ON THE CAMBRIAN ORGANISMS IN ACADIA. * 
By G. F. Marruew, M.A., F.R.S.C. 
[ Abstract.] 
The earlier papers describing the Cambrian animals of 
Eastern Canada, read by the writer, before this Society, have 
related to the fauna of the St. John (or Acadian) group, 
but having lately made examinations of the measures which 
underlie the Paradoxides beds, he has found evidence of a 
physical break below these beds, and that the underlying 
beds carry a different fauna, This fauna is very imperfectly 
exhibited, but is sufficiently developed to show that this 
lower, or basal series is the equivalent of the blue clay of 
Russia and the Kophyton sandstone, &c. of Sweden. 
Late developments in the palwontology of the oldest 
Cambrian beds, show that the Olenellus beds of the State of 
New York and elsewhere, are of about the same age as 
these old Acadian beds, and indications of the Olenellus 
fauna have been found by me from the middle of this basal 
series upward to the Paradoxides beds,
