Paleozoic Fossils. 357 



Lepidodentlron from the Bokkeveld beds of Hex River Pass, 

 Division of Worcester, as Botlwodcndron leslii, under the impres- 

 sion that it came from the Ecca beds of Yereeniging.* He also 

 points out the similaritj^ of the species with the Australian Cijclo- 

 stigma atistrale, Feistmantel, which again is almost identical with 

 the C. kiltot'kense, Haughton, from Ireland. The si/.e and spacing 

 of the vascular scars of the decorticated stem, and their relation in 

 position to the stem are the same in B. irregulare and C. australe 

 as figured by Feistmantel i, though the Witteberg stems are often 

 very much larger than the Australian ones. 



The ai-rangement of the scars is roughly spiral withoiit any 

 strong horizontal or vertical spacing. The characters of this 

 species are so close to GgcJostigiita australe that I would have 

 placed the specimens in the Albany Museum under that name had 

 not Mr. Sewai-d given a new name to the Ecca (Permian) form, 

 Bothrodendron leslii., which is also extremely close to the Austra- 

 lian lower Carboniferous species. By giving the Witteberg species 

 the name B. irregulare I wish to emphasize that our material is 

 not good enough to pronounce true identity with either G. australe 

 or B. leslii. 



Mr. Rogers^ compares the South African foi-m with the species 

 figured by Feistmantel from the Goonoo Goonoo beds of New South 

 Wales, but the wider spacing of the vascular scars in the common 

 South African Cyclustigrna refer it rather to G. australe from the 

 lower Carboniferous beds of Smith's Creek, Stroud, New South 

 Wales, and Bobuntungen beds of Queensland, associated in both 

 countries with Lepidodendron i^eltheimianum Sternb., a lower 

 Carboniferous zone fossil.
