Sections of the carbonaceous shales placed under the 
microscope show circular or rounded objects of a peculiar 
aspect; they recall at first view sections of Radiolarians. 
Dr. Barrois submitted sections of this shale (phtanite) for 
examination by M. Cayeux, who stated that the presence 
of Radiolarians in these phtanites wus undeniable, and one 
could even refer them to Monospheride, the most primitive 
of the Radiolarians. 
“These Radiolarians are the most ancient organic re- 
mains found in France, and probably in the world; and the 
phtanites are at present classed in the Primitive Azoic 
formation about the limit of the Laurentian and pre Cam- 
brian systems.” 
By degrees cotemporaries are turning up in the Pre-Cam- 
brian rocks for the once solitary Eozoon. To Walcott’s 
minute molluscs of the Grand Cafion of the Colorado are to 
be added the Stromatapora-like fossil and the Hexactinellid 
sponge of the Pre-Cambrian rocks of St. John (Eastern 
Canada), and now the Radiolarians of Western France. 
On SomE NEw DISCOVERIES IN THE CAMBRIAN 
BEDS OF SWEDEN. 
Dr. J. C. Moberg, of Lund, has within the year that is 
past enlarged the number of species known from the Ole- 
nellus Zone of Sweden. In two pamphlets he has described 
a number of species collected by Dr. N. O. Holst and others, 
which are of peculiar interest. These are from sandstone 
boulders and beds in the south of Sweden. 
Among the fossils are two new species of Olenellus, one 
allied to O. (Holmia) Kjerulfi, but differing in the more 
strongly arched headshield, by having a much _ heavier 
cheek-spine, by.a deficient (or perhaps rudimentary) inter- 
ocular spine, by a more lengthened hypostome devoid of 
spines at the back, etc. This species he calls O. Lundgreni. 
The second species is allied to O. (Mesonacis) Michwitzi, 
from which it is distinguished by the arrangement of the 
glabellar furrows by the form of the outer part of the
