(1) Tarraskis problematicus Traquair is shown to be a Palæoniscid having the bones of the head, axial skeleton, median fin supports, and “palæniscoid” scales characteristic of the group.
(2) Tarrasius is specialized in that it has become an eel-like swimmer, and on account of this has continuous dorsal and ventral fins, a diphycercal tail, lobed vertically held pectoral fins, and no pelvic fins.
(3) Tarrasius shows how a somewhat eel-like Palæoniscid may exist, and in consequence supports the view of Goodrich that Polypterus is a Palæoniscid.
