Abstract

In this article the writers reported the occurrence of Samarae of Pteroceltis from the Tertiary rocks of Hokkaidô and Tyôsen. One (fig. 1). is derived from the Kunnui Series of Abura, Prov. Siribesi, Hokkaidô; this is unfortunately very fragmentary, but the resemblance to the samarae of modern Pteroceltis Tartarinowii MAXIM.(fig. 3) is in no small degree great, though ours is decidedly larger in size compared with the living one. Another one (fig. 2, 2a) is derived from the Engethardtia bed of Kokangen, northeastern Tyosen; this is rather perfectly preserved and is very closely allied to the samarae of the living species. The writers wish to call these fossil types from Hokkaidô and Tyôsen under the name Pteroceltis? sp. and P. sp. cfr. P. Tartarinowii MAXIM, respectively.
