* As many species of this group consist of nothing but the fibrous 

 skeleton in which the alga (Spongiophaga communis) has replaced the 

 sarcode, and many of the Hixcinida are subject to the same change, 

 it is questionable if they all belong to the group " Hirciniosa." 



t The number of references to the third part of these " Notes " for 

 illustration will show how much remains to be done in describing 

 even the different kinds of Sponges already in our Museums.
