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

 Geol. Soc. , vol. xxviii. pp. 161-169. 

 The author considers that the fossil plants from Bear Island are more nearly- 

 related to the Carboniferous than to the Devonian, and he consequently places them 

 and the fossils of Yellow Sandstones of Ireland, which he believes to be of the 

 same age, as the fundamental series of the Lower Carboniferous system, under the 

 name of the Ursa stage. 



On Cydostigma, Lepidodendron, and Knorria, from Kiltorkan. Quart. 



Journ. Geol. Soc, vol. xxviii. pp. 169-172, pi. iv. Abstract. Geol. Mag., 

 Vol. IX. p. 134. 

 Prof. Heer maintains the specific distinctness of Cydostigma Kiltorkense, 

 Haught., C. minutiim, Haught., Knorria acictdaris, Gopp., and Lepidodendron 

 Veltheimiamim, Sternb., all from Kiltorkan, which I had maintained to be 

 fragments of the same species. He figures and describes his species.

 Ravenshead collection of Fossils, Free Public Museum, Liverpool. Pro- 

 ceedings Liverpool Geol. Soc. 1872, pp. 71-75, with plate. 

 The curious stems figured and described by the author are amorphous casts of 

 fern-stems of the Caidopteris type. 



Macloskie, Rev. Dr. On the Silicified Wood of Lough Neagh, vnth Notes on 

 the Structure of Coniferous Wood. Abstract. Journ. Bot., vol. x. pp. 93-95. 

 The author describes Cupressoxylon Pritchardi, Kr., and gives an account of the 

 conditions under which it occurs. 



Marrat, F. p. On the Fossil Ferns in the Ravenshead Collection. Proceedings 

 Liverpool Geol. Soc. 1872, pp. 4-16. Plates 1-13. 

 The author enumerates 62 species, 9 of which he considers undescribed, and he 

 gives them names. The figures and descriptions are scarcely sufficient for inde- 

 pendent investigators to determine the characters which distinguish them from 

 already described species.

 Dreside, Tillicoultry, etc. Abstract. Trans. Edin. Bot. Soc. vol. xi. p. 342. 

 An enumeration of some of the more remarkable fossils the author collected in 

 the localities specified. 



On a Cone of Flemi7igites gradlis attached to its stem. Abstract.

 The author describes the specimens he had found. 

 Williamson, W. C. On the Structure of the Dictyoxylons of the Coal-measures. 

 Abstract. Report Brit. Assoc. 1871, pp. ill, 112. 

 Three species are shortly described — Dictyoxylon Oldhamiuvi, D. radicans, and 

 D. Grievii. 



On the Organization of the Fossil Plants of the Coal-measures. Part i. 



Calamites. Phil. Trans, vol. clxi. pp. 477-510. pi. xxiii.-xxix. 

 The author figures and describes in detail the specimens in his cabinet, and 

 proposes to divide the Calamites into two generic groups, retaining Calamites for 

 the stems which have no infranodal canals, as indicated by the absence of verticils 

 of round or oblong scars, and adopting Calamopitus for those which have such 

 canals. 



On the Organization of the Fossil Plants of the Coal-measures. Part 



ii. Lvcopodiace^ : Lepidodendra and Sigillarice. Pliil. Trans, vol. clxii. 

 pp. 197-240, pi. xxiv.-xxxi. 

 The author figures and describes in detail sections oi Lepidodendron, Ulodendron, 

 Halonia, Diploxylon, and Sigillaria. He considers Atiabathra of Witham to be 

 the same as Diploxylon, and among the stems described he distinguishes four 

 species to which he gives specific names. He considei's the whole belong to the 

 same group, and that they are Lycopodiaceous. 



Notice of further Researches on the Fossil Plants of the Coal-measures, 



in a Letter to Dr. Sharpey, Sec. R.S. Proc. Roy. Soc. vol. xx. pp. 95, 96. 

 The author records the progress of his investigations into tiie nature of a 

 Lepidodendroid plant and its fruit from Burntisland, and of an AsteropJiyllitcs from 

 Lancashire, which he proposes to submit to the Society speedily.
