of Europe. They occur in bands in the Eiversdale 

 formation at Eiversdale and in numerous outcrops along 

 the banks of the Harrington Eiver on the dividing line 

 between Colchester and Cumberland Counties, and the 

 term " Naiadites Bands " is applicable to these Eo- 

 Carboniferous bands, which are usually associated with 

 Ostracoda of the genus Carbonia and other allied genei^a 

 of Carboniferous facies, just as the term is applicable to 

 them in the Coal Measures above. All writers on 

 Geology and Palseontology concur in placing these shells 

 in the Carboniferous. All the species recorded from the 

 United States are referred to the Coal Measures, and 

 those from the Union and Eiversdale formations of 

 Colchester and Cumberland Counties of Nova Scotia are 

 Eo-Carboniferous. It will thus be seen that the palajon- 

 tological evidence adduced in the zoological collections so 

 far obtained from the Union and Eiversdale formations of 

 Nova Scotia, including Insects, Phyllopods, Crustaceans, 

 Amphibians and Lamelli branchiata, are all types which 

 are markedly akin to types well known to occur in the 

 Carboniferous of other countries and more than that even 

 in the Coal Measures of the same. 



As regards the evidence adduced from the flora col- 

 lected in the strata wlTich afforded the forms of animal 

 life just cited above, it can be truly said that it also has a 

 decided Carboniferous facies. The genera Asterophyllites, 

 Sphenopteris, Alethopteris, Cardiopteris, Stigmaria, 

 Calamites, Poacites, Cordaites are all well represented. 

 Mr. Eobert Kidston, of Stirling, Scotland, and author of 

 the British Museum Catalogue of Carboniferous Plants, 

 has examined the forms sent hini and reports that he 

 is satisfied that the flora is truly Carboniferous. 



The following are some of the species of fossil plants 

 obtained by the writer and submitted to Mr. Eobert 

 Kidston, F.E.S., F.G.S., of Stirling, Scotland, for deter-
