Note.—These species of gigantic extinct sloths with enor- mously powerful claws (onyx, hence the generic name) lived with gigantic Armadillos^ Mammoths^ &c., in Pennsylvania just before the Glacial and Human age set it, and some of them even later.— The large extinct fossil animal remains of the Windward islands, the Brazilian fossil tiger and armadillo lately found by Mr. Willcoxin Florida, &c., show the separation of N. and S. America as a recent event. * Megalopteris, Dawson; a genus confined to Devonian and. TLB, Suhoarhoniferous formations; related to Neuropteris on the one side, and Alethopteris on the other; having nerves like those of iV. and leaflets arranged like those of A, Its nerva- tion alone distinguishes it from Heer's genus Dan(jeopteris^ Lesquereux in Coal Flora, page 148.
