The horizon from which these species were obtained is proba- 
bly upper Trias. It becomes, therefore, important to re-examine 
the locality from which Professor Marsh obtained the Cælurus fra- 
gilis to determine whether its deposit is really of Jurassic age, as 
stated by Marsh. It is, however, not fixed beyond doubt that 
the New Mexican locality is Triassic. D. Co, ope. 
Geological News. GENERAL—M. Nouvy, in his “ Geolo 
of Jersey,” assumes that the island had an original granitic crust 
on which the gneisses were deposited in an intensely heated 
ocean. The sedimentary rocks are chlorite-schist, feldspathic 
schist (which is most common), metamorphic schist, and con- 
glomerate. There is much eruptive rock, varying from granitic 
to diorite. The author states that the age of the true granites 
~ now found cannot be proved, but that the other eruptive rocks 
are certainly later than the schists. No sedimentary rock exists 
between these Cambrian strata and the conglomerate, which he 
attributes to the Permian age. After a careful sifting of the evi- 
dence, he concludes that subsidence has occurred only since the 
Roman occupation, and that Jersey was probably still joined to 
Normandy in the sixth century. 
_ Devontan.—M. Ch. Deperet has studied the Devonian of the 
eastern chain of the Pyrenees. This formation forms a narrow 
band running 15° north of east, parallel to the general direction 
of the chain. The belt can be traced across the basins of the 
Aude and the Tet, from the elevated valley of the Aniége on 
the west to the plain of Reussillon on the east, and has a length 
of sixty kilometres, va a width of five kilometres at the moun- 
_tain-mass of Villefranche. The western part of this Devonian 
crest is nearly pitateaoeed. but the eastern part is cut up into 
fragments and thrown northwards by the granite-mass of Canigon. 
Mesozoic.—Dr. Carl Diener has published a monograph upon 
the Solos of the Lebanon. He has worked out the numer- 
ous lines of faulting and flexuring which have occurred, mainly 
during the Miocene, in the strata, which, both in the Leb- 
anon and Anti-Lebanon, are chiefly Cretaceous and Eocene 
Limestones. Jurassic beds occur " a narrow belt at the western 
base of Mount Hermon, which is to a great extent built upon 
the line of a great fault that Reiser with its western base. 
The limestone beds of this mountain belong to the age of the 
Lower Chalk of Europe, and are disposed in the form of a low 
arch with a north-northeast axis. There are other faults on the 
south and east flanks. Doubtless the system of disturbance here 
is identical with that which caused the Jordan-Arabah depres- 
sion; and the main line of fault of that depression enters the 
valley of the Leontes at the western base of Hermon. Here
