(Similar concrete occurs in a stream near Doonira, where they 

 J contain the Osirea lingua more abundantly). 



I 17. — A large thickness of brown and gray strong sandstones, with 

 I calcareous layers near the base. 



Ll 6. — Thin conglomeritic and ferruginous band.

Unconformity. 



f 15.— Sandy and muddy shales and clays, including a few harder sand- 

 stone bands and ripple-marked layers. The thickness of these 

 is about 200 feet. 

 In the upper part a rusty sandy bed has numerous casts of a 



small Cerithium with some of larger size. 

 Lower down a rubbly band with small Pecten, Ostrea sp., and 

 Bryozoa incrusting some of the shells ; also bored claystone 

 nodules. 

 Below these Balani in clusters abound in a shelly fragmentary 

 layer. 

 14.— Highly fossiliferous shelly rags and. marly limestones (2 or 3 feet 

 thick) among rubbly and softer marly beds. 

 These beds include the scallop and oyster band, the Conus and 

 FoWe beds, and also contain Naticar s^.,Cyprea, Scalaria, Pecten, 

 Solen, Echinoderms, casts of large Strombus, Serpula tubes, &c. 

 In one of the lower marly beds Placuna abound, together with 

 OstrecB and Ecldnoderms. 

 J 13. — Mottled, pink, purple, and white sandy shales and muddy beds. 



Break. 

 12.— Nodular, lumpy, pseudo-conglomerate band, among muddy and 

 sandy shales, and dark -yellow, marly, hard beds with Nummu- 

 lites spira. 

 11. — Yellow and rusty raggy beds with Turritella and Nucula ? &c. 

 10.— Soft and friable, fine, streaky, sandy shales. 

 9. — More compact and somewhat flaggy calcareous sandstone and 

 marl, parts largely composed of shelly fragments of Placuna; 

 also containing Nucula, Turritellce, Nummulites exponens, N- 

 perforata, and N. spira. 

 Break (40 feet of sub-recent accumulations seen in the river cliff) 

 8. — Mottled, white, and red sands and soft gypseous clays, with two 

 pseudo-conglomeritie bands of whitish clay nodules and ferru- 

 ginous pebbles. The lower of these associated with a layer of 

 black gypsum — a Turritella band. 

 7. — Mottled, richly coloured red, fine, areuaceous clay, ferruginous 

 oyster bed at base.
