secure. In the first volume of the British Museum Catalogue of 

 Wealden plants, a small brauch similar to the plant now described 

 was described under the title "Planta incertae sedis", but a compa- 

 rison with Lycopodiiim was suggested. In the case of the specimens 

 now described and named, treatment with nitric acid and potassium 

 chlorate dissolved the sporangial walls, but revealed the structure 

 of numerous microspores and a few macrospores. The microspores 

 adhered in tetrads and were 04 mn. in diameter, and had a tuber- 

 culate outer coat. The megaspores were 0.3 — 0.35 mn. in diameter 

 and were oval or nearly spherical. The species is called Selaginel- 

 lites Dawsoni after a collecter who has obtained many Wealden 

 plants now in the British Museum. M. C. Stopes.

Most of the specimens here described are from the Hugh 

 Miliar Collection in Edinburgh. The material consists of petrified 

 Sterns and other fragments which are not always very well preser- 

 ved, but as very few Mesozoic plants are structurally known, are 

 described in detail. Five new species are described. 



Thiniifeldia scoticn sp. nov,, from a specimen discovered by 

 Prof. Nathorst, has blunt rounded lobes. 



Brachyphyllum cathense sp. nov., was described as an "Imbri- 

 cated Stern"' by Hugh Miller in 1857, and is imperfectly petrified. 

 Sections of the short, fleshy leaves are described as agreeing in 

 many respects with the Cretaceous Brachyphyllum s. 



An imperfectly petrified leaf of Taxites Jejfreyi Sew. is descri- 

 bed, and suggests comparison with a species of Podocarpus. 



Masculostrobus Woodwardi sp. nov. was figured by Miller in 

 1857, and the anatomical features now described, so far asthej'go, 

 favour the view that the specimen represents an immature micro- 

 strobilus. 



Conites Juddi sp. nov. is defined as follows: Cones, which vary in 

 size from 3 cm. X 2.5 cm. to 9 cm. X 4 cm., almost spherical or 

 elongate oval in form. A thick axis bears spirally disposed. thick 

 scales, attached by a comparatively slender base. Forms « and S 

 are described, and the affinities of the cones are with the Arauca- 

 rians. "Characters now met with in Araucaria and Agathis respec- 

 tively are combined in the sporophylls of Conites Juddi'". 



Strobilites Milleri sp. nov. is described from a Single impression. 

 "Though too imperfectly preserved to be diagnosed with any degree 

 of certainty, it may perhaps be best described as a lax spike of 

 sessile seeds". Similarity to Podocarpus spicata is suggested. 



Cedroxylon Hornei sp. nov. is founded on a petrified stem 5 cm. 

 in diameter. A figure is also given of Ginkgo digitata iorma. Huttoni. 



The fossils described extend the list of known Jurassic plants 

 of Scotland. M. C. Stopes.
