Abstract
LENINGRAD. Academy of Sciences (Comptes rendus, No. 2, 1928). —B. A. Fedorovič: Multi-coloured sandstones of the Crimea. Pliocene deposits in Crimea are partly continental, partly marine in origin, and their fossil fauna presents evidence of considerable fluctuations in the climate of the Pliocene period.—A. Frank-Kamenetzky and N. Waksberg: Hydrochemical investigations of hot springs at Lake Baikal. Three hot springs studied belong to the category of thermal springs. In two of them the temperature of the water is 43-44° C., while in the third it is above 70°. The water is not strongly mineralised, but contains 15-30 per cent of silicic acid.—N. Olenev: Classification and geographical distribution of Ixodoidea. Notes on synonymy, morphology, and distribution of nine species of the genus Hœmaphysalis, including two new species. The distribution of Hyalomma syriacum is the same as that of its hosts, terrestrial tortoises of the genus Testudo. A doubtful species, Ixodes arenicola Eichwald 1830, is probably a synonym of Hyalomma œgyptium L.—N. M. Kulagin: A contribution to the biology of Tylenchus scandens Schn. The wheat nematodes have been found recently in many localities of Russia, always in galls, and never in grain, as recorded by other authors. More than five thousand young nematodes were reared from one gall. Dried nematodes survived at temperatures up to 88° C., but nematodes in water died at 50°.
