Clark of Berea, Ohio, whose courtesy permits me to refer to it, and it will shortly be described by Prof. Claypole. This fin seems to present the needed evidence that among the Cladosela- chids were forms which had evolved spine- shaped fins, closely suggesting the hitherto inexplicable fin struc- tures of the Acantho- dians. In the present instance the fin is nar- row, acutely pointed, its proximo-distal width nearly thrice as long as its basal length: the radials are stout, com-.
