 There are 4 hands of these rocks in this region : — that of Lustin, in 

 which the Monfort division " C " is alone present ; that of Yvoir, where 

 the Monfort and Esneux divisions " C " and " A " appear, those of Sou- 

 verain-Pre (?) " B " and Evieux " D " being absent ; that of Anseremme, 

 where A, B, C are present, but not D ; and that of Hastieres, where 

 A, B, D but not C are seen. Many sections are described. G. A. L.

In a loose brown-red sandstone, probably Triassic, lie layers and 



lenticular masses of a rose-red or light red, sometimes yellowish- white 



jasper, not exceeding five Swedish feet in length. E. E.

A collection from Tschulkowo gave 5 Ammonites identical with W. 

 European forms ; a re- examination of species described by Trautschold 

 shows that the lower beds with Ammonites alternans do not represent 

 any part of the L. Oolite as that author thought ; for the fauna is that 

 of the Kallovian and Oxfordian. The beds above these contain indi- 

 genous forms not found in W. Europe, so that the IT. Jurassic are not 

 to be paralleled with the same precision. The changes of land and sea 

 in Russian Jurassic time are enumerated thus : — 1. Crimo-Caucasian 

 phase, prior to Kallovian times a partial incursion of sea eastwards, 

 laying down marine beds with Belemnites (Lias, &c. being mostly of 

 freshwater facies in the east). 2. Sea-communication with mid-Europe 

 in Kallovian times. 3. Continued immigration of W. European forms, 

 mixed with others from India. 4. Severance from western seas and 

 indigenous fauna. 5. Extension of sea northwards. 



The new species described are : — PerispJiinctes Scopinensis from the 

 Ornatus-beds, and Waldheimia Trautscliolcli from the glauconitic lime- 

 stone. E. B. T.

The peninsula of Chalkis consists of chloritic schists, gneiss, &c., 

 with which crystalline marbles are associated, the whole bent into one 

 chief fold, with several minor ones causing repetitions ; a considerable 

 thickness of these marbles is seen in Mt. Athos. Similar limestones at 

 Hymettus, Acropolis of Athens, &c. have yielded Secondary fossils ; 

 therefore, as the metamorphic schists in N.E. Grreece are Cretaceous, 

 it is probable that the similar beds of E. Thessaiy are so also. E. B. T.
