The same species lias appeared in the Miocene ot northern (ireenland and Siberia, and in both ot these hitter ea'<cg lleor comments upon their very remarkable resemblance to 0 riiiali". In the 1906 collections from the Tulamcen river there was a fern which cannot well be separated from this species. It shows, however, much larger pli^iules, but this may well 1«! due to conditions of growth, since precisely parallel diticrenccH may bo found in growinj; specimens of 0. regalis. One of the characteristic features of 0. heiHi is to be found in the scrratec from the Ked Doer river, at the mouth of the Blindman. It could not be correlated with any of the previously observed Osmundas, although it may be identical with some one, pur- ticularly 0. herrii. Hut the shape of the pinnules, and especially the breadth of their bases, seems to prohibit any such association. In the circumstances it has seemed better to assign it a separate name, tho justification for wliich appears in the apparently larger size of the fronds, as hidicated by the width of the pinnules.
