CoNTiNTTiNG to adopt the practice whicb I have hitherto regarded 

 as ^;he most useful — that of making the Addresses delivered at 

 the; Anniversary Meetings of the Society reports of tbe progress 

 of discovery in certain departments of zoological research — I 

 have this year chosen for my subject the structure and develop-

 tend over a period wMch dates from tbe publication of my own 

 early researches on this group *. 



Unless we include among them the genus 'Bhdbdo'gleura\ , all 

 the Phylactolsemata are inhabitants of fresh water. One of their

 into the group of the Phylactolsemata. The characters which at first sight
