The generic name Lomatopteris was proposed by Schimper^ for some bipinnate fronds originally described by Kurr- from Jurassic rocks of Wtirtemberg as Odontopteris (?) jurensis (fig. 360, A). I have elsewhere expressed the opinion^ that this German species may be identical with Thinnfeldia rhom- boidalis Ett.
