Description. 

 ( Coral reefs often enclosing fallen 

 I masses of White Limestone or 

 I other rocks. 



I White or buff-coloured marls with 

 \ Hint, often foraminiferal. 

 I Gravels and shell beds atBowdenand 

 I Port Morant on the south-enst 

 I coast. 



Hard massive "Cockpit" Limestone. 

 I Foraminiferal chalky bedded limc- 

 ■^ stones and flint bands. Locally 

 I missing. 



/ i\Iassive yellow limestones, yellow 

 marly limestones, shale and lignite 

 j bands. 



Fossils ; Carolia in higher part, 

 > Vctates in lower. 

 ( Flysch-like shales and Brockram-like 

 conglomerates, with derived Cro- 

 1 taceous and fresh or slightly rolled 

 j contemporaneous Eocene fossils. 

 ^ Locally missing. 



. Fossiliferous limestone reefs, with 

 Budists and other fossils inter- 

 calated among shales and conglo- 

 merates. 

 Bed shales, with Tri{ionia,Roiidairia, 

 Bnculitcs, Hamilcs, etc. 



■ Metamorphosed or semi-metamor- 

 phosed equivalents of the HI"o 

 Mountain Series.
