no dias^nostic characters for the new genus and the many new species he proposes in 

 this important memoir. 



Carruthers, W. On some supposed Vegetable Fossils. Quart. Journ. Geol. Soc, 

 vol. sxvii. pp. 443-448, pi. xix. 

 The author describes some physical impressions and zoological structures, which 

 have been erroneously supposed to belong to the vegetable kingdom. 



^ — - — On two tFndescribed Coniferous Fruits from the Secondary Eocks of 



Britain. Geol. Mag., Vol. VIII. pp. 540-544, PI. XV. 

 The author describes the cone of a second species of Pine associated with a second 

 species of Sequoia from the Gault, and shows that the type of Pine associated with 

 the Wellingtonias of the Gault was the same as that now found with these trees in 

 "Western North America. 



■■ On the History and Affinities of the British ConifercB. Abstract. Brit. 



Ass. Eeports, 40th Meeting, p. 71. 

 The author traces the appearance, development, and affinities of the fossil and 

 recent Conifers of Britain. 



On the Sporangia of Ferns from the Coal Measures. Abstract. Brit. 



Ass. Eeports, 40th Meeting, p. 71. 

 The sporangia are referred to Hymenophyllaceous Ferns. 



Eemarks on the Fossils from the Eailway Section at Huyton. Abstract. 



Brit. Ass. Eeports, 40th Meeting, p. 71. 

 The author described in general terms a series of Carboniferous fossils collected at 

 Huyton by the Eev. H. Higgins. 



'^ Note on an Antholithes discovered by C. "W". Peach, Esq. Abstract. Brit. 



Ass. Eeports, 40th Meeting, p. 72. 

 The specimens showed that Antholithes were the spikes of Cardiocarpon. 

 Dawson, J. W. On Spore-cases in Coals. (Eeprinted from ' Silliman's Journal,' 

 April, 1871.) Ann. Mag. Nat. Hist. 1871, pp. 321-329. 

 The author figures some spore-cases from a brown bituminous shale of Upper 

 Devonian age from Kettle Point, Lake Huron, which he names Sporangites Suronensis 

 and he considers they belong to the species of Lepidodendron found in the bed. His 

 Sporangites glabra is " almost without doubt the spore-cases of L. corrugatum." He 

 has foimd spore -cases in many American coals, but he considers their presence as 

 " accidental rather than essential to coal-formation." 



-^ The Fossil Plants of the Devonian and Upper Silurian Formations of 



Canada. Montreal and London, 1871, p. 100, pi. i.-xx. 

 The author gives the results of his researches in these strata prosecuted for several 

 years, and here brought to a conclusion, so far as the accessible material will admit. 

 He reports more than 120 species of land plants. The work is, with a few additions 

 and some necessary changes, the same as the memoir read to the Eoyal Society in 

 1 870, and now in its archives. Twenty-six new species are named, mostly founded 

 on very imperfect materials, and imperfectly described. These new species are in- 

 cluded in the systematic list. 



On New Tree-ferns and other Fossils from the Devonian. Quart. Journ. 



Geol. Soc. vol. xxvii. pp. 269-275, pi. xii. Abstract. Geol. Mag., Vol. VIII. 

 p. 231. 

 Three Fern stems and some other fossils are described in this paper from the 

 Devonian rocks of North America. 



On the Structure and Affinities of Sigillaria, Calaniites, and Calamoden- 



dron. Quart. Journ. Geol. Soc. vol. xxvii. pp. 147-161, pi. vii.-x. 

 The author holds that Calamiies and Lepidodendron are distinctly cryptogamous, 

 and are related to, or included in Hquisetacecs and Lycopodiacece ; but Calamodeiidron 

 seems to form a connecting link between Calamites and the ribbed Sigillaria., while 

 Lepidophloios seems to connect Lepidodendra with Sigillarice of the Favularia type. 

 On the other hand, the ribbed Sigillarice may be related through Dadoxylon to the 

 modern Conifers, and the Favularia may be related to the Cycads. 

 Heer, Oswald. On the Carboniferous Flora of Bear Island. Abstract. Quart. 

 Journ. Geol. Soc. vol. xxvii. p. 1 ; Ann. Mag. Nat. Hist. vol. vii. p. 175. 

 The author compares the flora of this island with the plants found in the Yellow 

 Sandstones of Ireland, and concludes that they are of Lower Carboniferous age, and 

 form a special group, for which he proposes the name " Ursa-stage."
