It would be unfair to the author if I did not make some refer- 
ence to the labours of Mr. James Hall, of the New York State 
Museum, of which he is the principal Palaeontologist, In the year 
1847 the first volume of the Palaeontology of New York w^is pub- 
lished. In it the author describes and illustrates (pi. iv.) several 
species of Polyzoa or Bryozoa from the Chasy and Trenton Lime- 
stone, which he names Betejyara, Gorgonia ? Stictopam, Escharopora 
and Intrkaria. Other volumes follow^ed in successive years, the last 
one, VL, appearing quite recently, in all of which new^ or little 
known Bryozoa, are described and figured. Since Mr. Hall began

duced into the study of the group, consequently conflicts between the 
favourers of the new or the old methods have been frequent, and at 
times, severe. It has not been my happy lot to side with either
