bent, especially in the neiglibourliood of the leaf-scars round 

 which they curve, and immediately below and above the 

 leaf-scars tliey are absent, having the appearance as if they 

 had separated to make room for the scars. There is, how- 

 ever, no " field," as in Lepidodendron. 



I have named this species " Wiildamtm" as there seems 

 to be a great probability that this plant is similar to Heer's 

 Lepidodendron Wiikiamcm, from Bear Island.^ Tlie British 

 specimens are not, however, referable to the genus Zej^i- 

 dodcndron, and, judging from Heer's figures and description, 

 I do not think that his plant should be placed in that 

 genus. As, however, I have not seen any of Heer's speci- 

 mens, I cannot be certain that his species is identical 

 with my Botlirodendron Wiikianum, though I am strongly 

 inclined to believe it is. I therefore, while adopting his 

 specific name, place the British specimens in their proper 

 genus; and should it eventually be proved that these 

 two species are identical, it will be an easy transition to 

 substitute B. Wiikiamcm, Heer, sp., for B. Wiikianum, 

 Kidston.

In my " Catalogue of Palaeozoic Plants in the Collection of 

 the British Museum," ^ I stated the belief that the leaf-scar 

 of Cyclostigma, Haughton,^ did not differ in any character 

 from those of Rliytidodendron, which is now known to be 

 synonymous with Botlirodendron. Last year I had the 

 opportunity of examining the fine collection of Kiltorkan 

 fossils in the Science and Art Museum, Dublin, and in the 

 collection of the Geological Survey of Ireland, Dublin, and
