This wide ranging species is abundant in both large and 

 small examples at Paracas and occurs also in the lower part 

 of the section on the Copacabanya peninsula, Bolivia. It un- 

 doubtedly represents what Steinmann called Archaeocala- 

 mites and suggests that this author's Archaeocalamites from 

 other localities in South America may represent true Cala- 

 mites. Stems of this sort have little that is truly specifically 

 characteristic, but the vascular alteration at the nodes proves 

 it to be a true Calamites and the infra nodal canals and char- 

 acter of the ribbing invite comparisons with this classic 

 species, which had a wide geological and geographical range.
