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

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

 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
