Remarks. This species, which was described by Goppert from the Devonian 

 Formation of Nassau, was not thought by Schimper to have much re- 

 semblance to a Conferva* The specimens from Glencartholm, which I 

 identify as Goppert's plant, are undoubtedly of organic origin, and although 

 it is impossible to affirm that they possess any relationship to the recent 

 Conferva, I believe them to be algoidal in their nature. Only two specimens 

 are in the Collection. In one, which occurs on a slab associated with Chon- 

 drites plumosa, Kidst., the filaments are bent over each other and matted 

 together, but in the other specimen the filaments are only slightly curved, 

 apparently simple and delicate, their thickness varying somewhat, but their 

 greatest width is only about 1-25 of an inch.
