Discussion. 



The Pkesident remarked that while there was little in such a 

 paper as that before the Meeting which could have interested the 

 Fellows had it been read in full, the paper was nevertheless of 

 great value as containing many most useful observations upon a 

 very important group of Pala?ozoic fossils. 



Mr. Goodchild stated that Miss Donald had not only studied most 

 carefully the fossils of the northern district in which she resides, but 

 she had also pursued her researches during visits to many museums 

 in this country aud also on the continent of Europe.
