162 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jail. 27, 



perary, Graptolithus priodon is remarkably abundant in close prox- 

 imity to fossils of an Upper-Llandovery type. 



With the permission of the Society, I shall reserve for another 

 occasion the continuation of this subject, when I hope to have been 

 able to complete my examination of localities in the north of Ireland, 

 some of which are of great interest. 



Discussion. 



Mr. CiRRUTHERS remarked that while almost all observers have 

 referred these creatures to the Hydrozoa, there was an impression 

 abroad, founded on a misconception of a remark of Prof. Huxley's, 

 that he classed them as Polyzoa. He had, however. Prof. Huxley's 

 authority for saying tbat he did not so regard them. 



2. Notice o/ Plant-remains /rom beds interstratijled with the Basalt 

 in the county of Antrim. By W. H. Baily, Esq., F.G.S. 



(Abstract.) 



The deposit referred to by the author was discovered by the late 

 Mr. G. Y. Du Noyer in cuttings of the Northern Railway of Ireland, 

 near Antrim ; the plant-layer consists of a red clay deposit from 4 to 

 8 inches in thickness, separated by a bed of 10 or 12 feet, contain- 

 ing nodular iron-ore, from the underying basalt, and by earthy beds 

 of about equal thickness from the superficial basaltic rock. 



The author regarded a large cone as that of a true Pinus, and 

 branches of another coniferous tree as belonging to a Sequoia nearly 

 allied to 8, Sternhergi, Heer ; of this species he thought a small 

 imbricated cone might possibly be the fruit. Other fragments of 

 Coniferae seem to belong to Cupressites or Taxites. The fossils consist 

 chiefly of leaves of true Dicotyledonous plants. The author com- 

 pared some of them with species of RhamniteSy Olea, Fagus, and 

 Quercus. Leaves of endogenous plants, such as Sedges and Grasses, 

 occur not unfrequently. A large mass of fossil wood of dicoty- 

 ledonous structure was obtained from the bsematitic deposit. Seed- 

 like bodies are also found. The plant-remains are accompanied by 

 by a few elytra of Beetles. 



The author remarked that these plant-remains differ as a group 

 from those of the island of Mull. Their alliance appears to be with 

 Mid-European forms ; and they are certainly of Upper-Tertiary age, 

 probably Miocene. 



Discussion. 



Mr. Carruthers observed on the difficulty of determining species, 

 or even genera, satisfactorily, from such fragmentary evidence as 

 that adduced by Mr. Baily. He considered that the small cone 

 did not belong to Sequoia^ inasmuch as the cone of Sequoia was not 

 composed of imbricated, but of adnate, peltate scales. The wood 

 was not only dicotyledonous, but coniferous.
