11. ZTeber Trias und Jurapflanzen von cler Insel Kotelny ; von 

 A. G. Nathoest. Resultats Scientifique de l'expedition Polaire 

 Russe en 1900-1903, sous la direction du Baron E. Toll, section 

 C : Geologie et Paleontologie, Livr. 2, Mem. de l'Acad. Imp. des 

 Sci. de St.^Petersbourg, VIII Serie, cl. Phys.-Math., vol. xxi, No. 

 2 ; St. Petersbourg, 1907, 12 pp. and 2 pis. — The present Mesozoic 

 flora, while not extensive, is of considerable interest, since the 

 New Siberian Islands, of which Kotelny is one, have hitherto 

 yielded only Tertiary plants. G. B. w. 



12. On Triassic Species of the Genera Zamites and Pterophyl- 

 lum : Types of Fronds Belonging to the Oycadophyta ; by E. 

 A. Newell Aebee. Trans. Linn. Soc. of London, 2d ser., Bot- 

 any, Vol. VII, part 7; London, Nov., 1907, pp. 109-127, pis. 

 17-19. — In this paper it is shown that the form genus Zamites 

 includes various fronds of very large size with Monocotyledon- 

 like leaves sometimes quite 50 centimeters in length, though in 

 nearly all cases found detached. It is thus clear that various of 

 the earlier Mesozoic imprints described as Yiiccites, Cordaites, 

 Bambusium, etc., are really cycadophytes and not in themselves 

 evidence of early Monocotyls, Proangiospermeae, or persistent 

 Cordaitalean forms. G. e. w. 



13. Veg'etaux Fossiles de Normandie. IV. — Bois Divers {Ire 

 Serie) ; par Octave Lignier. Mem. Soc. Linn, de Norm. T. 

 xxii ; Caen, 1907, pp. 237-333, with pis. xvii-xxiii. — Both from 

 the extent of the subject matter and the care with which it is 

 elaborated and figured, the present memoir must rank as one of 

 the most important and satisfactory treatises which have ever 

 appeared on fossil woods. A half dozen genera of coniferous 

 and dicotyledonous woods are here studied at length. Addi- 

 tional testimonj* for the great abundance of Araucarioxylon in 

 the Jurassic and Wealden is adduced ; and the very interesting 

 determination is made that in Covmaraucarioxylon the woody 

 structure is that of the Cordaitales, thus virtually verifying the 

 view of Zeiller that such Jurassic imprints as Yuccites and Eoli- 

 rion, and even the middle Cretaceous Krannera, do include per- 

 sistent Cordaitalean forms. g. r. w.

 Afdeln 2, Band 2, Nr. 8 (Kongl. Fysioar. Sallskapets Hand. N. F., 

 Band 17, Nr. 8), 15 pp. and 2 pis. — Figures complete leaves of 

 several species of Czekanowshia and of the related ornate Gink- 

 goalean form Baiera spectabilis, showing excellent preservation 

 of epidermis, stomata, and guard cells of the Ginkgo type. We 

 note the interesting likeness between the leaves of Czekanoioskia 

 rigida and the similarly much dichotomized pinnules of the but 

 recently discovered Cycas Micholitzii Dyer of Annam.
