to a species of Bothrodcndron, but considers them specifically distinct 

 from B. kiltorkcnsc. The small forked specimen shown in fig. 4 may 

 be matched almost exactly with Nathorst's figs. 1, 2, 5, 6, 10, and 11 

 in pi. xi. of the Bear Island Memoir. The larger and more perfect 

 specimen from Yereeniging (pi. xi., fig. 1) also agrees closely with some 

 of Nathorst's examples. In spite of the close superficial agreement, I 

 believe the African plant to be a distinct species — a view which my 

 friend Mr. Kidston also unhesitatingly adopts. In the stems from 

 South x\frica I am unable to detect any trace of the two lateral scars, 

 representing the parichnos, sliown in some of Nathorst's figures of 

 the leaf-scars of Bothrodcndron kiltorkense ; the absence of the 

 parichnos scars may be due to the partial decortication of the stems. 

 Another plant which may be compared with the African species is 

 Cyclostigma australe, as figured by Feistmantel ■■'• from Devonian 

 rocks of New South Wales. This Australian type is possibly 

 identical with Haughton's species. The variation in the arrange- 

 ment of the scars is in accordance with a reference of the fossils to 

 the Lycopodiales ; striking examples of Sigillaria with leaf-scars 

 closely approximated in certain regions of the stem, and farther 

 apart in other regions, have been figured by Kidston, Zeiller, and 

 other authors. 



The Yereeniging plant appears to agree as regards the size, form and 

 arrangement of the scars with the genus Bothrodendron (including 

 under this term Cijclostujma) more closely than wdth other members 

 of the Lycopodiales. I purpose to designate the specimens Bothro- 

 dendron leslii.

A piece of a stem, 29 cm. long, and varying in breadth from 1-5 to 

 2 cm. The small piece at the upper end — as shown in the drawing 

 — is at a higher level than the rest, and shows the almost circular 

 scars as prominences with a central depression. Below this the 

 scars occur as depressions wdth a central umbo, and in some of them 

 one is able to detect a small pit in the centre of the umbo (la), the 

 pit no doubt marking the position of the vascular bundle, which 

 supplied the spirally disposed appendages. In all probability the 

 uppermost piece of the specimen is the impression of the outer, but 

 partially decorticated, surface of the organ, while the remainder of 

 the specimen represents the inner face of the compressed cortex, the 

 internal tissues — wood and pith — having been removed. At c the
