162 PEOCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jail. 7, 



M. de Verneuil informs us* that Dr. Gceppert is of opinion that, in 

 general, the Permian flora offers in its composition a great resem- 

 blance to that of the Coal-formation, fourteen or sixteen species being 

 common to the two. I shall not pretend to offer a complete list of 

 those hitherto recognized, but shall merely quote the following : — 



1. Calamites approximates, Schloth. Tynemouth ; Manchester. 



2. Cistii, Schloth. Tynemouth. 



3. nodosus ?, Schloth. Tynemouth. 



4. Suckovii, Brong. Tynemouth ; Manchester. 



5. Sigillaria reniformis, Brong. Tynemouth. 



6. Odontopteris Schlotheimi, Brong. Tynemouth. 



7. Neuropteris Soretii ?, Brong. Tynemouth. 



8. — angustifolia, Brong. Tynemouth. 



9. Cyatheites arborescens, Schloth. 



10. villosus, Brong. Manchester. 



11. Oreopteridis, Goipp. Manchester. 



12. Alethopteris Mertensioides, Gutb. 



13. Lonchitidis, Sternb. Manchester. 



14. Sphenopteris latifolia, Brong. Tynemouth. 



15. irregularis, Sternb. Manchester. 



16. coralloides, Gutb. Manchester. 



17. Walchia piniformis, Schloth. 



18. Guglielmites umbonatus, Sternb. 



19. Trigonocarpum postcarbonicum, Giimbel. 



20. Nceggerathi, Lindl. 8r Hutt. Tynemouth. 



21. oblongum, Lindl. 8f Hutt. Tynemouth. 



22. Cyclocarpon marginatum, Artis, sp. 



23. tuberosum, Gein. t 



24. Noeggerathia palmseformis, Gcepp. Tynemouth. 



25. Araucarites Schrollianus, Goepp. 



26. — — Brandlingi, Lindl. 8f Hutt. Tynemouth. 



27. Sagenaria dichotoma, Sternb. Manchester. 



28. Dictyopteris neuropteroides, Gutb. Manchester. 



The thirteen species to which the locality " Tynemouth" is attached 

 were identified by Mr. R. Howse as common to the Lower New Red, 

 or Rothliegende, and the Coal-measures of the north of England, 

 the former of which he thinks should more properly be considered as 

 the upper portion of the true coal-measures. Seven, namely Nos. 13, 

 14, 16, 17, 18, 21, and 23, are mentioned by Dr. Geinitz as common 

 to the German Rothliegende and Steinkohlen-formation. Mr. Binney 

 has also recorded the occurrence of common coal-plants of the genera 

 Sigillaria, Lepidodendron, and Calamites in the Lower Permian 

 strata of the north-west of England. Those to which I have ap- 

 pended the word " Manchester " are taken from.p. 313 of Dr. Gei- 

 nitz's valuable work ' Dyas.' 



Among the Entomostraca, Messrs. Rupert Jones and J. Kirkby have 

 identified the following species as being common to both periods in 

 Britain : — 



1. Cythere elongata, Munster, 1830. 4. Cythere (Bairdia) plebeia, Beuss. 



2. inornata, M'Coy, 1844. 5. (Bairdia) Schaurothiana, 



3. (Bairdia) gracilis, M'Coy, 1844. Kirlcby. 



Among the Annelida, Mr. R. Howse informs me that Microcoria 



* Bull. Soc. Geol. Fr. 2 rae ser. vol. xix. p. 600. 



t Mr. Howse considers these so-called fruits to be*fish=scales (Holoptychius ? 

 sp.).
