occupying the highest place in the classification of the radio- 
larians. This fauna is characterized by a Complexity and a 
perfection which implies the pre-existence of several other 
radiolarian faunas of a lower type. Certain of these Pre- 
Cambrian genera persist to the present time. A more complete 
accouut of these very ancient fossils will appear in the 
"Notes et Memoires" of the Society. 
Topographical Survey of Minnesota. Under the provision 
of the state law for a Geological and Natural History Survey, 
active work has just been inaugurated for the construction of 
a finished topographical sheet of the region of the state Uni- 
versity, including St. Paul and Minneapolis. For this purpose, 
and the establishment of the necessary tertiary points for 
plane-table draughting, assistant W. C. Hodgkins, of the U. 
S. ('oast Survey, has been detailed to carry on the triangula- 
tion. Recent action of the regents in appropriating the 
necessary funds has rendered this possible. For seven years 
this connection between the State Survey and ( 'oast Survey has 
been sustained, but hitherto the expense has been incurred in 
primary and secondary triangulation. The work is in charge 
of Prof. W. R. Hoag, of the State University.
