from various geological horizons, by Prof. W. D. Moore, 

 109.

II. The Claiborne Group. A. The Silicious Claiborne specially treated ;

 123, 124 ; Section on the Chickasawhay, at Enterprize ; fossils in thig 

 bluff; beds intervening between Silicious and Calcareous Claiborne, 

 125 ; B. The Calcareous Claiborne Strata ; characterised by the pre- 

 dominance of lime ; fossils poorly preserved, except oysters, 126 ; 

 Section on Falling Creek ; beds between the Claiborne and Jackson 

 Groups ; Zeuglodon bones ; fossil leaves and fruit, 127, 128. 



III. The Jackson Group ; "black," and " bald " prairies common ; Zeu- 

 glodon, Eschara, remains of fish, Gryphgea (allied to convexa) common 

 fossils ; upper division matrix of Zeuglodon — lower, shells, figured 

 and described by Conrad, in Waile's Report ; higliesl strata at Canton, 

 128 ; localities, 129 ; Section in railroad cut near Calhoun Station; large 

 skeleton of Zeuglodon found here, 130; Section at Moody's Branch 

 and McNutt Hills, 131 ; fossils found at these places, and comparison 

 of them with Vicksburg fossils, by W. D. Moore, 132, 133 ; other 

 localities continued ; Zeuglodon and other fossils, 134 ; Section near 

 Red Bluff Station, Wayne Co., 135 ; beds between Jackson and Vicks- 

 burg Group, 135 — in this Section, determination of their fossils, list of 

 them, comparison of this fauna with those of Vicksburg and Jackson 

 Strata by Prof. W. D. Moore ; lignitic beds at Vicksburg ; depth 

 according to Prof. W. D. Moore, 136 ; Section in Mr. John Parker's 

 Well, Rankin Co., 137 ; Selenite, 138.
