sub-opposite, and deeply divided, and were probabl}' reduced in com- 

 parison with the (as 3^et unknown) sterile fronds. The great majority 

 of the pinnules appear to have been fertile, and the seeds were 

 borne at the extremities of the segments. The seeds thetnselves are 

 very small, their average length being 1 mm. and their greatest width 

 0.75 mm. They were oval, and have rather Sharp longitudinal ridges. 

 There is reason to suspect that the seeds were enclosed in cupules, 

 though it is not possible to demonstrate the same. „The interest of 

 the specimen lies in the fact that we have here the very rare 

 instance of a female frond, undoubtedl}^ of the Sphenopterid t\'pe, 

 bearing small seeds, probably enclosed in cupules." The namegiven, 

 is Carpolithiis Natlwrstij and the inferences are all in favour of the 

 conclusion of the fossil within the Lyginodendreae. M. C. Stopes.

 cites vogesiacus, Schimper and Mougeot. (The Geol. Mag. Decade 

 5. Vol. VI. 1. p. 11 -U. 1908.) 



This paper is based on a specimen discovered by Mr. Wills, 

 and to be described by him in his forthcoming paper on the Keuper 

 rocks. Mr. Arber discusses the affinities of the plant, which he him- 

 self previously described as a member of the Cycadophyta. Mr. Wills' 

 new specimen proves that the plant had its big, Cordaiteslike leaves 

 attached directly to the main axis, in a spiral manner, and was in 

 this like Cordaites, but at the same time, also not unlike large 

 leaved Monocotyledons. In the absense of fructification it is impossible 

 to determine the true nature of the plant, but Mr. Arber does not 

 favour the view that it has any afifinity with the Monocotyledons, 

 while at the same time temporarily retaining the old name Yticcites 

 vogesiaciis, instead of the new one he had recently instituted, viz. 

 Zamites grandis. M. A. Stopes.

This paper gives an account of the fossil plants found in the 

 cores w^hich were obtained in the course of the borings in the Kent 

 coalfield. The plants are shortl}- described, with a few of the more 

 important references to the literature for each. The plants include: 

 Calamites, pith casts which suggest comparison with C. dstt; Anula- 

 ria sphenophylloides, which has larger leaves than other specimens, 

 and is ver}^ abundant; Sphenophylhini ctineifolmni, leaves and stems 

 of which are common; Neuropteris scheuchseri, which is by far the 

 commonest plant in all the beds in the Waldershare boring; several 

 other species of Neuropteris; Odontopteris (one species); Alethopteris 

 (two species); Trigonocarpus; Pecopteris (two species); Mariopteris\ 

 Sphenopteris; Ereniopteris and Cardiocarpus. There are also two 

 species of Lepidodendron , Stigtnaria, fragments of Cordaites leaves, 

 and small seeds of Cordaicarpiis. A discussion follows on the horizon 

 of the beds. The author concludes that they belong to the 'Upper 

 Transition Series', the 'Staffordian' of Dr. Kidston's new Classi- 

 fication. M. C. Stopes.
