sharp plane of demarcation between the Silurian and Old Red Sand- 
stone. It is now known that the Tilestones (passage-beds) and 
underlying minor Silurian divisions, met with 40 miles further west, 
are not present in the Usk district, unless represented by strata of 
wholly different characters. The list of Silurian fossils has been 
revised, and the nomenclature in the earlier edition modified in a way 
that may be said to render comparisons odious. 
The Old Red Sandstone is now separated into Upper and Lower 
divisions, with the Brownstones in the upper part; but no evidence 
of unconformity in the formation has been detected. 
Some observations have been made by Mr. E. E. L. Dixon on the 
zonal divisions in the Carboniferous Limestone of the Newport area, 
and the absence of the higher portions of the Limestone Series is 
attributed to the unconformable overstep of the Millstone Grit.

\ROM a series of papers extracted from osmos (Lemberg), 1909, 
vol. xxxiv, we gather that Jan Nowak describes the Cephalopod 
fauna of the uppermost Senonian (Campanian) of the Carpathians. 
The fauna was collected by Professor R. Zuber in Galicia and includes 
such well-known forms as Baculites anceps, Lam., Scaphites constrictus, 
Sow., S. tenuistriatus, Kner, and Belemnites bipartitus, Bl. With 
these occurs a form called ‘‘ Znoceramus Cripsi, Mant.” This unfor- 
tunate species seems to give endless trouble to Continental authors, 
and it may as well again be stated that the type in the British Museum 
is an internal cast, without any shell whatever, and came from the 
Chalk Marl of Offham. In England it is certainly a Cenomanian 
fossil, and there is nothing like it in the higher beds. Dr. Zuber 
describes the stratigraphy and tectonics of the Galician Carpathians in 
the same volume, and after an appropriate summary of previous 
authors, gives a lucid sketch of the geology, illustrated with many 
sections. But here also Znoceramus Crips? is associated with Belemni- 
tella mucronata, which seems an impossible thing to those who know 
the fauna of the Chalk of England. Dr. W. Rogala, who discusses 
this very point in a communication to the same volume, says on 
p-. 742 of his paper: ‘‘ Wszystkie formy z Lopuszki W. dadza sie 
pomiesoic w obrebie gatunku Jnoceramus Cripsi, Mant., jaki temu 
gatunkowi nadal Zittel. Nowsze jednak badania Petraschecka 
wykazuja, ze formy gosawskie sa weale rozne od oryginalu Mantell a, 
a badania J. Bohma wykazuja rowniez, ze i formy Goldfussa sa od 
niego rozne; wobec tego obydwaj ci autorowie nazwe J. Cripsi, 
Mantell zaciesniaja, a liozne formy dotychezas nia obejmowane 
oddzielaja jako osobne gatunki,” and omits Z. Crips’, Mant., from his 
list on p. 745, using the name J. (cf.) regularis, d’ Orb., instead. 
Other interesting papers in this volume are on the fish fauna of the 
menilit-beds (Lower Oligocene) of the Carpathians, by Jan Rychlioki, 
and one on the Titonian Klippen at, Kruhel Wielki, near Przemysl, by 
Dr. Zuber. These seem to be composed of foundered Inoceramus-bed, 
with exotic blocks of Stramberger Titonian.
