* Although following the classification hitherto adopted in this publica- 
tion, the Recorder wishes to remark that, in his opinion, the Spongozoa should 
probably form a class by themselves. The natural classification of the lower 
animals (the Vermes of Linnaeus), however, is still an open question, and will 
change with advancing knowledge.
