Pakeozoic Species mentioned in "Fossil Flora!' 351 



Brongt,, and Lepidodendron Sternherf/ii, Brongt., to each other 

 — whether specifically distinct or synonymous — but at pre- 

 sent I must admit my inability to grasp the characters which 

 are said to distinguish Le2ndodendro7i Sternhergii, Brongt., 

 from Lepidodendron ophiurus, Brongt. 



PI. V. Ulodendron majus, L. and H. 

 Locality. — Jarrow Colliery, near Newcastle-upon-Tyne. 

 Horizon. — Lower Coal-Measures. Eoof of Bensham Coal. 



PL vi. Ulodendron minus, L. and H. 



Locality. — South Shields Colliery, county of Durham. 



Horizon. — Lower Coal-Measures. Eoof of High Main 

 Coal. 



Remarks. — I have already on several occasions expressed 

 the belief that Ulodendron majus and Ulodendron minus 

 are only different conditions and ages of the same species, 

 and to prevent further confusion have recently adopted 

 Konig's specific name for these plants, and now class them 



as SiGILLARIA DISCOPHORA, Konig sp.^ 



The counterpart of the type of U. minus is still preserved 

 in the "Hutton Collection." 



PI. vii., fig. 1. Lepidodendron acerosum, L. and H. 



PI. viii., figs. 1, 2. Lepidodendron (?) acerosum, L. and H. 



Locality (pi. vii., fig. 1). — Bensham Colliery. 



Horizon. — Lower Coal-Measures. Roof of the Bensham 

 Seam. 



Locality (pi. viii.). — Felling Colliery, near Kewcastle-upon- 

 Tyne. 



Horizon. — Lower Coal-Measures. Ptoof of Low Main Coal. 



Remarks. — The types of these figures appear to be lost, 

 but from the examination of other specimens in the collec- 

 tion, there cannot remain any doubt that the Lepidodendron 

 acerosum, L. and H., is a Lepidophloios, and similar to the 

 plant named Lepidophloios carinatus by Weiss.^
