A description of a large trunk of a Coniferous tree of 

 Tertiary age from the Macquarie Plains, Tasmania, first 

 described by Sir Joseph Hooker in 1842 and now exhibited 

 at the British Museum. The structure of the wood is beautifuliy 

 preserved. A füll description of the anatomy is given, with 

 figures of the trunk itself, ant of sections of the wood in different 

 directions. Arber (Cambridge).

 Plate I, and text figure. 1903.) 



This paper contains a series of notes on the fossil plants 

 of the highest beds in the South Lancashire coalfield, 

 which belong to the horizon known as the Upper Transition 

 Series, and are immediately antecedent to the Upper Goal 

 Measures. The genus Poacites of Lindley and Hutton is 

 shown to consist of imperfectly preserved Caramitean casts. 

 A Calamitean ieaf-sheath in which the free segments are reduced 

 to teeth-like appendages is described. Figures are given of 

 Lepidodendron dichotomum, Zeiller, a rare species in Britain. 

 Specimens of Neuropteris Scheuchzerl, Pecopteris Miltoni, and 



Lepidodendron lycopodioides are also figured.

KlDSTON, R., Onthefructification of Neuropteris Heier c- 

 phylla, Brongniart. (Phil. Trans. Roy. Soc, Ser. B., Vol. 

 197, p. 1—5, Plate I. and text figure I. 1904.) 

 This important paper describes certain specimens, preserved 

 in small ironstone nodules, from the Goal Measures at C 1 o s e 1 e y, 

 near Dudley, South Staffordshire, which show seeds 

 referable to the genus Rhabdocarpus Göppert et Berger, each 

 attached to a fragment of a pedicel bearing the foliage of 

 Neuropteris heterophylla Brongt. This is the first instance in 

 which the foliage of a member of the Cycadofilices has been 

 found actually in continuity with a seed, and it confirms the 

 conclusion, earlier arrived at by Professor Oliver and Dr. 

 Scott on other evidence, that the seed-bearing habit existed 

 among the members of this group. The specimens described 

 here are not petrified. The seeds are of the radiospermic type, 

 and about 3 cm long. Their general form is oblong, but they 

 are gradually contracted from about the middle into a somewhat 

 sharp point. The outer surface shows numerous iongitudinal 

 ribs, formed by bands of sclerenchymatous tissue in the outer 

 envelope of the seed. They differ little from Rhabdocarpus 

 tunicatus of Renault, or from R. subtunicatus Grand' Eury, 

 except in being narrower in proportion to the length.
