from the Lanarkshire Goal-field. 417 



plant was collected. It belongs to the group of Calamites 

 with a thick smooth bark. At the nodes the leaf-scars form 

 a chain of transversely oval contiguous scars, similar to those 

 occurring in Calamites (Calamitina) varians, var. inconstans, 

 Weiss (' Steinkohlen-Calamarien,' vol. ii. p. 69, pi. xxv.). 

 From the fragmentary nature of the specimen, however, I 

 cannot with any certainty refer it to that species. We can 

 only hope that more perfect examples will soon be found 

 which will enable us satisfactorily to determine the species.

* As the plants from this bed occur in a state of great perfection, to 

 show its exact position I append a section, which was procured for me by 

 Mr. Dunlop from Mr. Prentice, manager of the colliery.
