‘the foliage, and the nature of the fructification in Cycadoidea ingens 
and C. candi. The superb character of this collection, both in 
extent and perfection of preservation, as also in the very unusual 
fact that the inflorescence is preserved in great perfection of detail, 
leads us to hope for the most important results bearing upon our 
knowledge of the earlier history of these very interesting plants, and 
botanists will look forward with keen interest to the completion of 
these important studies. D. P. P.

The Yale Collection of Cycads.! — Mr. G. R. Wieland contributes 
a short account of the very remarkable collection of cycads now in 
the Yale Museum, which will prove of interest to paleobotanists as a 
concise account of the origin, number, and general character of these 
valuable specimens. In the Yale collection there are many beautiful 
cycadean fronds from the Triassic sandstones of the New Haven 
region, and more than six hundred silicified trunks chiefly from the 
Upper Jurassic of the Black Hills. In addition to these, the fact 
of three other American collections in the United States National 
Museum, the University of Wyoming at Laramie, and at the Woman’s 
College, Baltimore, is noted. Figures and general descriptions of 
thirteen species are given. prp 
Fossils of the Norwegian North Polar Expedition.’ — An inter- 
esting result of the Nansen Expedition comes to us in the form of a 
paper by A. G. Nathorst Ön the “ Fossil Plants from Franz Josef Land.” 
Twenty-nine species in all are described, and one fungus parasite on 
a coniferous leaf. The plant-bearing stratum lies between two basalt 
beds, and a comparative study shows that it is in all probability 
Jurassic, the flora corresponding most nearly with that from the 
Jurassic of Siberia and Spitzbergen. The unfortunately fragmen 
tary condition of the material leaves much in doubt as to the specific 
identity of several species, as well as of the exact horizon to which 
they belong. The following summary of species may be found of 
interest : Cladophlebis 1, Sphenopteris 4, Pterophyllum 1, Podo- 
zamites 1, Ginkgo 3, Czekanowskia 1, Phcenicopsis 1, Fieldenia 1, 
Taxites 1, Abietites 1, Pityanthus r. DIE
