lehacliensis — were obtained from the Permian* and not from tlie 

 Coal-measures. 



The nine other insects discovered in strata of this Age all belong 

 to the extinct genus Blattina, of the Family BlattidcB of the Orthoptera, 

 and the majority of them were obtained from Weissig. Of these 

 Blattldce, five species — JBlnttina ioeissigensis,-\ B. j)orrecta,% B. 

 BucJcerfi,^ B. lehacliensis, and B. gracilis — are new to the list of 

 Paleozoic Insecta; but specimens of the remaining four, viz., B. didyvia, 

 B. antliracopliila, B. carhonaria, and B. Mahri, have also been obtained 

 from the European Coal-measures, and were included in the 30|| 

 species referred to in the paper last mentioned. The specimen of 

 Blattina didi/ma% from the Permian is, for an insect of such vast 

 antiquity, in an unsually perfect state of preservation, the body, 

 wings, and legs being almost entire ; but the other Blattidce are 

 represented only by single wings, or parts of wings, and are of no 

 special interest. 



The Protozoa of this Period are principally represented by 

 Foraminifera, and the Coelentcrata by a few sponges and corals. The 

 Arthropoda include Crustacea, Insecta,** and 3Ii/riopodaff : but no 

 traces of Arachnida have, I believe, been met with, and the Crustacea 

 are much rarer than in any former Age, several Families having en- 

 tirely disappeared. The llollusca are tolerably abundant, especially 

 Braehiopoda and LameUihrancJiiata. 



By far the most interesting fossils of this age belong to the Yer- 

 tehrata, and include fishes — which are comparatively very abundant, 

 Amphibians — various forms of Laljyrintliodontia, and Lacertian, or 

 lizard-like Reptiles. 



The Permian flora was closely allied to that of the Upper Car- 

 boniferous rocks — though most of the species were distinct — and 

 included ferns, tree ferns, JLquiseta, Calamites, and numerous Cycads 

 and Conifers ; there were also several forms which had not been 

 previously met with. 



As already observed, the character of this Period was one of 

 transition : " the oldJJ or Palaeozoic World was passing by, while within 

 " it new types had come forth prophetic of the earth's brighter future."

* Assumiug Dr. Guldenberg to be right, we have thirteen fossil Insects from the Permian uf 

 Europe, viz., two Pakfodictyoptera, two llemiptera, and nine Orthoptera fBlattidicJ.
