pean forms, so conspicuous in the lower horizons, gradually di- 

 minishes upwards. The " autochthonic " forms of the Moscow 

 Jurassic fauna, that is, those originated within the Centro-Kussian 

 Basin by transformation (?) of immigrated Western-European forms, 

 are associated with the transformed (?) offspring of Indian immi- 

 grants (as some PerispMnctes, standing next to P. frequens, Oppel, a 

 Tibetan form); and, in division c, with those from a third (northern) 

 origin, such as Amaltlieus catenuJatus. 



From all these facts, Dr. Neuraayr endeavours to trace five distiiict 

 phases in the formation of the Eussian Jurassics : — 



1. Crimeo-Caucasian phase. Previously to the deposit of the 

 " Kelloway " beds the Russian Basin is invaded by the sea, and 

 Belemnitic shales, analogous to those of the Crimea and the Cau- 

 casus, are deposited. 



2. Free communication with the Centro-European sea existing 

 during the " Middle Callovian" Period, immigration and exclusive 

 prevalence of a Fauna of unmixed Centro-European type obtain. 



3. Continued immigration of Western forms ; and immigration of 

 others from the newly opened Indian Sea, in the beginning of the 

 " Oxfordian " Period ; with transformation (?) of the immigrants 

 into autochthonic forms. 



4. Connexion with the Western Sea closed ; development of a 

 special Russian Fauna in the PerispMnctes virgatns beds; Centro- 

 European forms only represented by analogous species. 



5. Great Northern transgression, coeval with the deposition of the 

 Ancella beds ; communication with the Northern Sea (probably 

 already existing) notably enlarged ; immigration of Aucella, Amal- 

 theus catenulatiis, and other extraneous types. 



Dr. Neumayr described two new species : PerispMnctes scopinensis 

 from the Ornatus-clays, and Waldheimia Traiitscholdi from the 

 glauconitic limestones of Tchoulkowo. 



IV. — Remains of Man and Pleistocene Animals in the Loess of 

 THE Danube. (From the Vienna Imperial Acad. Sciences, 

 Meeting February 1, 1877.) 



THE Danube, during the Diluvial (Pleistocene) Period, covered 

 all the northern portion of the Vienna Basin ; and left, on its 

 retreat to its present channel, a thick deposit of laminated loam 

 (Loess), overlying the Tertiaries. Near Zeiselberg, at the mouth of 

 the Kamp Valley, Count Wurmbrand discovered in 1876, beneath 

 unmoved layers of Loess, a rich deposit of bones, and under that 

 a blackish stratum abounding with fragments of charcoal and 

 with flints bearing traces of human workmanship. Other deposits 

 also with bones and worked flints exist in the neighbourhood. 

 The bones in the Loess here are those of Diluvial (Pleistocene) 

 animals, namely. Mammoth, Rhinoceros, Reindeer, Horse, Ox, 

 Wolf, and Bear. The local conditions contradict the supposition that 

 these remains were carried to their present position from a distance 

 by currents of water or other agency. The excavations are still going 

 on, partly at the expense of the Vienna Academy. Count M.
