The above list of species is interesting in that it shows the diversity of structure 

 among the Coal Measures Amphibia. There are at present 88 species known, many 

 of them incompletely, divided among 17 families and 5 orders. The majority of the 

 species are from the Linton Coal Measures, there being 50 species described or indi- 

 cated from these beds. The Mazon Creek shales have furnished 10 species; Nova 

 Scotia 1 8 species; the remainder of the species are from various localities.
