(Whitby Museum; nat. size.) with N. compta is a very similar type; it was originally described by Heer as Anomozamites Schmidtii and transferred by Nathorst^ to Nilssonia: the veins are occasionally forked near the rachis and are rather farther apart (-5 mm.) than in N. compta and the segments are broader and deepei- than in the EngUsh species. Nilssonia nipponensis Yok.* a Jurassic species recorded from Japan and North America is another similar type. 1 Heer (78) ii. Pis. xxtn., xxiv.; Seward (12^) p. 27, PI. n. ' Nathorst (97) p. 13.
