Carboniferous Si/stem in Eastern Canada. 157 



Amphibia. — Of these animals there are numerous foot- 

 prints and trails in the collections of the Geological 

 Survey or National Museum at Ottawa, belonging to 

 the genus Sauropus and of gigantic size. All other traces 

 of this genus known in America are referred to the 

 Carboniferous system. 



In his " Geology, Chemical, Physical and Strati- 

 graphical," Oxford, 1888, Prestwich gives a table " Show- 

 ing the character and distribution of the species of 

 organic remains in the several main groups of the 

 Palaeozoic series in the British Area." Under the head of 

 Amphibians (including footprints) he notes the occurrence 

 of these in the Carboniferous, but none in the Devonian. 



Miller, in his Catalogue of North American Palaeozoic 

 Fossils, does not record a single Amphibian from rocks 

 older than the Carboniferous and the genera occurring in 

 the Kiversdale formation are identical or similar to those 

 found in the Carboniferous of other regions of North 

 America. 



Dana, in his "Manual of Geology," Geikie, in his 

 " Manual " also, and all the leading writers on North 

 American Geology and Palaeontology, agree in placing the 

 genera of fossils, to which I have referred the footprints 

 from Parrsboro and Harrington Eiver, Cumberland and 

 Colchester County from the Kiversdale formation as 

 Carboniferous. Hylopus Logani and Sauropus Dawsoni, 

 N. Sp., are two of the forms discovered in these disputed 

 formations. 



Lamelli branchiata. — Of these the most conspicuous 

 are the Anthrae.omym of Salter, which Sir Wm. Dawson 

 described under the name of Naiadites. These shells are 

 abundant in the Coal Measures of the Joggins, Springhill 

 and Sydney Coal Basins of Nova Scotia, also in certain 

 portions of Virginia and other coal areas of the United 

 States, not to speak of their occurrence in the Carboni- 

 ferous of England and France and many other countries
