ESTHERIA STRIATA. 27 



Feet. Inches. 



4. Coal, not exceeding 7 



5. Fire-clay, with Stigmarian rootlets 5 



6. Reddish sandstone ; many of the beds thin and slaty 30 



7. Shales, with a little poor ironstone 4 



8. Coal (irregular) 10 



9. Yellow sandstone 4 o 



10. Drab, slaty sandstone, passing into argillaceo-arenaceous shale 10 



11. Arenaceous shale, slightly calcareous „ 3 o 



*' These beds dip east by south ; all of them belong to the Mountain-limestone group, 

 though they are not far from its base. 



" No. 1 . This sandstone is overlain by many beds of limestone, and associated with sand- 

 stones, shales, and coals, which form the mass of the Mountain-limestone group, extending 

 into Northumberland. 



" No. 2. The Estherian shale. This contains another Entomostracan form.^ There 

 are also a number of broken fragments of plants ; the most numerous being reed-like 

 stems, longitudinally ribbed, but without joints, Coniferites verticillatus (Tate^), and 

 Sphenopteris Johnstoniana (Tate^). Attached to the plant-stems are species of Sjpirorlis. 

 Scales of Ganoid Eishes are abundant ; and I have determined teeth and scales oiHolopty- 

 cJnus Hibberti in this shale. In the lower part of the deposit I found Chonetes sordida 

 and Nucula gihbosa. This bed, taken in connection with that below it, shows changes of 

 conditions from marine to estuarine, and probably to fresh water. 



" No. 3. This limestone is very fossiliferous, containing — 



Strophomena analoga, 

 Productus giganteus. 

 Productus semireticulatus. 

 Lithodendron junceum. 

 Lithodendron affine. 

 Lithostrotion Portlochi. 



Stenopora tumida. 

 Favosites parasitica. 

 AstrcEopora cyclostoma. 

 Syringopora geniculata. 

 Aulopora gigas.'^ 



"No. 10. In the arenaceous shales I have found Lingula sqiiamiformis, and an elon- 

 gated form allied to, but which may be different from, Lingula mytiloides. 



" No. 11. Here occurs Disciiia nitida. In several of the beds of Nos. 10 and 11 are 

 many Annelid-borings. 



" In arenaceous shales a few yards below the above section, I have found Sangu'molites 

 arcuata^ S. carbonaria, Aviculo-pecten Pera, and Spirifer laminosus." [G. Tate, Eebruary 

 9th, 1861.]
