REPORT OH THE POLYZOA. 
15 
The separation of this peculiar form from Catenicella is entirely artificial, and it has 
been placed under Catenaria simply for its mode of branching, and the absence of any 
lateral appendages.

what I had originally named “operculum,” now generally employed for the oral valve, I have adopted his name.
