Coal-measures and is subject to great variation. To many of 

 these varieties specific names have been given. 



Localities. Roof of Kiltongue Coal, Mount Vernon. Bent 

 Colliery, about lg mile E. of Both well. 



Riiacophyllum, Schimper. 



(?) Riiacophyllum Jiliforme, Gutbier, sp. 



Fucoidesjiliformis, Gutbier, Vers. d. Zwickauer Scbwarzkoblengebirges, 

 p. 12, pi. i. tig. 9. 



Remarks. Among the fossils is a small specimen of 

 Rhacophyllum with filiform segments, which, though not very 

 well preserved, is, I believe, referable to this species. 



Locality. Cutting, new Caledonian Railway, Airdrie.

 figs. 1, 2, and 4. 



Remarks. One or two very fine specimens of that form of 

 Lepidodendron Sternbergii which has been named L. lyeopo- 

 dioides by Sternberg and L. elegans by Brongniart were 

 collected from a cutting on the new Caledonian Railway, near 

 Airdrie. 



Lepidodendron elegans and L. gracile appear to be only the 

 younger and smaller branches of Lepidodendron Sternbergii 

 and not specifically distinct from that plant. 



Localities. Cutting on new Caledonian Railway, Airdrie 

 (L. elegans). Pit, Airdrie (L. Sternbergii). Bent Colliery 

 about 1^ mile E. of Bothwell (L. gracile). 



Lepidodendroid Branches. 



Under this head I include two fine slabs from Whiterigo- 

 which show on their surface a number of delicate twigs' 

 measuring in some cases 10 or 11 inches in length, and about
