In. the following papers by Professor Nicholson the author treats of 
American Palzozoic Polyzoa chiefly ; but as the papers have been pub- 
lished in this country as well as in America, their study should not be 
neglected. Those on the Devonians of America are especially valuable 
to the palzontologist.
