Desmazieres on Cryptogamia new to France. — M. Tulasne on French Ly coper dacece. July. — Zoology. — M. Serres on the human allantoic!. — M. d'Or-bigny on the Gasteropoda of the Cretaceous system. Of 325 spe-cies found in the cretaceous strata of France, 250 are new. Out of the total, 81 species belong to the Neocomian (the lowest portion of the Lower Greensand) and 9 to the " Aptien," which two divi-sions form together the " Etage Neocomien" of D'Orbigny, a name equivalent to the Lower Greensand of Dr. Fitton. To the "Albien," i. e. the Gault, belong 77 species; to the " Turonien," i. e. Upper Greensand, 134; and to the " Senonien," i. e. white chalk, 24. Each geological group is marked by an assemblage of peculiar species. The new names given by M. d'Orbigny to the groups will appear to most geologists useless and inconvenient : it is a relic of an old, but very bad habit of French naturalists. — Experimental researches on Inanition, by Dr. Chossat.
