fauna, or rare, selected from the thirty-five species recorded

make up the rest of the paper; which is a valuable contribution 
to that branch of Geological Science of which it treats. 
This was the last meeting of the Club for the year 1877— 
and thus terminated a season which has not been without 
pleasure or profit, nor wanting in solid contributions to the 
scientific reputation of the Cotteswold Club.
