S. Stefanescu at Seciiirile, etc. At Cucesti and Slatiora I collected a 

 fauna which was investigated by Professor N. Andrussow, who was 

 good enough to communicate his results to me. He found: 



Dreisscnsia tenuissima Sinz Neritinae sp. 



Dreissensia Berbestiensis Font. Prosodacua Munieri Sabba. 



Prosodacra litloralis Eichw. Didacua placida Sabba. 



Vivipara bifarcinata Biettz. Limnocardhtm aff. ochelophorum. 



Vivipara Woodwardi Brus. Pyrgula aff. Siuzowi Andr. 



Vivipara Sadleri Partz Hydrobiae sp. 



Cardidae sp. Pisidium sp. 



According to the determination by Professor Andrussow, as he 

 himself expresses it, this horizon contains a fauna with species char- 

 acteristic of the blue clay facies from Odessa, and also species 

 belonging to the upper layers between the Pontic and Psilodon assise. 

 This horizon corresponds to the 77 horizon of the Pontic stage, accord- 

 ing to the classification of Professor Andrussow. 1 Fontannes 2 and 

 Sabba Stefanescu 3 classify the zone Cucesti-Berbesti among the 

 highest layers of the Pontic (s. s.) stage, which is in accordance with 

 my observations. Professor Andrussow adds, however: 



I have noted in several places (see in particular the synoptic tables in the 

 Monograph of Dreissensidae) that the Roumanian Pontic stage does not quite 

 correspond to the layers which are understood under this name in southern 

 Russia, Austria, Austria-Hungary, and even in Italy. The lowest limit of the 

 Roumanian Pontic — the Congeria layers — does, indeed, coincide with that of the 

 south Russian Pontic, but the upper limit in Roumania is much higher than 

 that between the Pontic and Levantine stages in Hungary and the southern 

 Slavonic countries. Accordingly, the upper part of the Roumanian Congeria, or 

 better Cardium layers, which are called Pontic by many authors, correspond to 

 the deposits which in other districts are classified as Levantine. 



Southwest from Slatioara, on the highroad near Cerna, and at 

 Cristanesti (north of Cucesti), I found in the marls an intercalation 

 of sandstone and sand which, like the horizon from Bengesti, contains 

 many fossils: Cardidae, Prosodacnae, Dreissensidae, Hydrobiae, etc.
