Excerpt from Journal of the Washington Academy of Sciences, 1919, Vol. 9 The 'ensemble of the collection points to climatic conditions similar to those prevailing at present in the region, while the earliest Nome bed indicates decidedly warmer water. It is probable that this Pribilof fauna conformed to more rigorous conditions prior to the glacial epoch. The St. George collection as a whole has only seven species identical with those found at Black Bluff, St. Paul Island, which la'tter fauna is doubtless Pleistocene. With the Pliocene second elevated beach fauna at Nome one-third of the St. George collection is identical, but in this third the characteristic warmer water species are not represented. So I conclude that the material obtained by Mr. Hanna represents a period later than the Nome second beach and earlier than that of the Black Bluff fauna. A list of the species is given in table 1. The type specimens are preserved in the U. S. National Museum. Botany. - The ancestry of maize. J. H. Kempton, Bureau of Plant Industry. (communicated by William R. Maxon.)
