examples in different states of preservation of the same species, for 

 which we propose the name Lepidoclendron vereenigingense. 

 Feistmantel ^ has figured a very imperfect cast from the Lower 

 Carboniferous of jSTew South Wales, which he compares with 

 L. Volkmannianum, but the specimen is too indistinct to determine. 

 The preservation of the specimens shown in PL X, figs. 1 & 2, is 

 not such as to permit of a critical determination ; the leaf-cushions 

 appear to be of the type of L. aculeatum," but we do not think that 

 the Yereeniging plant is specifically identical with that species. 



Lepidodendron Pedeoanum (Carruthers). (PL IX, fig. 1.) 



The sandstone-cast of a flattened stem (21*5 centimetres by 

 10 cm.), represented three-fifths of the natural size in the figure, 

 appears to be distinct fromi. vereenigingense. The leaf-cushions are 

 shorter and relatively broader ; the breadth is from 8 to 9 milli- 

 metres, the length approximately 1 cm. : a broadly-rounded arch 

 forms the upper part of each cushion, and the sides taper rather 

 rapidly towards the lower end. In. some of the cushions it is 

 possible to detect faint indications of the parichnos and leaf-trace 

 scars, but the surface-features have been partly obliterated. A 

 Lepidoclendron of this type might be easily mistaken for Sigillaria 

 Brardi, but in the example before us the characters are clearly 

 those of a Lepidodendron. The form of the cushions agrees with 

 that of certain European species of the genus ; the agreement is, 

 however, closer with L. Pedroanum (Carr.), a South American plant 

 first described by Mr. Carruthers ^ and more recently figured by 

 Prof. Zeiller.'^ A similar type of stem is figured by Prof. Xathorst 

 from Bear Island as Lepidodendron cf. Pedroanum.^ A less distinct 

 specimen from Vereeniging, figured by one of us ^ in a former paper, 

 as probably a species of Sigillaria^ should, we think, be transferred 

 to this species. Prof. Zeiller writes that a comparison of the plant 

 represented in PL IX, fig. 1, with his Brazilian specimens leads him 

 to confirm our opinion that the South African plant is specifically 

 identical with L. Pedroanum. 



Coedaites Hislopi (Bunbury). (Texc-figs. 9 & 10, p. 121.) 



The species Nceggerathiopsis Hislopi has long been known from 

 South Africa, but the specimens recently obtained from Yereeniging 

 are less incomplete than those previously described. The examples 

 shown in text-figs. 9 & 10 demonstrate the close resemblance to 

 Gordaites more clearly than any specimens hitherto figured : that 

 represented in fig. 10 is 84 centimetres long, and appears to be
