Besides the above-listed species there are others indicated by fragments too 

 poorly preserved to be worthy of specific designation. The Linton Amphibia are all 

 apparently confined exclusively to that locality. Species from the Cannelton slates 

 have been assigned, however, to genera which occtir at Linton, i.e., Erpctosaurus and 

 Tuditanus. This reference may be due to lack of knowledge, as the forms are insuf- 

 ficiently known. A single Linton species has been assigned to Ichthyerpeton, a genus
